+_title: Ethers ASM Dialect
+
+_section: Ethers ASM Dialect @<asm-dialect>
+
+This provides a quick, high-level overcview of the **Ethers ASM Dialect**
+for EVM, which is defined by the [Ethers ASM Dialect Grammar](link-ethers-asm-grammar)
+
+Once a program is compiled by a higher level langauge into ASM (assembly),
+or hand-coded directly in ASM, it needs to be assembled into bytecode.
+
+The assembly process performs a very small set of operations and is
+intentionally simple and closely related to the underlying EVM bytecode.
+
+Operations include embedding programs within programs (for example the
+deployment bootstrap has the runtime embedded in it) and computing the
+necessary offsets for jump operations.
+
+The [Command-Line Assembler](cli-asm) can be used to assemble an
+//Ethers ASM Dialect// file or to disassemble bytecode into its
+human-readable (ish) opcodes and literals.
+
+
+_subsection: Opcodes @<asm-dialect-opcode>
+
+An **Opcode** may be provided in either a //functional// or
+//instructional// syntax. For Opcodes that require parameters,
+the //functional// syntax is recommended and the //instructional//
+syntax will raise a warning.
+
+@TODO: Examples
+
+
+_subsection: Labels @<asm-dialect-label>
+
+A **Label** is a position in the program which can be jumped to. A
+``JUMPDEST`` is automatically added to this point in the assembled
+output.
+
+@TODO: Exmaples
+
+
+_subsection: Literals @<asm-dialect-literal>
+
+A **Literal** puts data on the stack when executed using a ``PUSH``
+operation.
+
+A **Literal** can be provided using a [[datahexstring]] or a decimal
+byte value.
+
+@TODO: exmples
+
+
+_subsection: Comments @<asm-dialect-comment>
+
+To enter a comment in the **Ethers ASM Dialect**, any text following
+a semi-colon (i.e. ``;``) is ignored by the assembler.
+
+
+_subsection: Scopes @<asm-dialect-scope>
+
+A common case in Ethereum is to have one program embedded in another.
+
+The most common use of this is embedding a Contract **runtime bytecode**
+within a **deployment bytecode**, which can be used as **init code**.
+
+When deploying a program to Ethereum, an **init transaction** is used. An
+//init transaction// has a null ``to`` address and contains bytecode in
+the ``data``. This ``data`` bytecode is a program, that when executed
+returns some other bytecode as a result, this restul is the bytecode
+to be installed.
+
+Therefore it is important that embedded code uses jumps relative to itself,
+not the entire program it is embedded in, which also means that a jump
+can **only** target its own scope, no parent or child scopes. This is
+enforced by the assembler.
+
+A scope may access the offset of any child [[asm-dialect-datasegment]] or
+child [[asm-dialect-scope]] (with respect to itself) and may access the length
+of any [[asm-dialect-datasegment]] or [[asm-dialect-scope]] anywhere in the program.
+
+Every program in the **Ethers ASM Dialect** has a top-leve scope named ``_``.
+
+
+_subsection: Data Segment @<asm-dialect-datasegment>
+
+A **Data Segment** allows arbitrary data to be embedded into a program,
+which can be useful for lookup tables or deploy-time constants.
+
+An emtpty **Data Segment** can also be used when a labelled location is
+required, but without the ``JUMPDEST`` which a [[asm-dialect-label]] adds.
+
+@TODO: Example
+
+
+_subsection: Links @<asm-dialect-links>
+
+A **Link** allows access to a [[asm-dialect-scope]], [[asm-dialect-datasegment]] or [[asm-dialect-label]].
+
+To access the byte offset of a labelled item, use ``$foobar``.
+
+For a [[asm-dialect-label]], the target must be directly reachable within this scope. For
+a [[asm-dialect-datasegment]] or a [[asm-dialect-scope]], it can be inside the same scope or any
+child scope.
+
+For a [[asm-dialect-datasegment]] or a [[asm-dialect-label]], there is an additional type of
+**Link**, which provides the length of the data or bytecode respectively. A
+**Length Link** is accessed by ``#foobar`` and is pushed on the stack as a
+literal.
+
+
+_subsection: Stack Placeholders @<asm-dialect-placeholder>

+The provider this signer was established from.
+

+
+
+_subsection: JsonRpcUncheckedSigner @<provider-jsonrpc-uncheckedsigner> @INHERIT<[[signer]]>
+The JSON-RPC API only provides a transaction hash as the response when a
+transaction is sent, but the ethers Provider requires populating all details
+of a transaction before returning it. For example, the gas price and gas limit
+may be adjusted by the node or the nonce automatically included, in which case
+the opaque transaction hash has discarded this.
+
+To remedy this, the [[signer-jsonrpc]] immeidately queries the provider for
+the details using the returned transaction hash to populate the [[provider-transactionresponse]]
+object.
+
+Some backends do not respond immediately and instead defer releasing the
+details of a transaction it was responsible for signing until it is mined.
+
+The **UncheckedSigner** does not populate any additional information and will
+immediately return the result as a mock [[provider-transactionresponse]]-like
+object, with most of the properties set to null, but allows access to the
+transaction hash quickly, if that is all that is required.

+
+An **Address** is a [[datahexstring]] of 20 bytes (40 nibbles), with optional
+mixed case.
+
+If the case is mixed, it is a **Checksum Address**, which uses a specific pattern

+
+The **ICAP Address Format** was an early attempt to introduce a checksum
+into Ethereum addresses using the popular banking industry's
+[IBAN](link-wiki-iban)
+format with the country code specified as **XE**.
+
+Due to the way IBAN encodes address, only addresses that fit into 30 base-36
+characters are actually compatible, so the format was adapted to support 31
+base-36 characters which is large enough for a full Ethereum address, however
+the preferred method was to select a private key whose address has a ``0`` as
+the first byte, which allows the address to be formatted as a fully compatibly
+standard IBAN address with 30 base-36 characters.
+
+In general this format is no longer widely supported anymore, however any function that
+accepts an address can receive an ICAP address, and it will be converted internally.

+To convert an address into the ICAP format, see [getIcapAddress](utils-getIcapAddress).

+
+_heading: Why not BigNumber.js, BN.js, BigDecimal, etc?
+
+Everyone has their own favourite Big Number library, and once someone
+has choosen one, it becomes part of their identity, like their editor,
+vi vs emacs. There are over 100 Big Number libraries on [npm](link-npm-query-bignumber).
+
+One of the biggest differences between the Ethers [[bignumber]] object and
+other libraries is that it is immutable, which is very important when
+dealing with the asynchronous nature of the blockchain.
+
+Capturing the value is not safe in async functions, so immutability
+protects us from easy to make mistakes, which is not possible on the
+low-level library's objects which supports myriad in-place operations.
+
+Second, the Ethers [[bignumber]] provides all the functionality required
+internally and should generally be sufficient for most developers while
+not exposing some of the more advanced and rare functionality. So it will
+be eaiser to swap out the underlying library without impacting consumers.
+
+For example, if [[link-npm-bnjs]] was exposed, someone may use the
+greatest-common-denominator functions, which would then be functionality
+the replacing library should also provide to ensure anyone depending on
+that functionality is not broken.
+
+
+_heading: Why BN.js??
+
+The reason why [[link-npm-bnjs]] is used internally as the big
+number is because that is the library used by [[link-npm-elliptic]].
+
+Therefore it **must** be included regardless, so we leverage that
+library rather than adding another Big Number library, which would
+mean two different libraries offering the same functionality.
+
+This has saved about 85kb (80% of this library size) of library size
+over other libraries which include separate Big Number libraries for
+various purposes.
+
+
+_heading: Why not allow us to set a global Big Number library?
+
+Another comment that comes up frequently is tha desire to specify a
+global user-defined Big Number library, which all functions would
+return.
+
+This becomes problematic since your code may live along side other
+libraries or code that use Ethers. In fact, even Ethers uses a lot
+of the public functions internally.
+
+If you, for example, used a library that used ``a.plus(b)`` instead
+of ``a.add(b)``, this would break Ethers when it tries to compute
+fees internally, and other libraries likely have similar logic.
+
+But, the [[bignumber]] prototype is exposed, so you can always add a
+``toMyCustomBigNumber()`` method to all [[bignumber]]'s globally
+which is safe.

+private keys.
+
+
+_heading: Properties
+
+_property: hdNode.privateKey => string<[[datahexstring]]<32>>

+
+_property: hdNode.publicKey => string<[[datahexstring]]<33>>
+The (compresses) public key for this HDNode.
+
+_property: hdNode.fingerprint => string<[[datahexstring]]<4>>
+The fingerprint is meant as an index to quickly match parent and
+children nodes together, however collisions may occur and software
+should verify matching nodes.
+
+Most developers will not need to use this.
+
+_property: hdNode.parentFingerprint => string<[[datahexstring]]<4>>
+The fingerprint of the parent node. See //fingerprint// for more
+details.
+
+Most developers will not need to use this.
+
+_property: hdNode.address => string<[[address]]>
+The address of this HDNode.
+
+_property: hdNode.mnemonic => [[hdnode-mnemonic]]
+The mnemonic of this HDNode, if known.
+
+_property: hdNode.path => string
+The path of this HDNode, if known. If the //mnemonic// is also known,
+this will match ``mnemonic.path``.
+
+_property: hdNode.chainCode => string<[[datahexstring]]<32>>
+The chain code is used as a non-secret private key which is then used
+with EC-multiply to provide the ability to derive addresses without
+the private key of child non-hardened nodes.
+
+Most developers will not need to use this.
+
+_property: hdNode.index => number
+The index of this HDNode. This will match the last component of

+
+Most developers will not need to use this.
+
+_property: hdNode.depth => number
+The depth of this HDNode. This will match the number of components
+(less one, the ``m/``) of the //path//.
+
+Most developers will not need to use this.
+
+_property: hdNode.extendedKey => string
+A serialized string representation of this HDNode. Not all properties
+are included in the serialization, such as the mnemonic and path, so
+serializing and deserializing (using the ``fromExtendedKey`` class
+method) will result in reduced information.
+
+
+_heading: Methods
+
+_property: hdNode.neuter() => [[hdnode]] @SRC<hdnode>
+Return a new instance of //hdNode// with its private key removed
+but all otehr properties preserved. This ensures that the key
+can not leak the private key of itself or any derived children,
+but may still be used to compute the addresses of itself and
+any non-hardened children.
+
+_property: hdNode.derivePath(path) => [[hdnode]]  @SRC<hdnode>
+Return a new [[hdnode]] which is the child of //hdNode// found
+by deriving //path//.

+There was an error communicating with a server.
+
+_property: Logger.errors.TIMEOUT
+A timeout occurred.
+
+_property: Logger.errors.BUFFER_OVERRUN
+The amount of data needed is more than the amount of data required,
+which would cause the data buffer to read past its end.
+
+_property: Logger.errors.NUMERIC_FAULT
+There was an invalid operation done on numeric values.
+
+Common cases of this occur when there is [[link-wiki-overflow]],

+
+_property: Logger.errors.MISSING_NEW
+An object is a Class, but is now being called with ``new``.
+
+_property: Logger.errors.INVALID_ARGUMENT
+The type or value of an argument is invalid. This will generally also
+include the ``name`` and ``value`` of the argument. Any function which
+accepts sensitive data (such as a private key) will include the string
+``[REDACTED]]`` instead of the value passed in.

+Too many parameters we passed into a function.
+

+An attempt to call a blockchain contract (getter) resulted in a
+revert or other error.
+
+_property: Logger.errors.INSUFFICIENT_FUNDS
+The account is attempting to make a transaction which costs more than is
+available.
+
+A sending account must have enough ether to pay for the value, the gas limit
+(at the gas price) as well as the intrinsic cost of data. The intrinsic cost
+of data is 4 gas for each zero byte and 68 gas for each non-zero byte.

+The nonce being specified has already been used in a mined transaction.
+
+_property: Logger.errors.REPLACEMENT_UNDERPRICED
+When replacing a transaction, by using a nonce which has already been sent to
+the network, but which has not been mined yet the new transaction must specify
+a higher gas price.
+
+This error occurs when the gas price is insufficient to //bribe// the transaction
+pool to prefer the new transaction over the old one. Generally, the new gas price
+should be about 50% + 1 wei more, so if a gas price of 10 gwei was used, the
+replacement should be 15.000000001 gwei.

+When estimating the required amount of gas for a transaction, a node is queried for
+its best guess.
+
+If a node is unable (or unwilling) to predict the cost, this error occurs.
+
+The best remedy for this situation is to specify a gas limit in the transaction

+_subsection: Custom UTF-8 Error Handling @<utf8error>
+
+When converting a string to its codepoints, there is the possibility
+of invalid byte sequences. Since certain situations may need specific
+ways to handle UTF-8 errors, a custom error handling function can be used,
+which has the signature:
+
+_property: errorFunction(reason, offset, bytes, output [ , badCodepoint ]) => number
+The //reason// is one of the [UTF-8 Error Reasons](utf8error-reasons), //offset// is the index
+into //bytes// where the error was first encountered, output is the list
+of codepoints already processed (and may be modified) and in certain Error
+Reasons, the //badCodepoint// indicates the currently computed codepoint,
+but which would be rejected because its value is invalid.
+
+This function should return the number of bytes to skip past keeping in
+mind the value at //offset// will already be consumed.
+
+_heading: UTF-8 Error Reasons @<utf8error-reasons> @SRC<strings/utf8:Utf8ErrorReason>
+
+_property: ethers.utils.Utf8ErrorReason.BAD_PREFIX
+A byte was encountered which is invalid to begin a UTF-8 byte
+sequence with.
+
+_property: ethers.utils.Utf8ErrorReason.MISSING_CONTINUE
+A UTF-8 sequence was begun, but did not have enough continuation
+bytes for the sequence. For this error the //ofset// is the index
+at which a continuation byte was expected.
+
+_property: ethers.utils.Utf8ErrorReason.OUT_OF_RANGE
+The computed codepoint is outside the range for valid UTF-8
+codepoints (i.e. the codepoint is greater than 0x10ffff).
+This reason will pass the computed //badCountpoint// into
+the custom error function.
+
+_property: ethers.utils.Utf8ErrorReason.OVERLONG
+Due to the way UTF-8 allows variable length byte sequences
+to be used, it is possible to have multiple representations
+of the same character, which means
+[overlong sequences](link-wiki-utf8-overlong)
+allow for a non-distinguished string to be formed, which can
+impact security as multiple strings that are otherwise
+equal can have different hashes.
+
+Generally, overlong sequences are an attempt to circumvent
+some part of security, but in rare cases may be produced by
+lazy libraries or used to encode the null terminating
+character in a way that is safe to include in a ``char*``.
+
+This reason will pass the computed //badCountpoint// into the
+custom error function, which is actually a valid codepoint, just
+one that was arrived at through unsafe methods.
+
+_property: ethers.utils.Utf8ErrorReason.OVERRUN
+The string does not have enough characters remaining for the
+length of this sequence.
+
+_property: ethers.utils.Utf8ErrorReason.UNEXPECTED_CONTINUE
+This error is similar to BAD_PREFIX, since a continuation byte
+cannot begin a valid sequence, but many may wish to process this
+differently. However, most developers would want to trap this
+and perform the same operation as a BAD_PREFIX.
+
+_property: ethers.utils.Utf8ErrorReason.UTF16_SURROGATE
+The computed codepoint represents a value reserved for
+UTF-16 surrogate pairs.
+This reason will pass the computed surrogate half
+//badCountpoint// into the custom error function.
+
+
+
+_heading: Provided UTF-8 Error Handling Functions
+
+There are already several functions available for the  most common
+situations.

+_property: ethers.utils.Utf8ErrorFuncs.ignore @<utf8error-ignore> @SRC<strings/utf8:ignoreFunc>

+any following continuation bytes) from the final string as well as permit
+overlong sequences to be converted to their equivalent string.
+
+_property: ethers.utils.Utf8ErrorFuncs.replace @<utf8error-replace> @SRC<strings/utf8:replaceFunc>
+This will replace all invalid sequences (by consuming invalid prefix bytes and
+any following continuation bytes) with the

+The value (in wei) for this transaction.
+
+_property: unsignedTransaction.chainId => number
+The chain ID for this transaction. If the chain ID is 0 or null,

+used, unless overridden in a signature.
+
+
+_heading: Transaction @<types-transaction>
+A generic object to represent a transaction.
+
+_property: transaction.hash => string<[[datahexstring]]<32>>
+The transaction hash, which can be used as an identifier for
+//transaction//. This is the keccak256 of the serialized RLP encoded
+representation of //transaction//.
+
+_property: unsignedTransaction.to => string<[Address](address)>
+The address //transaction// is to.
+
+_property: transaction.from => string<[Address](address)>
+The address //transaction// is from.
+
+_property: transaction.nonce => number
+The nonce for //transaction//. Each transaction sent to the network
+from an account includes this, which ensures the order and
+non-replayability of a transaction. This must be equal to the current
+number of transactions ever sent to the network by the **from** address.
+
+_property: transaction.gasLimit => [[bignumber]]
+The gas limit for //transaction//. An account must have enough ether to
+cover the gas (at the specified **gasPrice**). Any unused gas is
+refunded at the end of the transaction, and if there is insufficient gas
+to complete execution, the effects of the trasaction are reverted, but
+the gas is **fully consumed** and an out-of-gas error occurs.
+
+_property: transaction.gasPrice => [[bignumber]]

+The data for //transaction//. In a contract this is the call data.
+
+_property: transaction.value => [[bignumber]]
+The value (in wei) for //transaction//.
+
+_property: transaction.chainId => number
+The chain ID for //transaction//. This is used as part of

+networks.
+
+For example, if a transaction was made on ropsten with an account
+also used on homestead, it would be possible for a transaction
+signed on ropsten to be executed on homestead, which is likely

+The s portion of the elliptic curve signatures for //transaction//.
+
+_property: transaction.v => number
+The v portion of the elliptic curve signatures for //transaction//.
+This is used to refine which of the two possible points a given

+serialized transaction is returned, which can be used to compute the
+hash necessary to sign.
+
+This function uses [[link-eip-155]] if a chainId is provided,
+otherwise legacy serialization is used. It is **highly** recommended
+to always specify a //chainId//.
+
+If //signature// includes a chain ID (explicitly or implicitly by using an
+[[link-eip-155]] ``v`` or ``_vs``) it will be used to compute the
+chain ID.
+
+If there is a mismatch between the chain ID of //transaction// and //signature//

+_title: Assembler
+
+_section: Assembler @<cli-asm>
+
+The assembler Command-Line utility allows you to assemble the
+[Ethers ASM Dialect](asm-dialect) into deployable EVM bytecode
+and disassemle EVM bytecode into human-readable mnemonics.
+
+
+_subsection: Help
+
+_code: asm-help.txt
+
+
+_subsection: Example Input Files
+
+_definition: **SimpleStore.asm**
+
+_code: asm-simplestore-asm.txt
+
+_definition: **SimpleStore.bin**
+
+_code: asm-simplestore-bin.txt
+
+_note: Note: Bytecode File Syntax
+A bin file may be made up of multiple blocks of bytecode, each may
+optionally begin with a ``0x`` prefix, all of which **must** be of
+even length (since bytes are required, with 2 nibbles per byte)
+
+All whitespace is ignored.
+
+_subsection: Assembler Examples
+
+The assembler converts an [Ethers ASM Dialect](asm-dialect) into
+bytecode by running multiple passes of an assemble stage, each pass
+more closely approximating the final result.
+
+This allows small portions of the bytecode to be massaged and tweaked
+until the bytecode stablizes. This allows for more compact jump
+destinations and for code to be include more advanced meta-programming
+techniques.
+
+_code: asm-examples-assemble.txt
+
+_heading: Options
+
+_definition: **-\-define KEY=VALUE** //or// **-\-define FLAG**
+This allows key/value pairs (where the value is a string) and
+flags (which the value is ``true``) to be passed along to the
+assembler, which can be accessed in
+[Scripting Blocks](asm-dialect-scripting), such as ``{{= defined.someKey }}``.
+
+_definition: **-\-ignore-warnings**
+By default any warning will be treated like an error. This enabled
+by-passing warnings.
+
+_definition: **-\-pic**
+When a program is assembled, the labels are usually given as an
+absolute byte position, which can be jumped to for loops and
+control flow. This means that a program must be installed at a specific
+location.
+
+Byt specifying the **Position Independent Code** flag, code
+will be generated in a way such that all offsets are relative, allowing
+the program to be moved without any impact to its logic.
+
+This does incur an additional gsas cost of 8 gas per offset access though.
+
+_definition: **-\-target LABEL**
+All programs have a root scope named ``_`` which is by default
+assembled. This option allows another labelled target (either a
+[[asm-dialect-scope]] or a [[asm-dialect-datasegment]] to be
+assembled instead. The entire program is still assembled per usual,
+so this only impacts which part of the program is output.
+
+_subsection: Disassembler Examples
+
+A disassembled program shows offsets and mnemonics for the given
+bytecode. This format may change in the future to be more
+human-readable.

+_subsection: BigNumber
+
+_heading: Namespace
+Since [[bignumber]] is used quite frequently, it has been moved to
+the top level of the umbrella package.
+_code: bignumber-namespace.txt
+
+_heading: Creating Instances
+The ``bigNumberify`` method was always preferred over the constructor
+since it could short-circuit an object instantiation for [[bignumber]
+objects (since they are immutable). This has been moved to a static
+``from`` class method.
+_code: bignumber-creating.txt
+
+
+_subsection: Contracts
+_code: contracts.txt
+
+_subsection: Errors
+
+_heading: Namespace
+All errors now belong to the [[logger]] class and the related functions
+have been moved to [[logger]] instances, which can include a per-package
+version string.
+
+Global error fucntions have been moved [[logger]] class methods.
+_code: errors.txt
+
+
+_subsection: Interface
+The [[abi-interface]] object has undergone the most dramatic changes.
+
+It is no longer a meta-class and now has methods that simplify handling
+contract interface operations without the need for object inspection and
+special edge cases.

+_heading: Functions
+_code: interface-functions.txt

+Utilities
+=========
+
+
+
+Assembler
+---------
+
+
+The assembler utilities allow parsing and assembling an
+[Ethers ASM Dialect](../dialect) source file.
+
+
+#### *asm* . **parse** ( code )  **=>** *[Node](../ast)*
+
+Parse an ethers-format assembly file and return the [Abstract Syntax Tree](../ast).
+
+
+
+
+#### *asm* . **assemble** ( node )  **=>** *string< [DataHexstring](../../../utils/bytes) >*
+
+Performs assembly of the [Abstract Syntax Tree](../ast) *node* and return the
+resulting bytecode representation.
+
+
+
+
+Disassembler
+------------
+
+
+The **Disassembler** utilities make it easy to convert bytecode
+into an object which can easily be examined for program structure.
+
+
+#### *asm* . **disassemble** ( bytecode )  **=>** *[Bytecode](./)*
+
+Returns an array of Operations given *bytecode*.
+
+
+
+
+#### *asm* . **formatBytecode** ( operations )  **=>** *string*
+
+Create a formatted output of an array of [Operation](./).
+
+
+
+
+### Bytecode
+
+
+Each arary index represents an operation, collapsing multi-byte operations
+(i.e. `PUSH`) into a single operation.
+
+
+#### *bytecode* . **getOperation** ( offset )  **=>** *[Operation](./)*
+
+Get the operation at a given *offset* into the bytecode. This ensures that
+the byte at *offset* is an operation and not data contained within a `PUSH`,
+in which case null it returned.
+
+
+
+
+### Operation
+
+
+An **Operation** is a single command from a disassembled bytecode
+stream.
+
+
+#### *operation* . **opcode** **=>** *[Opcode](./)*
+
+The opcode for this Operation.
+
+
+
+
+#### *operation* . **offset** **=>** *number*
+
+The offset into the bytecode for this Operation.
+
+
+
+
+#### *operation* . **pushValue** **=>** *string< [DataHexstring](../../../utils/bytes) >*
+
+If the opcode is a `PUSH`, this is the value of that push
+
+
+
+
+Opcode
+------
+
+
+
+#### *asm* . *Opcode* . **from** ( valueOrMnemonic )  **=>** *[Opcode](./)*
+
+Create a new instnace of an Opcode for a given numeric value
+(e.g. 0x60 is PUSH1) or mnemonic string (e.g. "PUSH1").
+
+
+
+
+### Properties
+
+
+
+#### *opcode* . **value** **=>** *number*
+
+The value (bytecode as a number) of this opcode.
+
+
+
+
+#### *opcode* . **mnemonic** **=>** *string*
+
+The mnemonic string of this opcode.
+
+
+
+
+#### *opcode* . **delta** **=>** *number*
+
+The number of items this opcode will consume from the stack.
+
+
+
+
+#### *opcode* . **alpha** **=>** *number*
+
+The number of items this opcode will push onto the stack.
+
+
+
+
+#### *opcode* . **doc** **=>** *string*
+
+A short description of what this opcode does.
+
+
+
+
+#### *opcode* . **isMemory** (  )  **=>** *"read"|"write"|"full"*
+
+Returns true if the opcode accesses memory.
+
+
+
+
+#### *opcode* . **isStatic** (  )  **=>** *boolean*
+
+Returns true if the opcode cannot change state.
+
+
+
+
+#### *opcode* . **isJump** (  )  **=>** *boolean*
+
+Returns true if the opcode is a jumper operation.
+
+
+
+
+#### *opcode* . **isPush** (  )  **=>** *number*
+
+Returns 0 if the opcode is not a `PUSH*`, or the number
+of bytes this opcode will push if it is.

+
+Abstract Syntax Tree
+====================
+
+
+Parsing a file using the [Ethers ASM Dialect](../dialect) will
+generate an Abstract Syntax Tree. The root node will always
+be a [ScopeNode](./) whose name is `_`.
+
+To parse a file into an Abstract Syntax tree, use the [parse](../api)
+function.
+
+
+Types
+-----
+
+
+
+### Location
+
+
+
+#### **offset** **=>** *number*
+
+The offset into the source code to the start of this node.
+
+
+
+
+#### **length** **=>** *number*
+
+The length of characters in the source code to the end of this node.
+
+
+
+
+#### **source** **=>** *string*
+
+The source code of this node.
+
+
+
+
+Nodes
+-----
+
+
+@TODO: Place a diagram here showing the hierarchy
+
+
+### Node
+
+
+
+#### *node* . **tag** **=>** *string*
+
+A unique tag for this node for the lifetime of the process.
+
+
+
+
+#### *node* . **location** **=>** *[Location](./)*
+
+The source code and location within the source code that this
+node represents.
+
+
+
+
+### ValueNode
+
+
+A **ValueNode** is a node which may manipulate the stack.
+
+
+### LiteralNode
+
+
+
+#### *literalNode* . **value** **=>** *string*
+
+The literal value of this node, which may be a [DataHexstring](../../../utils/bytes) or
+string of a decimal number.
+
+
+
+
+#### *literalNode* . **verbatim** **=>** *boolean*
+
+This is true in a [DataNode](./) context, since in that case the
+value should be taken verbatim and no `PUSH` operation shoud be
+added, otherwise false.
+
+
+
+
+### PopNode
+
+
+A **PopNode** is used to store a place-holder for an implicit pop from the
+stack. It represents the code for an implicit place-holder (i.e. `$$`) or an
+explicit place-holder (e.g. `$1`), which indicates the expect stack position
+to consume.
+
+
+#### *literalNode* . **index** **=>** *number*
+
+The index this **PopNode** is representing. For an implicit place-holder
+this is `0`.
+
+
+
+
+### LinkNode
+
+
+A **LinkNode** represents a link to another [Node](./)'s data,
+for example `$foo` or `#bar`.
+
+
+#### *linkNode* . **label** **=>** *string*
+
+Te name of the target node.
+
+
+
+
+#### *linkNode* . **type** **=>** *"offset"|"length"*
+
+Whether this node is for an offset or a length value of the
+target node.
+
+
+
+
+### OpcodeNode
+
+
+
+#### *opcodeNode* . **opcode** **=>** *[Opcode](../api)*
+
+The opcode for this Node.
+
+
+
+
+#### *opcodeNode* . **operands** **=>** *Array< [ValueNode](./) >*
+
+A list of all operands passed into this Node.
+
+
+
+
+### EvaluationNode
+
+
+An **EvaluationNode** is used to execute code and insert the results
+but does not generate
+any output assembly, using the `{{! code here }}` syntax.
+
+
+#### *literalNode* . **verbatim** **=>** *boolean*
+
+This is true in a [DataNode](./) context, since in that case the
+value should be taken verbatim and no `PUSH` operation shoud be
+added, otherwise false.
+
+
+
+
+#### *evaluationNode* . **script** **=>** *string*
+
+The code to evaluate and produce the result to use as a literal.
+
+
+
+
+### ExecutionNode
+
+
+An **ExecutionNode** is used to execute code but does not generate
+any output assembly, using the `{{! code here }}` syntax.
+
+
+#### *evaluationNode* . **script** **=>** *string*
+
+The code to execute. Any result is ignored.
+
+
+
+
+### LabelledNode
+
+
+A **LabelledNode** is used for any Node that has a name, and can therefore
+be targetted by a [LinkNode](./).
+
+
+#### *labelledNode* . **name** **=>** *string*
+
+The name of this node.
+
+
+
+
+### LabelNode
+
+
+A **LabelNode** is used as a place to `JUMP` to by referencing it
+name, using `@myLabel:`. A `JUMPDEST` is automatically inserted
+at the bytecode offset.
+
+
+### DataNode
+
+
+A **DataNode** allows for data to be inserted directly into the output
+assembly, using `@myData[ ... ]`. The data is padded if needed to ensure
+values that would otherwise be regarded as a `PUSH` value does not impact
+anything past the data.
+
+
+#### *dataNode* . **data** **=>** *Array< [ValueNode](./) >*
+
+The child nodes, which each represent a verbatim piece of data in insert.
+
+
+
+
+### ScopeNode
+
+
+A **ScopeNode** allows a new frame of reference that all [LinkNode](./)'s
+will use when resolving offset locations, using `@myScope{ ... }`.
+
+
+#### *scopeNode* . **statements** **=>** *Array< [Node](./) >*
+
+The list of child nodes for this scope.
+

+Ethers ASM Dialect
+==================
+
+
+This provides a quick, high-level overcview of the **Ethers ASM Dialect**
+for EVM, which is defined by the [Ethers ASM Dialect Grammar](../../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethers-io/ethers.js/blob/ethers-v5-beta/packages/asm/grammar.jison)
+
+Once a program is compiled by a higher level langauge into ASM (assembly),
+or hand-coded directly in ASM, it needs to be assembled into bytecode.
+
+The assembly process performs a very small set of operations and is
+intentionally simple and closely related to the underlying EVM bytecode.
+
+Operations include embedding programs within programs (for example the
+deployment bootstrap has the runtime embedded in it) and computing the
+necessary offsets for jump operations.
+
+The [Command-Line Assembler](../../../../cli/asm) can be used to assemble an
+*Ethers ASM Dialect* file or to disassemble bytecode into its
+human-readable (ish) opcodes and literals.
+
+
+Opcodes
+-------
+
+
+An **Opcode** may be provided in either a *functional* or
+*instructional* syntax. For Opcodes that require parameters,
+the *functional* syntax is recommended and the *instructional*
+syntax will raise a warning.
+
+@TODO: Examples
+
+
+Labels
+------
+
+
+A **Label** is a position in the program which can be jumped to. A
+`JUMPDEST` is automatically added to this point in the assembled
+output.
+
+@TODO: Exmaples
+
+
+Literals
+--------
+
+
+A **Literal** puts data on the stack when executed using a `PUSH`
+operation.
+
+A **Literal** can be provided using a [DataHexstring](../../../utils/bytes) or a decimal
+byte value.
+
+@TODO: exmples
+
+
+Comments
+--------
+
+
+To enter a comment in the **Ethers ASM Dialect**, any text following
+a semi-colon (i.e. `;`) is ignored by the assembler.
+
+
+Scopes
+------
+
+
+A common case in Ethereum is to have one program embedded in another.
+
+The most common use of this is embedding a Contract **runtime bytecode**
+within a **deployment bytecode**, which can be used as **init code**.
+
+When deploying a program to Ethereum, an **init transaction** is used. An
+*init transaction* has a null `to` address and contains bytecode in
+the `data`. This `data` bytecode is a program, that when executed
+returns some other bytecode as a result, this restul is the bytecode
+to be installed.
+
+Therefore it is important that embedded code uses jumps relative to itself,
+not the entire program it is embedded in, which also means that a jump
+can **only** target its own scope, no parent or child scopes. This is
+enforced by the assembler.
+
+A scope may access the offset of any child [Data Segment](./) or
+child [Scopes](./) (with respect to itself) and may access the length
+of any [Data Segment](./) or [Scopes](./) anywhere in the program.
+
+Every program in the **Ethers ASM Dialect** has a top-leve scope named `_`.
+
+
+Data Segment
+------------
+
+
+A **Data Segment** allows arbitrary data to be embedded into a program,
+which can be useful for lookup tables or deploy-time constants.
+
+An emtpty **Data Segment** can also be used when a labelled location is
+required, but without the `JUMPDEST` which a [Labels](./) adds.
+
+@TODO: Example
+
+
+Links
+-----
+
+
+A **Link** allows access to a [Scopes](./), [Data Segment](./) or [Labels](./).
+
+To access the byte offset of a labelled item, use `$foobar`.
+
+For a [Labels](./), the target must be directly reachable within this scope. For
+a [Data Segment](./) or a [Scopes](./), it can be inside the same scope or any
+child scope.
+
+For a [Data Segment](./) or a [Labels](./), there is an additional type of
+**Link**, which provides the length of the data or bytecode respectively. A
+**Length Link** is accessed by `#foobar` and is pushed on the stack as a
+literal.

+<p>A common case in Ethereum is to have one program embedded in another.</p><p>The most common use of this is embedding a Contract <b>runtime bytecode</b> within a <b>deployment bytecode</b>, which can be used as <b>init code</b>.</p><p>When deploying a program to Ethereum, an <b>init transaction</b> is used. An <i>init transaction</i> has a null <code class="inline">to</code> address and contains bytecode in the <code class="inline">data</code>. This <code class="inline">data</code> bytecode is a program, that when executed returns some other bytecode as a result, this restul is the bytecode to be installed.</p><p>Therefore it is important that embedded code uses jumps relative to itself, not the entire program it is embedded in, which also means that a jump can <b>only</b> target its own scope, no parent or child scopes. This is enforced by the assembler.</p><p>A scope may access the offset of any child <a href="/api/other/assembly/dialect/#asm-dialect-datasegment">Data Segment</a> or child <a href="/api/other/assembly/dialect/#asm-dialect-scope">Scopes</a> (with respect to itself) and may access the length of any <a href="/api/other/assembly/dialect/#asm-dialect-datasegment">Data Segment</a> or <a href="/api/other/assembly/dialect/#asm-dialect-scope">Scopes</a> anywhere in the program.</p><p>Every program in the <b>Ethers ASM Dialect</b> has a top-leve scope named <code class="inline">_</code>.</p>

+Hardware Wallets
+================
+
+
+
+LedgerSigner
+------------
+
+
+The [Ledger Hardware Wallets](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/www.ledger.com) are a fairly
+popular brand.
+
+TODO: importing
+
+
+### API
+
+
+
+#### **new** **LedgerSigner** (  [ provider [  , type [  , path ]  ]  ]  )  **=>** *[LedgerSigner](./)*
+
+Connects to a Ledger Hardware Wallet. The *type* if left unspecified is
+determined by the environment; in node the default is "hid" and in the browser
+"u2f" is the default. The default Ethereum path is used if *path* is left unspecified.

 <p>There are many services which offer a web API for accessing the Ethereum Blockchain. These Providers allow connecting to them, which simplifies development, since you do not need to run your own instance or cluster of Ethereum nodes.</p><p>However, this reliance on third-party services can reduce resiliance, security and increase the amount of required trust. To mitigate these issues, it is recommended you use a <a href="/api/providers/#get-default-provider">Default Provider</a>.</p>

 JsonRpcUncheckedSigner
 ----------------------
 
 
-TODO... Explain
+The JSON-RPC API only provides a transaction hash as the response when a
+transaction is sent, but the ethers Provider requires populating all details
+of a transaction before returning it. For example, the gas price and gas limit
+may be adjusted by the node or the nonce automatically included, in which case
+the opaque transaction hash has discarded this.
+
+To remedy this, the [JsonRpcSigner](./) immeidately queries the provider for
+the details using the returned transaction hash to populate the [TransactionResponse](../types)
+object.
+
+Some backends do not respond immediately and instead defer releasing the
+details of a transaction it was responsible for signing until it is mined.
+
+The **UncheckedSigner** does not populate any additional information and will
+immediately return the result as a mock [TransactionResponse](../types)-like
+object, with most of the properties set to null, but allows access to the
+transaction hash quickly, if that is all that is required.

 ----------------
 
 
-Explain...
+The **FallbackProvider** is the most advanced [Provider](../provider) available in
+ethers.
 
+It uses a quorum and connects to multiple [Providers](../provider) as backends,
+each configured with a *priority* and a *weight* .
 
-### Properties
+When a request is made, the request is dispatched to multiple backends, randomly
+choosen (higher prioirty backends are always selected first) and the results from
+each are compared against the others. Only once the quorum has been reached will that
+result be accepted and returned to the caller.
 
+By default the quorum requires 50% (rounded up) of the backends to agree. The *weight*
+can be used to give a backend Provider more influence.

+If a [Provider](../provider) is provided, the defaults are a priority of 1 and a weight of 1.

-Explain...
+The **IpcProvider** allows the JSON-RPC API to be used over a local
+filename on the file system, exposed by Geth, Parity and other nodes.
+
+This is only available in *node.js* (as it requires file system access,

+
+UrlJsonRpcProvider
+------------------
+
+
+This class is intended to be sub-classed and not used directly. It
+simplifies creating a [Provider](../provider) where a normal [JsonRpcProvider](../jsonrpc-provider)
+would suffice, with a little extra effort needed to generate the JSON-RPC
+URL.
+
+
+#### **new** *ethers* . *providers* . **UrlJsonRpcProvider** (  [ network [  , apiKey ]  ]  )

+
+The value of the apiKey that was returned from `InheritedClass.getApiKey`.
+
+
+

+#### *InheritingClass* . **getApiKey** ( apiKey )  **=>** *any*
+
+This function should examine the *apiKey* to ensure it is valid and

+Web3Provider
+------------
+
+
+The Web3Provider is meant to ease moving from a [web3.js based](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethereum/web3.js)
+application to ethers by wraping an existing Web3-compatible (such as a
+[Web3HttpProvider](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethereum/web3.js/tree/1.x/packages/web3-providers-http)[Web3IpcProvider](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethereum/web3.js/tree/1.x/packages/web3-providers-ipc) or
+[Web3WsProvider](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethereum/web3.js/tree/1.x/packages/web3-providers-ws)) and exposing it as an ethers.js [Provider](../provider)
+which can then be used with the rest of the library.
+
+
+#### **new** *ethers* . *providers* . **Web3Provider** ( web3Provider [  , network ]  )

 Transactions
@@ -99,33 +323,263 @@ Transactions
 A transaction request describes a transaction that is to
 be sent to the network or otherwise processed.
 
-It contains the fields: 
-
-* **to** --- target address
-* **from** --- target address
-* **nonce** --- target address
-* **gasLimit** --- target address
-* **gasPrice** --- target address
-* **data** --- target address
-* **value** --- target address
-* **chainId** --- target address
-
 All fields are optional and may be a promise which resolves
 to the required type.
 
 
+#### *transactionRequest* . **to** **=>** *string|Promise< string >*
+
+The address (or ENS name) this transaction it to.
+
+
+
+
+#### *transactionRequest* . **from** **=>** *string< [Address](../../utils/address) >|Promise< string< [Address](../../utils/address) > >*
+
+The address this transaction is from.
+
+
+
+
+#### *transactionRequest* . **nonce** **=>** *number|Promise< number >*
+
+The nonce for this transaction. This should be set to the number of
+transactions ever sent **from** this address.
+
+
+
+
+#### *transactionRequest* . **gasLimit** **=>** *[BigNumber](../../utils/bignumber)|Promise< [BigNumber](../../utils/bignumber) >*
+
+The maximum amount of gas this transaction is permitted to use.
+
+
+
+
+#### *transactionRequest* . **gasPrice** **=>** *[BigNumber](../../utils/bignumber)|Promise< [BigNumber](../../utils/bignumber) >*
+
+The price (in wei) per unit of gas this transaction will pay.
+
+
+
+
+#### *transactionRequest* . **data** **=>** *[DataHexstring](../../utils/bytes)|Promise< [DataHexstring](../../utils/bytes) >*
+
+The transaction data.
+
+
+
+
+#### *transactionRequest* . **value** **=>** *[BigNumber](../../utils/bignumber)|Promise< [BigNumber](../../utils/bignumber) >*
+
+The amount (in wei) this transaction is sending.
+
+
+
+
+#### *transactionRequest* . **chainId** **=>** *number|Promise< number >*
+
+The chain ID this transaction is authorized on, as specified by
+[EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155).
+
+If the chain ID is 0 will disable EIP-155 and the transaction will be valid
+on any network. This can be **dangerous** and care should be taken, since it
+allows transactions to be replayed on networks that were possibly not
+intended.

+The timestamp of the block this transaction was mined in. If the block has not been mined,
+this is `null`.
+
+
+
+
+#### *transaction* . **confirmations** **=>** *number*
+
+The number of blocks that have been mined (including the initial block) since this
+transaction was mined.
+
+
+
+
+#### *transaction* . **raw** **=>** *string< [DataHexstring](../../utils/bytes) >*
+
+The serialized transaction.
+
+
+
+
+#### *transaction* . **wait** (  [ confirmations=1 ]  )  **=>** *Promise< [TransactionReceipt](./) >*
+
+Wait for *confirmations*. If 0, and the transaction has not been mined,
+`null` is returned.
+
+
 
 
 ### TransactionReceipt
 
 
-TODO
+
+#### *receipt* . **to** **=>** *string< [Address](../../utils/address) >*
+
+The address this transaction is to. This is `null` if the the
+transaction was an **init transaction**, used to deploy a contract.
+
+
+
+
+#### *receipt* . **from** **=>** *string< [Address](../../utils/address) >*
+
+The address this transaction is from.
+
+
+
+
+#### *receipt* . **contractAddress** **=>** *string< [Address](../../utils/address) >*
+
+If this transaction has a ``null` to address, it is an **init transaction**
+used to deploy a contract, in which case this is the address created by that
+contract.
+
+To compute a contract address, the [getContractAddress](../../utils/address)
+utility function can also be used with a [TransactionResponse](./)
+object, which requires the transaction nonce and the address of the sender.
+
+
+
+
+#### *receipt* . **transactionIndex** **=>** *number*
+
+The index of this transaction in the list of transactions included in
+the block this transaction was mined in.
+
+
+
+
+#### *receipt* . **root** **=>** *string*
+
+The intermediate state root of a receipt.
+
+Only transactions included in blocks **before** the [Byzantium Hard Fork](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-609)
+have this property, as it was replaced by the `status` property.
+
+The property is generally of little use to developers. At the time
+it could be used to verify a state transition with a fraud-proof
+only considering the single transaction; without it the full block
+must be considered.
+
+
+
+
+#### *receipt* . **gasUsed** **=>** *[BigNumber](../../utils/bignumber)*
+
+The amount of gas actually used by this transaction.
+
+
+
+
+#### *receipt* . **logsBloom** **=>** *string< [DataHexstring](../../utils/bytes) >*
+
+A [bloom-filter](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/Bloom_filter), which
+incldues all the addresses and topics included in any log in this
+transaction.
+
+
+
+
+#### *receipt* . **blockHash** **=>** *string< [DataHexstring](../../utils/bytes)< 32 > >*
+
+The block hash of the block that this transaction was included in.
+
+
+
+
+#### *receipt* . **transactionHash** **=>** *string< [DataHexstring](../../utils/bytes)< 32 > >*
+
+The transaction hash of this transaction.
+
+
+
+
+#### *receipt* . **logs** **=>** *Array< [Log](./) >*
+
+All the logs emitted by this transaction.
+
+
+
+
+#### *receipt* . **blockNumber** **=>** *number*
+
+The block height (number) of the block that this transaction was
+included in.
+
+
+
+
+#### *receipt* . **confirmations** **=>** *number*
+
+The number of blocks that have been mined since this transaction,
+including the actual block it was mined in.
+
+
+
+
+#### *receipt* . **cumulativeGasUsed** **=>** *[BigNumber](../../utils/bignumber)*
+
+For the block this transaction was included in, this is the sum of the
+gas used used by each transaction in the ordered list of transactions
+up to (and including) this transaction.
+
+This is generally of little interest to developers.
+
+
+
+
+#### *receipt* . **byzantium** **=>** *boolean*
+
+This is true if the block is in a [post-Byzantium Hard Fork](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-609)
+block.
+
+
+
+
+#### *receipt* . **status** **=>** *boolean*
+
+The status of a transaction is 1 is successful or 0 if it was
+reverted. Only transactions included in blocks [post-Byzantium Hard Fork](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-609)
+have this property.

+
+
+
+
+#### *signer* . **estimateGas** ( transactionRequest )  **=>** *Promise< [BigNumber](../utils/bignumber) >*

+
+
+
+
+### Signing
+
+
+
+#### *signer* . **signMessage** ( message )  **=>** *Promise< string< [FlatSignature](../utils/bytes) > >*
+
+This returns a Promise which resolves to the [Flat-Format Signature](../utils/bytes)
+of *message*.
+
+Sub-classes **must** implement this, however they may throw if signing a
+message is not supported.
+
+
+
+
+#### Note
+
+If *message* is a string, it is **treated as a string** and
+converted to its representation in UTF8 bytes.
+
+**If and only if** a message is a [Bytes](../utils/bytes) will it be treated as
+binary data.
+
+For example, the string `"0x1234"` is 6 characters long (and in
+this case 6 bytes long). This is **not** equivalent to the array
+`[ 0x12, 0x34 ]`, which is 2 bytes long.
+
+A common case is to sign a hash. In this case, if the hash is a
+string, it **must** be converted to an array first, using the
+[arrayify](../utils/bytes) utility function.
+
+
+
+
+
+#### *signer* . **signTransaction** ( transactionRequest )  **=>** *Promise< string< [DataHexstring](../utils/bytes) > >*
+
+Returns a Promise which resolves to the signed transaction of the
+*transactionRequest*. This method does not populate any missing fields.
+
+Sub-classes **must** implement this, however they may throw if signing a
+transaction is not supported.
+
+
+
+
+#### *signer* . **sendTransaction** ( transactionRequest )  **=>** *Promise< [TransactionResponse](../providers/types) >*
+
+This method populates the transactionRequest with missing fields, using
+[populateTransaction](./) and returns a Promise which resolves to the transaction.
+
+Sub-classes **must** implement this, however they may throw if signing a
+transaction is not supported.
+
+
+
+
+### Sub-Classes
+
+
+It is very important that all important properties of a **Signer** are
+**immutable**. Since Ethereum is very asynchronous and deals with critical
+data (such as ether and other potentially valuable crypto assets), keeping
+properties such as the *provider* and *address* static helps prevent
+serious issues.
+
+A sub-class **must** call `super()`.
+
+
+#### *signer* . **checkTransaction** ( transactionRequest )  **=>** *[TransactionRequest](../providers/types)*
+
+This is generally not required to be overridden, but may needed to provide
+custom behaviour in sub-classes.
+
+This should return a **copy** of the *transactionRequest*, with any properties
+needed by `call`, `estimateGas` and `populateTransaction` (which is used
+by sendTransaction). It should also throw an error if any unknown key is specified.
+
+The default implementation checks only valid [TransactionRequest](../providers/types) properties
+exist and adds `from` to the transaction if it does not exist, or verifies it is equal
+to the Signer's address if it does exist.
+
+
+
+
+#### *signer* . **populateTransaction** ( transactionRequest )  **=>** *Promise< [TransactionRequest](../providers/types) >*
+
+This is generally not required to be overridden, but may needed to provide
+custom behaviour in sub-classes.
+
+This should return a **copy** of *transactionRequest*, follow the same procedure
+as `checkTransaction` and fill in any properties required for sending a transaction.
+The result should have all promises resolved; if needed the [resolveProperties](../utils/properties)
+utility function can be used for this.
+
+The default implementation calls `checkTransaction` and resolves to if it is an
+ENS name, adds `gasPrice`, `nonce`, `gasLimit` and `chainId` based on the
+related operations on Signer.
+
+
+
+
+Wallet
+------
 
 
 The Wallet class inherits [Signer](./) and can sign transactions and messages
 using a private key as a standard Externally Owned Account (EOA).
 
 
-### Creating an Instance
+#### **new** *ethers* . **Wallet** ( privateKey [  , provider ]  ) 
 
+Create a new Wallet instance for *privateKey* and optionally
+connected to the *provider*.
 
 
-#### **new** *ethers* . **Wallet** ( privateKey [  , provider ]  ) 
 
-TODO
+
+#### *ethers* . *Wallet* . **createRandom** (  [ options={} ]  )  **=>** *[Wallet](./)*
+
+Returns a new Wallet with a random private key, generated from
+cryptographically secure entropy sources. If the current environment
+does not have a secure entropy source, an error is thrown.
+
+
+
+
+#### *ethers* . *Wallet* . **fromEncryptedJson** ( json , password [  , progress ]  )  **=>** *Promise< [Wallet](./) >*
+
+Create an instance from an encrypted JSON wallet. If *progress*
+is provided it will be called during decryption with a value between 0 and
+1 indicating the progress towards completion.
+
+
+
+
+#### *ethers* . *Wallet* . **fromMnemonic** ( mnemonic [  , path ,  [ wordlist ]  ]  )  **=>** *[Wallet](./)*
+
+Create an instance from a mnemonic phrase.
+
+If path is not specified, the Ethereum default path is used (i.e. m/44'/60'/0'/0/0).
+
+If wordlist is not specified, the English Wordlist is used.
+
+
+
+
+### Properties
+
+
+
+#### *wallet* . **address** **=>** *string< [Address](../utils/address) >*
+
+The address for the account this Wallet represents.
+
+
+
+
+#### *wallet* . **provider** **=>** *[Provider](../providers/provider)*
+
+The provider this wallet is connected to, which will ge used for any [Blockchain Methods](./)
+methods. This can be null.
+
+
+
+
+#### Note
+
+A **Wallet** instance is immuatable, so if you wish to change the Provider, you
+may use the [connect](./) method to create a new instance connected
+to the desired provider.
+
+
+
+
+#### *wallet* . **publicKey** **=>** *string< [DataHexstring](../utils/bytes)< 65 > >*
+
+The uncompressed public key for this Wallet represents.
+
+
+
+
+### Methods
+
+
+
+#### *wallet* . **encrypt** ( password ,  [ options={} ,  [ progress ]  ]  )  **=>** *Promise< string >*
+
+Encrypt the wallet using *password* returning a Promise which resolves
+to a JSON wallet.
+
+
+
+
+VoidSigner
+----------
+
+
+A **VoidSigner** is a simple Signer which cannot sign.
+
+It is useful as a read-only signer, when an API requires a
+Signer as a parameter, but it is known only read-only operations
+will be carried.
+
+For example, the `call` operation will automatically have the
+provided address passed along during the execution.
+
+
+#### **new** *ethers* . **VoidSigner** ( address )  **=>** *[VoidSigner](./)*
+
+Create a new instance of a **VoidSigner** for *address*.
+
+
+
+
+#### *voidSigner* . **address** **=>** *string< [Address](../utils/address) >*
+
+The address of this **VoidSigner**.

+Application Binary Interface
+============================
+
+
+Explain an ABI.
+
+
+Formats
+-------
+
+
+
+### JSON String ABI (Solidity Output JSON)
+
+
+The **JSON ABI Format** is the format that is
+[output from the Solidity compiler](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/solidity.readthedocs.io/en/v0.6.0/using-the-compiler.html).
+
+A JSON serialized object is always a string, which represents an Array
+of Objects, where each Object has various properties describing the [Fragment](./) of the ABI.
+
+The deserialied JSON string (which is a normal JavaScript Object) may
+also be passed into any function which accepts a JSON String ABI.
+
+
+### Humanb-Readable ABI
+
+
+The Human-Readable ABI was
+
+[article](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/blog.ricmoo.com/human-readable-contract-abis-in-ethers-js-141902f4d917)
+
+
+### Output Formats
+
+
+Each [Fragment](./) and [ParamType](./) may be output using its `format`
+method.
+
+
+#### *utils* . *FragmentTypes* . **full** **=>** *string*
+
+This is a full human-readable string, including all parameter names, any
+optional modifiers (e.g. `indexed`, `public`, etc) and white-space
+to aid in human readabiliy.
+
+
+
+
+#### *utils* . *FragmentTypes* . **minimal** **=>** *string*
+
+This is similar to `full`, except with no unnecessary whitespace or parameter
+names. This is useful for storing a minimal string which can still fully
+reconstruct the original Fragment using [Fragment&thinsp;.&thinsp;from](./).
+
+
+
+
+#### *utils* . *FragmentTypes* . **json** **=>** *string*
+
+This returns a JavaScript Object which is safe to call `JSON.stringify`
+on to create a JSON string.
+
+
+
+
+#### *utils* . *FragmentTypes* . **sighash** **=>** *string*
+
+This is a minimal output format, which is used by Solidity when computing a
+signature hash or an event topic hash.
+
+
+
+
+#### Note
+
+The `sighash` format is **insufficient** to re-create the original [Fragment](./),
+since it discards modifiers such as indexed, anonymous, stateMutability, etc.
+
+
+
+
+Interface
+---------
+
+
+TODO
+
+
+Fragment
+--------
+
+
+An ABI is a collection of **Fragments**, where each fragment specifies:
+
+
+
+* An Event
+* A Function
+* A Constructor
+
+
+### Properties
+
+
+
+#### *fragment* . **name** **=>** *string*
+
+This is the name of the Event or Function. This will be null for
+a [ConstructorFragment](./).
+
+
+
+
+#### *fragment* . **type** **=>** *string*
+
+This is a string which indicates the type of the [Fragment](./). This
+will be one of:
+
+
+
+* `constructor`
+* `event`
+* `function`
+
+
+
+
+#### *fragment* . **inputs** **=>** *Array< [ParamType](./) >*
+
+This is an array of of each [ParamType](./) for the input parameters to
+the Constructor, Event of Function.
+
+
+
+
+### Methods

+
+
+
+ConstructorFragment
+-------------------
+
+
+
+### Properties
+
+
+
+#### *fragment* . **gas** **=>** *[BigNumber](../bignumber)*
+
+This is the gas limit that should be used during deployment. It may be
+null.
+
+
+
+
+#### *fragment* . **payable** **=>** *boolean*
+
+This is whether the constructor may receive ether during deployment as
+an endowment (i.e. msg.value != 0).
+
+
+
+
+#### *fragment* . **stateMutability** **=>** *string*
+
+This is the state mutability of the constructor. It can be any of:
+
+
+
+* `nonpayable`
+* `payable`
+
+
+
+
+### Methods

+EventFragment
+-------------
+
+
+
+### Properties
+
+
+
+#### *fragment* . **anonymous** **=>** *boolean*
+
+This is whether the event is anonymous. An anonymous Event does not inject its
+topic hash as topic0 when creating a log.
+
+
+

+
+FunctionFragment
+----------------
+
+
+
+### Properties
+
+
+
+#### *fragment* . **constant** **=>** *boolean*
+
+This is whether the function is constant (i.e. does not change state). This
+is true if the state mutability is `pure` or `view`.
+
+
+
+
+#### *fragment* . **stateMutability** **=>** *string*
+
+This is the state mutability of the constructor. It can be any of:
+
+
+
+* `nonpayable`
+* `payable`
+* `pure`
+* `view`
+
+
+
+
+#### *fragment* . **outputs** **=>** *Array< [ParamType](./) >*
+
+A list of the Function output parameters.
+

+
+ParamType
+---------
+
+
+The following examples will represent the Solidity parameter:
+
+`string foobar`
+
+
+### Properties
+
+
+
+#### *paramType* . **name** **=>** *string*
+
+The local parameter name. This may be null for unnamed parameters. For example,
+the parameter definition `string foobar` would be `foobar`.
+
+
+
+
+#### *paramType* . **type** **=>** *string*
+
+The full type of the parameter, including tuple and array symbols. This may be null
+for unnamed parameters. For the above example, this would be `foobar`.
+
+
+
+
+#### *paramType* . **basetype** **=>** *string*
+
+The base type of the parameter. For primitive types (e.g. `address`, `uint256`, etc)
+this is equal to [type](./). For arrays, it will be the string `array` and for
+a tuple, it will be the string `tuple`.
+
+
+
+
+#### *paramType* . **indexed** **=>** *boolean*
+
+Whether the parameter has been marked as indexed. This **only** applies
+to parameters which are part of an [EventFragment](./).
+
+
+
+
+#### *paramType* . **arrayChildren** **=>** *[ParamType](./)*
+
+The type of children of the array. This is null for for any parameter
+wjhich is not an array.
+
+
+
+
+#### *paramType* . **arrayLength** **=>** *number*
+
+The length of the array, or `-1` for dynamic-length arrays. This is
+null for parameters which is not arrays.
+
+
+
+
+#### *paramType* . **components** **=>** *Array< [ParamType](./) >*
+
+The components of a tuple. This is null for non-tuple parameters.

-#### *utils* . **getAddress** ( address )  **=>** *string*
+### Address
+
+
+An **Address** is a [DataHexstring](../bytes) of 20 bytes (40 nibbles), with optional
+mixed case.
+
+If the case is mixed, it is a **Checksum Address**, which uses a specific pattern
+of uppercase and lowercase letters within a given address to reduce the risk
+of errors introduced from typing an address or cut and paste issues.
+
+All functions that return an Address will return a Checksum Address.
+
+
+### ICAP Address
+
+
+The **ICAP Address Format** was an early attempt to introduce a checksum
+into Ethereum addresses using the popular banking industry's
+[IBAN](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/International_Bank_Account_Number)
+format with the country code specified as **XE**.
+
+Due to the way IBAN encodes address, only addresses that fit into 30 base-36
+characters are actually compatible, so the format was adapted to support 31
+base-36 characters which is large enough for a full Ethereum address, however
+the preferred method was to select a private key whose address has a `0` as
+the first byte, which allows the address to be formatted as a fully compatibly
+standard IBAN address with 30 base-36 characters.
+
+In general this format is no longer widely supported anymore, however any function that
+accepts an address can receive an ICAP address, and it will be converted internally.
+
+To convert an address into the ICAP format, see [getIcapAddress](./).

+<p>The <b>ICAP Address Format</b> was an early attempt to introduce a checksum into Ethereum addresses using the popular banking industry's <a href="https://en.wikipedia.org/wiki/International_Bank_Account_Number">IBAN</a> format with the country code specified as <b>XE</b>.</p><p>Due to the way IBAN encodes address, only addresses that fit into 30 base-36 characters are actually compatible, so the format was adapted to support 31 base-36 characters which is large enough for a full Ethereum address, however the preferred method was to select a private key whose address has a <code class="inline">0</code> as the first byte, which allows the address to be formatted as a fully compatibly standard IBAN address with 30 base-36 characters.</p><p>In general this format is no longer widely supported anymore, however any function that accepts an address can receive an ICAP address, and it will be converted internally.</p><p>To convert an address into the ICAP format, see <a href="/api/utils/address/#utils-getIcapAddress">getIcapAddress</a>.</p>

+### Why not BigNumber.js, BN.js, BigDecimal, etc?
+
+
+Everyone has their own favourite Big Number library, and once someone
+has choosen one, it becomes part of their identity, like their editor,
+vi vs emacs. There are over 100 Big Number libraries on [npm](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/www.npmjs.com/search?q=bignumber).
+
+One of the biggest differences between the Ethers [BigNumber](./) object and
+other libraries is that it is immutable, which is very important when
+dealing with the asynchronous nature of the blockchain.
+
+Capturing the value is not safe in async functions, so immutability
+protects us from easy to make mistakes, which is not possible on the
+low-level library's objects which supports myriad in-place operations.
+
+Second, the Ethers [BigNumber](./) provides all the functionality required
+internally and should generally be sufficient for most developers while
+not exposing some of the more advanced and rare functionality. So it will
+be eaiser to swap out the underlying library without impacting consumers.
+
+For example, if [BN.js](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/www.npmjs.com/package/bn.js) was exposed, someone may use the
+greatest-common-denominator functions, which would then be functionality
+the replacing library should also provide to ensure anyone depending on
+that functionality is not broken.
+
+
+### Why BN.js??
+
+
+The reason why [BN.js](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/www.npmjs.com/package/bn.js) is used internally as the big
+number is because that is the library used by [elliptic](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/www.npmjs.com/package/elliptic).
+
+Therefore it **must** be included regardless, so we leverage that
+library rather than adding another Big Number library, which would
+mean two different libraries offering the same functionality.
+
+This has saved about 85kb (80% of this library size) of library size
+over other libraries which include separate Big Number libraries for
+various purposes.
+
+
+### Why not allow us to set a global Big Number library?
+
+
+Another comment that comes up frequently is tha desire to specify a
+global user-defined Big Number library, which all functions would
+return.
+
+This becomes problematic since your code may live along side other
+libraries or code that use Ethers. In fact, even Ethers uses a lot
+of the public functions internally.
+
+If you, for example, used a library that used `a.plus(b)` instead
+of `a.add(b)`, this would break Ethers when it tries to compute
+fees internally, and other libraries likely have similar logic.
+
+But, the [BigNumber](./) prototype is exposed, so you can always add a
+`toMyCustomBigNumber()` method to all [BigNumber](./)'s globally
+which is safe.

+<p>Everyone has their own favourite Big Number library, and once someone has choosen one, it becomes part of their identity, like their editor, vi vs emacs. There are over 100 Big Number libraries on <a href="https://www.npmjs.com/search?q=bignumber">npm</a>.</p><p>One of the biggest differences between the Ethers <a href="/api/utils/bignumber/">BigNumber</a> object and other libraries is that it is immutable, which is very important when dealing with the asynchronous nature of the blockchain.</p><p>Capturing the value is not safe in async functions, so immutability protects us from easy to make mistakes, which is not possible on the low-level library's objects which supports myriad in-place operations.</p><p>Second, the Ethers <a href="/api/utils/bignumber/">BigNumber</a> provides all the functionality required internally and should generally be sufficient for most developers while not exposing some of the more advanced and rare functionality. So it will be eaiser to swap out the underlying library without impacting consumers.</p><p>For example, if <a href="https://www.npmjs.com/package/bn.js">BN.js</a> was exposed, someone may use the greatest-common-denominator functions, which would then be functionality the replacing library should also provide to ensure anyone depending on that functionality is not broken.</p>
+<a name="why-bn.js??"></a><h3 class="show-anchors"><div>Why BN.js??<div class="anchors"><a class="self" href="#why-bn.js??"></a></div></div></h3>
+<p>The reason why <a href="https://www.npmjs.com/package/bn.js">BN.js</a> is used internally as the big number is because that is the library used by <a href="https://www.npmjs.com/package/elliptic">elliptic</a>.</p><p>Therefore it <b>must</b> be included regardless, so we leverage that library rather than adding another Big Number library, which would mean two different libraries offering the same functionality.</p><p>This has saved about 85kb (80% of this library size) of library size over other libraries which include separate Big Number libraries for various purposes.</p>
+<a name="why-not-allow-us-to-set-a-global-big-number-library?"></a><h3 class="show-anchors"><div>Why not allow us to set a global Big Number library?<div class="anchors"><a class="self" href="#why-not-allow-us-to-set-a-global-big-number-library?"></a></div></div></h3>
+<p>Another comment that comes up frequently is tha desire to specify a global user-defined Big Number library, which all functions would return.</p><p>This becomes problematic since your code may live along side other libraries or code that use Ethers. In fact, even Ethers uses a lot of the public functions internally.</p><p>If you, for example, used a library that used <code class="inline">a.plus(b)</code> instead of <code class="inline">a.add(b)</code>, this would break Ethers when it tries to compute fees internally, and other libraries likely have similar logic.</p><p>But, the <a href="/api/utils/bignumber/">BigNumber</a> prototype is exposed, so you can always add a <code class="inline">toMyCustomBigNumber()</code> method to all <a href="/api/utils/bignumber/">BigNumber</a>'s globally which is safe.</p><div class="footer"><div class="nav previous"><a href="/api/utils/address/"><span class="arrow">&larr;</span>Addresses</a></div> <div class="nav next"><a href="/api/utils/bytes/">Byte Manipulation<span class="arrow">&rarr;</span></a></div></div><div class="copyright">The content of this site is licensed under the <a href="https://choosealicense.com/licenses/cc-by-4.0/">Creative Commons Attribution 4.0 International License</a>.</div></div><script src="/script.js" type="text/javascript"></script></body></html><!-- ContentHash:abd9a59ec935cdc797867d1a5d5c1ed0a30ec95d78a2981de15aa6e21cfdd917 -->

+Encoding Utilities
+==================
+
+
+
+Base58
+------
+
+
+
+#### *ethers* . *utils* . *base58* . **decode** ( textData )  **=>** *Uin8Array*
+
+Return a typed Uint8Array representation of *textData* decoded using
+base-58 encoding.
+
+
+
+
+#### *ethers* . *utils* . *base58* . **encode** ( aBytesLike )  **=>** *string*
+
+Return *aBytesLike* encoded as a string using the base-58 encoding.
+
+
+
+
+Base64
+------
+
+
+
+#### *ethers* . *utils* . *base64* . **decode** ( textData )  **=>** *Uin8Array*
+
+Return a typed Uint8Array representation of *textData* decoded using
+base-64 encoding.
+
+
+
+
+#### *ethers* . *utils* . *base64* . **encode** ( aBytesLike )  **=>** *string*
+
+Return *aBytesLike* encoded as a string using the base-64 encoding.
+
+
+
+
+Recursive-Length Prefix
+-----------------------
+
+
+The [Recursive Length Prefix](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/ethereum/wiki/wiki/RLP) encoding is used throughout Ethereum to serialize nested
+structures of Arrays and data.
+
+
+#### *ethers* . *utils* . *RLP* . **encode** ( dataObject )  **=>** *string< [DataHexstring](../bytes) >*
+
+Encode a structured Data Object into its RLP-encoded representation.
+
+Each Data component may be an valid [BytesLike](../bytes).
+
+
+
+
+#### *ethers* . *utils* . *RLP* . **decode** ( aBytesLike )  **=>** *[DataObject](./)*
+
+Decode an RLP-encoded *aBytesLike* into its structured Data Object.
+
+All Data components will be returned as a [DataHexstring](../bytes).
+
+
+
+
+### Data Object
+
+
+A **Data Object** is a recursive structure which is used to serialize many
+internal structures in Ethereum. Each **Data Object** can either be:
+
+
+
+* Binary Data
+* An Array of **Data Objects** (i.e. this recursively includes Nesting)
+
+
+#### **Examples**
+
+
+
+* `"0x1234"`
+* `[ "0x1234", [ "0xdead", "0xbeef" ], [ ] ]`

+FixedFormat
+-----------
+
+
+A **FixedFormat** is a simple object which represents a decimal
+(base-10) Fixed-Point data representation. Usually using this
+class directly is uneccessary, as passing in a [Format Strings](./)
+directly into the [FixedNumber](./) will automatically create this.
+
+
+### Format Strings
+
+
+A format string is composed of three components, including signed-ness,
+bit-width and number of decimals.
+
+A signed format string begins with `fixed`, which an unsigned format
+string begins with `ufixed`, followed by the width (in bits) and the
+number of decimals.
+
+The width must be conguent to 0 mod 8 (i.e. `(width % 8) == 0`) and no
+larger than 256 bits and the number of decimals must be no larger than 80.
+
+For example:
+
+
+
+* **fixed128x18** is signed, 128 bits wide and has 18 decimals; this is useful for most purposes
+* **fixed32x0** is signed, 32 bits wide and has 0 decimals; this would be the same as a ``int32_t` in C
+* **ufixed32x0** is unsigned, 32 bits wide and has 0 decimals; this would be the same as a ``uint32_t` in C
+* **fixed** is shorthand for ``fixed128x18`
+* **ufixed** is shorthand for ``ufixed128x18`
+
+
+### Creating Instances
+
+
+
+#### *FixedFormat* . **from** ( value="fixed128x18" )  **=>** *[FixedFormat](./)*
+
+Returns a new instance of a **FixedFormat** defined by *value*. Any valid [Format Strings](./)
+may be passed in as well as any object which has any of `signed`, `width` and `decimals`
+defined, including a [FixedFormat](./) object.
+
+
+
+
+### Properties
+
+
+
+#### *fixedFormat* . **signed** **=>** *boolean*
+
+The signed-ness of *fixedFormat*, true if negative values are supported.
+
+
+
+
+#### *fixedFormat* . **width** **=>** *number*
+
+The width (in bits) of *fixedFormat*.
+
+
+
+
+#### *fixedFormat* . **decimals** **=>** *number*
+
+The number of decimal points of *fixedFormat*.
+
+
+
+
+#### *fixedFormat* . **name** **=>** *string*
+
+The name of the *fixedFormat*, which can be used to recreate the format
+and is the string that the Solidity language uses to represent this format.
+
+
+
+
+#### ***"fixed"***
+
+A shorthand for `fixed128x80`.

+HD Wallet
+=========
+
+
+TODO: Explain [BIP32](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) [BIP-39](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.bitcoin.it/wiki/BIP_0039) and whatnot here...
+
+
+Types
+-----
+
+
+
+### Constants
+
+
+
+#### *ethers* . *utils* . **defaultPath** **=>** *"m/44'/60'/0'/0/0"*
+
+The default path for Ethereum in an HD Wallet
+
+
+
+
+### Mnemonic
+
+
+
+#### *mnemonic* . **phrase** **=>** *string*
+
+The mnemonic phrase for this mnemonic. It is 12, 15, 18, 21 or 24 words long
+and separated by the whitespace specified by the `locale`.
+
+
+
+
+#### *mnemonic* . **path** **=>** *string*
+
+The HD path for this mnemonic.
+
+
+
+
+#### *mnemonic* . **locale** **=>** *string*
+
+The language of the wordlist this mnemonic is using.
+
+
+
+
+HDNode
+------
+
+
+
+### Creating Instances
+
+
+
+#### *ethers* . *HDNode* . **fromMnemonic** ( phrase [  , password [  , wordlist ]  ]  )  **=>** *[HDNode](./)*
+
+Return the [HDNode](./) for *phrase* with the optional *password*
+and *wordlist*.
+
+
+
+
+#### *ethers* . *HDNode* . **fromSeed** ( aBytesLike )  **=>** *[HDNode](./)*
+
+Return the [HDNode](./) for the seed *aBytesLike*.
+
+
+
+
+#### *ethers* . *HDNode* . **fromExtendedKey** ( extendedKey )  **=>** *[HDNode](./)*
+
+Return the [HDNode](./) for the *extendedKey*. If *extendedKey* was
+neutered, the **HDNode** will only be able to compute addresses and not
+private keys.
+
+
+
+
+### Properties
+
+
+
+#### *hdNode* . **privateKey** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The private key for this HDNode.
+
+
+
+
+#### *hdNode* . **publicKey** **=>** *string< [DataHexstring](../bytes)< 33 > >*
+
+The (compresses) public key for this HDNode.
+
+
+
+
+#### *hdNode* . **fingerprint** **=>** *string< [DataHexstring](../bytes)< 4 > >*
+
+The fingerprint is meant as an index to quickly match parent and
+children nodes together, however collisions may occur and software
+should verify matching nodes.
+
+Most developers will not need to use this.
+
+
+
+
+#### *hdNode* . **parentFingerprint** **=>** *string< [DataHexstring](../bytes)< 4 > >*
+
+The fingerprint of the parent node. See *fingerprint* for more
+details.
+
+Most developers will not need to use this.
+
+
+
+
+#### *hdNode* . **address** **=>** *string< [Address](../address) >*
+
+The address of this HDNode.
+
+
+
+
+#### *hdNode* . **mnemonic** **=>** *[Mnemonic](./)*
+
+The mnemonic of this HDNode, if known.
+
+
+
+
+#### *hdNode* . **path** **=>** *string*
+
+The path of this HDNode, if known. If the *mnemonic* is also known,
+this will match `mnemonic.path`.
+
+
+
+
+#### *hdNode* . **chainCode** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The chain code is used as a non-secret private key which is then used
+with EC-multiply to provide the ability to derive addresses without
+the private key of child non-hardened nodes.
+
+Most developers will not need to use this.
+
+
+
+
+#### *hdNode* . **index** **=>** *number*
+
+The index of this HDNode. This will match the last component of
+the *path*.
+
+Most developers will not need to use this.
+
+
+
+
+#### *hdNode* . **depth** **=>** *number*
+
+The depth of this HDNode. This will match the number of components
+(less one, the `m/`) of the *path*.
+
+Most developers will not need to use this.
+
+
+
+
+#### *hdNode* . **extendedKey** **=>** *string*
+
+A serialized string representation of this HDNode. Not all properties
+are included in the serialization, such as the mnemonic and path, so
+serializing and deserializing (using the `fromExtendedKey` class
+method) will result in reduced information.
+
+
+
+
+### Methods
+
+
+
+#### *hdNode* . **neuter** (  )  **=>** *[HDNode](./)*
+
+Return a new instance of *hdNode* with its private key removed
+but all otehr properties preserved. This ensures that the key
+can not leak the private key of itself or any derived children,
+but may still be used to compute the addresses of itself and
+any non-hardened children.
+
+
+
+
+#### *hdNode* . **derivePath** ( path )  **=>** *[HDNode](./)*
+
+Return a new [HDNode](./) which is the child of *hdNode* found
+by deriving *path*.
+
+
+
+
+Other Functions
+---------------
+
+
+
+#### *ethers* . *utils* . **mnemonicToSeed** ( phrase [  , password ]  )  **=>** *string< [DataHexstring](../bytes)< 64 > >*
+
+Convert a mnemonic phrase to a seed, according to [BIP-39](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.bitcoin.it/wiki/BIP_0039).
+
+
+
+
+#### *ethers* . *utils* . **mnemonicToEntropy** ( phrase [  , wordlist ]  )  **=>** *string< [DataHexstring](../bytes) >*
+
+Convert a mnemonic phrase to its entropy, according to [BIP-39](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.bitcoin.it/wiki/BIP_0039).
+
+
+
+
+#### *ethers* . *utils* . **isValidMnemonic** ( phrase [  , wordlist ]  )  **=>** *boolean*
+
+Returns true if *phrase* is a valid mnemonic phrase, by
+testing the checksum.

+Logger
+======
+
+
+
+Errors
+------
+
+
+
+#### *Logger* . *errors* . **UNKNOWN_ERROR**
+
+A generic unknown error.
+
+
+
+
+#### *Logger* . *errors* . **NOT_IMPLEMENTED**
+
+The operation is not implemented.
+
+
+
+
+#### *Logger* . *errors* . **UNSUPPORTED_OPERATION**
+
+The operation is not supported.
+
+
+
+
+#### *Logger* . *errors* . **NETWORK_ERROR**
+
+An Ethereum network validation error, such as an invalid chain ID.
+
+
+
+
+#### *Logger* . *errors* . **SERVER_ERROR**
+
+There was an error communicating with a server.
+
+
+
+
+#### *Logger* . *errors* . **TIMEOUT**
+
+A timeout occurred.
+
+
+
+
+#### *Logger* . *errors* . **BUFFER_OVERRUN**
+
+The amount of data needed is more than the amount of data required,
+which would cause the data buffer to read past its end.
+
+
+
+
+#### *Logger* . *errors* . **NUMERIC_FAULT**
+
+There was an invalid operation done on numeric values.
+
+Common cases of this occur when there is [overflow](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/Integer_overflow),
+[arithmetic underflow](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/Arithmetic_underflow) in fixed numeric types or division by zero.
+
+
+
+
+#### *Logger* . *errors* . **MISSING_NEW**
+
+An object is a Class, but is now being called with `new`.
+
+
+
+
+#### *Logger* . *errors* . **INVALID_ARGUMENT**
+
+The type or value of an argument is invalid. This will generally also
+include the `name` and `value` of the argument. Any function which
+accepts sensitive data (such as a private key) will include the string
+`[REDACTED]]` instead of the value passed in.
+
+
+
+
+#### *Logger* . *errors* . **MISSING_ARGUMENT**
+
+An expected parameter was not specified.
+
+
+
+
+#### *Logger* . *errors* . **UNEXPECTED_ARGUMENT**
+
+Too many parameters we passed into a function.
+
+
+
+
+#### *Logger* . *errors* . **CALL_EXCEPTION**
+
+An attempt to call a blockchain contract (getter) resulted in a
+revert or other error.
+
+
+
+
+#### *Logger* . *errors* . **INSUFFICIENT_FUNDS**
+
+The account is attempting to make a transaction which costs more than is
+available.
+
+A sending account must have enough ether to pay for the value, the gas limit
+(at the gas price) as well as the intrinsic cost of data. The intrinsic cost
+of data is 4 gas for each zero byte and 68 gas for each non-zero byte.
+
+
+
+
+#### *Logger* . *errors* . **NONCE_EXPIRED**
+
+The nonce being specified has already been used in a mined transaction.
+
+
+
+
+#### *Logger* . *errors* . **REPLACEMENT_UNDERPRICED**
+
+When replacing a transaction, by using a nonce which has already been sent to
+the network, but which has not been mined yet the new transaction must specify
+a higher gas price.
+
+This error occurs when the gas price is insufficient to *bribe* the transaction
+pool to prefer the new transaction over the old one. Generally, the new gas price
+should be about 50% + 1 wei more, so if a gas price of 10 gwei was used, the
+replacement should be 15.000000001 gwei.
+
+
+
+
+#### *Logger* . *errors* . **UNPREDICTABLE_GAS_LIMIT**
+
+When estimating the required amount of gas for a transaction, a node is queried for
+its best guess.
+
+If a node is unable (or unwilling) to predict the cost, this error occurs.
+
+The best remedy for this situation is to specify a gas limit in the transaction
+manually.
+
+This error can also indicate that the transaction is expected to fail regardless,
+if for example an account with no tokens is attempting to send a token.
+
+
+
+
+Creating instances
+------------------
+
+
+
+#### **new** *ethers* . *utils* . **Logger** ( version ) 
+
+Create a new logger which will include *version* in all errors thrown.
+

+Signing Key
+===========
+
+
+
+#### **new** *ethers* . *utils* . **SigningKey** ( privateKey ) 
+
+Create a new SigningKey for *privateKey*.
+
+
+
+
+#### *signingKey* . **privateKey** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The private key for this Signing Key.
+
+
+
+
+#### *signingKey* . **publicKey** **=>** *string< [DataHexstring](../bytes)< 65 > >*
+
+The uncompressed public key for this Signing Key. It will always be
+65 bytes (130 nibbles) and begine with `0x04`.
+
+
+
+
+#### *signingKey* . **compressedPublicKey** **=>** *string< [DataHexstring](../bytes)< 33 > >*
+
+The compressed public key for this Signing Key. It will always be
+33 bytes (66 nibbles) and begine with either `0x02` or `0x03`.
+
+
+
+
+#### *signingKey* . **signDisgest** ( digest )  **=>** *[Signature](../bytes)*
+
+Sign the *digest* and return the signature.
+
+
+
+
+#### *signingKey* . **computeSharedSecret** ( otherKey )  **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+Compute the ECDH shared secret with *otherKey*. The *otherKey* may be
+either a public key or a private key, but generally will be a public key from
+another party.
+
+It is best practice that each party computes the hash of this before using it
+as a symmetric key.
+
+
+
+
+#### *SigningKey* . **isSigningKey** ( anObject )  **=>** *boolean*
+
+Returns true if *anObject* is a SigningKey.
+
+
+
+
+Other Functions
+---------------
+
+
+
+#### *ethers* . *utils* . **verifyMessage** ( message , signature )  **=>** *string< [Address](../address) >*
+
+Returns the address that signed *message* producing *signature*. The
+signature may have a non-canonical v (i.e. does not need to be 27 or 28),
+in which case it will be normalized to compute the `recoveryParam` which
+will then be used to compute the address; this allows systems which use
+the v to encode additional data (such as [EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155))
+to be used since the v parameter is still completely non-ambiguous.
+
+
+
+
+#### *ethers* . *utils* . **recocverPublicKey** ( digest , signature )  **=>** *string< [DataHexstring](../bytes)< 65 > >*
+
+
+
+
+
+
+#### *ethers* . *utils* . **computePublicKey** ( key [  , compressed=false ]  )  **=>** *string< [DataHexstring](../bytes) >*
+
+Computes the public key of *key*, optionally compressing it. The *key*
+can be any form of public key (compressed or uncompressed) or a private
+key.
+

+Custom UTF-8 Error Handling
+---------------------------
+
+
+When converting a string to its codepoints, there is the possibility
+of invalid byte sequences. Since certain situations may need specific
+ways to handle UTF-8 errors, a custom error handling function can be used,
+which has the signature:
+
+
+#### **errorFunction** ( reason , offset , bytes , output [  , badCodepoint ]  )  **=>** *number*
+
+The *reason* is one of the [UTF-8 Error Reasons](./), *offset* is the index
+into *bytes* where the error was first encountered, output is the list
+of codepoints already processed (and may be modified) and in certain Error
+Reasons, the *badCodepoint* indicates the currently computed codepoint,
+but which would be rejected because its value is invalid.
+
+This function should return the number of bytes to skip past keeping in
+mind the value at *offset* will already be consumed.
+
+
+
+
+### UTF-8 Error Reasons
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **BAD_PREFIX**
+
+A byte was encountered which is invalid to begin a UTF-8 byte
+sequence with.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **MISSING_CONTINUE**
+
+A UTF-8 sequence was begun, but did not have enough continuation
+bytes for the sequence. For this error the *ofset* is the index
+at which a continuation byte was expected.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **OUT_OF_RANGE**
+
+The computed codepoint is outside the range for valid UTF-8
+codepoints (i.e. the codepoint is greater than 0x10ffff).
+This reason will pass the computed *badCountpoint* into
+the custom error function.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **OVERLONG**
+
+Due to the way UTF-8 allows variable length byte sequences
+to be used, it is possible to have multiple representations
+of the same character, which means
+[overlong sequences](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/UTF-8)
+allow for a non-distinguished string to be formed, which can
+impact security as multiple strings that are otherwise
+equal can have different hashes.
+
+Generally, overlong sequences are an attempt to circumvent
+some part of security, but in rare cases may be produced by
+lazy libraries or used to encode the null terminating
+character in a way that is safe to include in a `char*`.
+
+This reason will pass the computed *badCountpoint* into the
+custom error function, which is actually a valid codepoint, just
+one that was arrived at through unsafe methods.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **OVERRUN**
+
+The string does not have enough characters remaining for the
+length of this sequence.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **UNEXPECTED_CONTINUE**
+
+This error is similar to BAD_PREFIX, since a continuation byte
+cannot begin a valid sequence, but many may wish to process this
+differently. However, most developers would want to trap this
+and perform the same operation as a BAD_PREFIX.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorReason* . **UTF16_SURROGATE**
+
+The computed codepoint represents a value reserved for
+UTF-16 surrogate pairs.
+This reason will pass the computed surrogate half
+*badCountpoint* into the custom error function.
+
+
+
+
+### Provided UTF-8 Error Handling Functions
+
+
+There are already several functions available for the  most common
+situations.
+
+
+#### *ethers* . *utils* . *Utf8ErrorFuncs* . **error**
+
+The will throw an error on **any** error with a UTF-8 sequence, including
+invalid prefix bytes, overlong sequences, UTF-16 surrogate pairs.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorFuncs* . **ignore**
+
+This will drop all invalid sequences (by consuming invalid prefix bytes and
+any following continuation bytes) from the final string as well as permit
+overlong sequences to be converted to their equivalent string.
+
+
+
+
+#### *ethers* . *utils* . *Utf8ErrorFuncs* . **replace**
+
+This will replace all invalid sequences (by consuming invalid prefix bytes and
+any following continuation bytes) with the
+[UTF-8 Replacement Character](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/Specials_%28Unicode_block%29),
+(i.e. U+FFFD).

+Transactions
+============
+
+
+
+Types
+-----
+
+
+
+### UnsignedTransaction
+
+
+An unsigned transaction represents a transaction that has not been
+signed and its values are flexible as long as they are not ambiguous.
+
+
+#### *unsignedTransaction* . **to** **=>** *string< [Address](../address) >*
+
+The addres this transaction is to.
+
+
+
+
+#### *unsignedTransaction* . **nonce** **=>** *number*
+
+The nonce of this transaction.
+
+
+
+
+#### *unsignedTransaction* . **gasLimit** **=>** *[BigNumberish](../bignumber)*
+
+The gas limit for this transaction.
+
+
+
+
+#### *unsignedTransaction* . **gasPrice** **=>** *[BigNumberish](../bignumber)*
+
+The gas price for this transaction.
+
+
+
+
+#### *unsignedTransaction* . **data** **=>** *[BytesLike](../bytes)*
+
+The data for this transaction.
+
+
+
+
+#### *unsignedTransaction* . **value** **=>** *[BigNumberish](../bignumber)*
+
+The value (in wei) for this transaction.
+
+
+
+
+#### *unsignedTransaction* . **chainId** **=>** *number*
+
+The chain ID for this transaction. If the chain ID is 0 or null,
+then [EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155) is disabled and legacy signing is
+used, unless overridden in a signature.
+
+
+
+
+### Transaction
+
+
+A generic object to represent a transaction.
+
+
+#### *transaction* . **hash** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The transaction hash, which can be used as an identifier for
+*transaction*. This is the keccak256 of the serialized RLP encoded
+representation of *transaction*.
+
+
+
+
+#### *unsignedTransaction* . **to** **=>** *string< [Address](../address) >*
+
+The address *transaction* is to.
+
+
+
+
+#### *transaction* . **from** **=>** *string< [Address](../address) >*
+
+The address *transaction* is from.
+
+
+
+
+#### *transaction* . **nonce** **=>** *number*
+
+The nonce for *transaction*. Each transaction sent to the network
+from an account includes this, which ensures the order and
+non-replayability of a transaction. This must be equal to the current
+number of transactions ever sent to the network by the **from** address.
+
+
+
+
+#### *transaction* . **gasLimit** **=>** *[BigNumber](../bignumber)*
+
+The gas limit for *transaction*. An account must have enough ether to
+cover the gas (at the specified **gasPrice**). Any unused gas is
+refunded at the end of the transaction, and if there is insufficient gas
+to complete execution, the effects of the trasaction are reverted, but
+the gas is **fully consumed** and an out-of-gas error occurs.
+
+
+
+
+#### *transaction* . **gasPrice** **=>** *[BigNumber](../bignumber)*
+
+The price (in wei) per unit of gas for *transaction*.
+
+
+
+
+#### *transaction* . **data** **=>** *[BytesLike](../bytes)*
+
+The data for *transaction*. In a contract this is the call data.
+
+
+
+
+#### *transaction* . **value** **=>** *[BigNumber](../bignumber)*
+
+The value (in wei) for *transaction*.
+
+
+
+
+#### *transaction* . **chainId** **=>** *number*
+
+The chain ID for *transaction*. This is used as part of
+[EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155) to prevent replay attacks on different
+networks.
+
+For example, if a transaction was made on ropsten with an account
+also used on homestead, it would be possible for a transaction
+signed on ropsten to be executed on homestead, which is likely
+unintended.
+
+There are situations where replay may be desired, however these
+are very rare and it is almost always recommended to specify the
+chain ID.
+
+
+
+
+#### *transaction* . **r** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The r portion of the elliptic curve signatures for *transaction*.
+This is more accurately, the x coordinate of the point r (from
+which the y can be computed, along with v).
+
+
+
+
+#### *transaction* . **s** **=>** *string< [DataHexstring](../bytes)< 32 > >*
+
+The s portion of the elliptic curve signatures for *transaction*.
+
+
+
+
+#### *transaction* . **v** **=>** *number*
+
+The v portion of the elliptic curve signatures for *transaction*.
+This is used to refine which of the two possible points a given
+x-coordinate can have, and in [EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155) is additionally
+used to encode the chain ID into the serialized transaction.
+
+
+
+
+Functions
+---------
+
+
+
+#### *ethers* . *utils* . **computeAddress** ( publicOrPrivateKey )  **=>** *string< [Address](../address) >*
+
+Compute the address of *publicOrPrivateKey*. If a public key is
+provided, it may be either compressed or uncompressed.
+
+
+
+
+#### *ethers* . *utils* . **parse** ( aBytesLike )  **=>** *[Transaction](./)*
+
+Parses the transaction properties from a serialized transactions.
+
+
+
+
+#### *ethers* . *utils* . **recoverAddress** ( digest , aSignatureLike )  **=>** *string< [Address](../address) >*
+
+Computes the address that signed *digest* to get *aSignatureLike* using the
+ecrecover algorithm.
+
+
+
+
+#### *ethers* . *utils* . **serialize** ( transaction [  , signature ]  )  **=>** *string< [DataHexstring](../bytes) >*
+
+Computes the serialized *transaction*, optionally serialized with
+the a *signature*. If *signature* is not present, the unsigned
+serialized transaction is returned, which can be used to compute the
+hash necessary to sign.
+
+This function uses [EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155) if a chainId is provided,
+otherwise legacy serialization is used. It is **highly** recommended
+to always specify a *chainId*.
+
+If *signature* includes a chain ID (explicitly or implicitly by using an
+[EIP-155](../../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/eips.ethereum.org/EIPS/eip-155) `v` or `_vs`) it will be used to compute the
+chain ID.
+
+If there is a mismatch between the chain ID of *transaction* and *signature*
+an error is thrown.

+Example Input Files
+-------------------
+
+
+
+#### **SimpleStore.asm**
+
+
+
+
+
+
+```
+; SimpleStore (uint)
+
+; Set the inital value of 42
+sstore(0, 42)
+
+; Init code to deploy myContract
+codecopy(0, $myContract, #myContract)

+    jumpi($error, callvalue)
+
+    ; Get the Sighash
+    shr({{= 256 - 32 }}, calldataload(0))
+
+    ; getValue()
+    dup1
+    {{= sighash("getValue()") }}
+    jumpi($getValue, eq)
+
+    ; setValue(uint)
+    dup1
+    {{= sighash("setValue(uint)") }}
+    jumpi($setValue, eq)
+
+    ; No matching signature
+    @error:
+        revert(0, 0)
+
+    @getValue:
+        mstore(0, sload(0))
+        return (0, 32)
+
+    @setValue:
+        ; Make sure we have exactly a uint
+        jumpi($error, iszero(eq(calldatasize, 36)))
+
+        ; Store the value
+        sstore(0, calldataload(4))
+        return (0, 0)
+
+    ; There is no *need* for the PUSH32, it just makes
+    ; decompiled code look nicer
+    @checksum[
+        {{= (defines.checksum ? concat([ Opcode.from("PUSH32"), id(myContract.source) ]): "0x") }}
+    ]
+}
+```
+
+
+
+#### **SimpleStore.bin**
+
+
+
+
+
+
+```
+0x602a6000556044601160003960446000f334601e5760003560e01c8063209652
+0x5514602457806355241077146030575b60006000fd5b60005460005260206000
+0xf35b6024361415601e5760043560005560006000f3
+```
+
+
+
+#### Note: Bytecode File Syntax
+
+A bin file may be made up of multiple blocks of bytecode, each may
+optionally begin with a `0x` prefix, all of which **must** be of
+even length (since bytes are required, with 2 nibbles per byte)
+
+All whitespace is ignored.
+
+
+
+
+Assembler Examples
+------------------
+
+
+The assembler converts an [Ethers ASM Dialect](../../api/other/assembly/dialect) into
+bytecode by running multiple passes of an assemble stage, each pass
+more closely approximating the final result.
+
+This allows small portions of the bytecode to be massaged and tweaked
+until the bytecode stablizes. This allows for more compact jump
+destinations and for code to be include more advanced meta-programming
+techniques.

+```
+
+
+
+### Options
+
+
+
+#### **--define KEY=VALUE** *or* **--define FLAG**
+
+This allows key/value pairs (where the value is a string) and
+flags (which the value is `true`) to be passed along to the
+assembler, which can be accessed in
+[Scripting Blocks](../../api/other/assembly/dialect), such as `{{= defined.someKey }}`.
+
+
+
+
+#### **--ignore-warnings**
+
+By default any warning will be treated like an error. This enabled
+by-passing warnings.
+
+
+
+
+#### **--pic**
+
+When a program is assembled, the labels are usually given as an
+absolute byte position, which can be jumped to for loops and
+control flow. This means that a program must be installed at a specific
+location.
+
+Byt specifying the **Position Independent Code** flag, code
+will be generated in a way such that all offsets are relative, allowing
+the program to be moved without any impact to its logic.
+
+This does incur an additional gsas cost of 8 gas per offset access though.
+
+
+
+
+#### **--target LABEL**
+
+All programs have a root scope named `_` which is by default
+assembled. This option allows another labelled target (either a
+[Scopes](../../api/other/assembly/dialect) or a [Data Segment](../../api/other/assembly/dialect) to be
+assembled instead. The entire program is still assembled per usual,
+so this only impacts which part of the program is output.
+
+
+
+
+Disassembler Examples
+---------------------
+
+
+A disassembled program shows offsets and mnemonics for the given
+bytecode. This format may change in the future to be more
+human-readable.

+Sandbox Utility
+===============
+
+
+The sandbox utility provides a simple way to use the most common
+ethers utilities required during learning, debuging and managing
+interactions with the Ethereum network.
+
+If no command is given, it will enter a REPL interface with many
+of the ethers utilities already exposed.

+
+
+
+### Scripting
+
+
+The `eval` command can be used to execute simple one-line scripts from
+the command line to be passed into other commands or stored in script
+environment variables.
+
+
+```
+# Get the formatted balance of an account
+/home/ethers> ethers --network ropsten --account wallet.json eval 'accounts[0].getBalance().then(b => formatEther(b))'
+3.141592653589793238
+
+# Get the current block number
+/home/ethers> ethers --network rinkeby eval "provider.getBlockNumber()"
+5761009
+
+# Convert a Solidity signature to JSON
+/home/ethers> ethers eval 'utils.Fragment.from("function balanceOf(address owner) view returns (uint)").format("json")' 
+{"type":"function","name":"balanceOf","constant":true,"stateMutability":"view","payble":false,"inputs":[{"type":"address","name":"owner"}],"ouputs":[{"type":"uint256"}]}
+
+# Compute a topic hash
+/home/ricmoo> ethers eval 'id("Transfer(address,address,uint256")'
+0xd99659a21de82e379975ce8df556f939a4ccb95e92144f38bb0dd35730ffcdd5
+
+# Create a random mnemonic
+/home/ricmoo> ethers eval 'Wallet.createRandom().mnemonic'
+useful pond inch knock ritual matrix giggle attend dilemma convince coach amazing
+```
+
+
+
+### Using Mnemonics (with a password)
+
+
+All mnemonic phrases have a password, but the default is to use the empty
+string (i.e. `""`) as the password. If you have a password on your
+mnemonic, the `--mnemonic-password` will prompt for the password to
+use to decrypt the account.
+
+
+```
+/home/ricmoo> ethers --account public-mnemonic.txt --mnemonic-password
+Password (mnemonic): ******
+network: homestead (chainId: 1)
+homestead> accounts[0].getAddress()
+<Promise id=0 resolved>
+'0x6d3F723EC1B73141AA4aC248c3ab34A5a1DAD776'
+homestead>
+```
+
+
+
+### Using Mnemonics (with experimental memory-hard passwords)
+
+
+The `--xxx-mnemonic-password` is similar to the `--mnemonic-password` options,
+which uses a password to decrypt the account for a mnemonic, however it passes
+the password through the [scrypt](../../Users/ricmoo/Development/ethers/ethers.js-v5/https:/en.wikipedia.org/wiki/Scrypt)
+*password-based key derivation function* first, which is intentionally slow and makes
+a brute-force attack far more difficult.
+
+
+```
+/home/ricmoo> ethers --account mnemonic.txt --xxx-mnemonic-password
+Password (mnemonic; experimental - hard): ******
+Decrypting... 100%
+network: homestead (chainId: 1)
+homestead> accounts[0].getAddress()
+<Promise id=0 resolved>
+'0x56FC8792cC17971C19bEC4Ced978beEA44711EeD'
+homestead>
+```
+
+
+
+#### Note
+
+This is still an experimental feature (hence the `xxx`).

+<p>All mnemonic phrases have a password, but the default is to use the empty string (i.e. <code class="inline">""</code>) as the password. If you have a password on your mnemonic, the <code class="inline">--mnemonic-password</code> will prompt for the password to use to decrypt the account.</p>

+<p>The <code class="inline">--xxx-mnemonic-password</code> is similar to the <code class="inline">--mnemonic-password</code> options, which uses a password to decrypt the account for a mnemonic, however it passes the password through the <a href="https://en.wikipedia.org/wiki/Scrypt">scrypt</a> <i>password-based key derivation function</i> first, which is intentionally slow and makes a brute-force attack far more difficult.</p>

+
+Making Your Own
+===============
+
+
+The *cli* library is meant to make it easy to create command
+line utilities of your own.
+
+
+CLI
+---
+
+
+A **CLI** handles parsing all the command-line flags, options and arguments
+and instantiates a [Plugin](./) to process the command.
+
+A **CLI** may support multiple [Plugin](./)'s in which case the first
+argument is used to determine which to run (or if no arguments, the default
+plugin will be selected) or may be designed to be standalone, in which case
+exactly one [Plugin](./) will be used and no command argument is allowed.
+
+
+#### **addPlugin** ( command , pluginClass )  **=>** *void*
+
+Add a *plugin* class for the *command*. After all options and flags
+have been consumed, the first argument will be consumed and the
+associated plugin class will be instantiated and run.
+
+
+
+
+#### **setPlugin** ( pluginClass )  **=>** *void*
+
+Set a dedicated [Plugin](./) class which will handle all input. This
+may not be used in conjuction with addPlugin and will not automatically
+accept a command from the arguments.
+
+
+
+
+#### **showUsage** (  [ message="" [  , status=0 ]  ]  )  **=>** *never*
+
+Shows the usage help screen for the CLI and terminates.
+
+
+
+
+#### **run** ( args )  **=>** *Promise< void >*
+
+Usually the value of *args* passed in will be `process.argv.slice(2)`.
+
+
+
+
+Plugin
+------
+
+
+Each **Plugin** manages each command of a CLI and is executed in phases.
+
+If the usage (i.e. help) of a CLI is requested, the static methods `getHelp`
+and `getOptionHelp` are used to geneate the help screen.
+
+Otherwise, a plugin is instantiated and the `prepareOptions` is called. Each
+plugin **must** call `super.prepareOptions`, otherwise the basic options are
+not yet processed. During this time a Plugin should consume all the flags and
+options it understands, since any left over flags or options will cause the
+CLI to bail and issue an *unknown option* error. This should throw if a value
+for a given option is invalid or some combination of options and flags is not
+allowed.
+
+Once the prepareOptions is complete (the returned promise is resolved), the `prepareArguments`
+is called. This should validate the number of arguments is expected and throw
+and error if there are too many or too few arguments or if any arguments do not
+make sense.
+
+Once the prepareArguments is complete (the returned promise is resolved), the `run`
+is called.
+
+
+#### *plugin* . **network** **=>** *[Network](../../api/providers/types)*
+
+The network this plugin is running for.
+
+
+
+
+#### *plugin* . **provider** **=>** *[Provider](../../api/providers/provider)*
+
+The provider for this plugin is running for.
+
+
+
+
+#### *plugin* . **accounts** **=>** *Array< [Signer](../../api/signer) >*
+
+The accounts passed into the plugin using `--account`,
+`--account-rpc` and `--account-void` which this plugin can use.
+
+
+
+
+#### *plugin* . **gasLimit** **=>** *[BigNumber](../../api/utils/bignumber)*
+
+The gas limit this plugin should use. This is null if unspecified.
+
+
+
+
+#### *plugin* . **gasPrice** **=>** *[BigNumber](../../api/utils/bignumber)*
+
+The gas price this plugin should use. This is null if unspecified.
+
+
+
+
+#### *plugin* . **nonce** **=>** *number*
+
+The initial nonce for the account this plugin should use.
+
+
+
+
+### Methods
+
+
+
+#### *plugin* . **prepareOptions** ( argParser [  , verifyOnly=false ]  )  **=>** *Promise< void >*
+
+
+
+
+
+
+#### *plugin* . **prepareArgs** ( args )  **=>** *Promise< void >*
+
+
+
+
+
+
+#### *plugin* . **run** (  )  **=>** *Promise< void >*
+
+
+
+
+
+
+#### *plugin* . **getAddress** ( addressOrName [  , message="" ,  [ allowZero=false ]  ]  )  **=>** *Promise< string >*
+
+A plugin should use this method to resolve an address. If the resovled address is
+the zero address and *allowZero* is not true, an error is raised.
+
+
+
+
+#### *plugin* . **dump** ( header , info )  **=>** *void*
+
+Dumps the contents of *info* to the console with a *header* in a nicely
+formatted style. In the future, plugins may support a JSON output format
+which will automatically work with this method.
+
+
+
+
+#### *plugin* . **throwUsageError** (  [ message="" ]  )  **=>** *never*
+
+Stops exectuion of the plugin and shows the help screen of the plugin with
+the optional *message*.
+
+
+
+
+#### *plugin* . **throwError** ( message )  **=>** *never*
+
+Stops execution of the plugin and shows *message*.
+
+
+
+
+### Static Methods
+
+
+
+#### *Plugin* . **getHelp** **=>** *Help*
+
+Each subclass should implement this static method which is used to
+generate the help screen.
+
+
+
+
+#### *Plugin* . **getOptionHelp** **=>** *Array< Help >*
+
+Each subclass should implement this static method if it supports
+additional options which is used to generate the help screen.
+
+
+
+
+ArgParser
+---------
+
+
+The **ArgParser** is used to parse a command line into flags, options
+and arguments.
+
+
+```
+/home/ethers> ethers --account wallet.json --yes send ricmoo.eth 1.0
+#  An Option ----------^                     ^   ^
+#    - name =  "account"                     |   |
+#    - value = "wallet.json"                 |   |
+#  A Flag -----------------------------------+   |
+#    - name  = "yes"                             |
+#    - value = true                              |
+#  Arguments ------------------------------------+
+#    - count = 3
+#    - [ "send", "ricmoo.eth", "1.0" ]
+```
+
+
+Flags are simple binary options (such as the `--yes`), which are true if present
+otherwise false.
+
+Options require a single parameter follow them on the command line
+(such as `--account wallet.json`, which nhas the name `account` and the value
+`wallet.json`)
+
+Arguments are all other values on the command line, and are not accessed through
+the **ArgParser** directly.
+
+When a CLI is run, an **ArgParser** is used to validate the command line by using
+prepareOptions, which consumes all flags and options leaving only the arguments
+behind, which are then passed into prepareArgs.
+
+
+#### *argParser* . **consumeFlag** ( name )  **=>** *boolean*
+
+Remove the flag *name* and return true if it is present.
+
+
+
+
+#### *argParser* . **consumeMultiOptions** ( names )  **=>** *Array< {name:string,value:string} >*
+
+Remove all options which match any name in the Array of *names*
+with their values returning the list (in order) of values.
+
+
+
+
+#### *argParser* . **consumeOption** ( name )  **=>** *string*
+
+Remove the option with its value for *name* and return the value. This
+will throw a UsageError if the option is included multiple times.
+
+
+
+
+#### *argParser* . **consumeOptions** ( name )  **=>** *Array< string >*
+
+Remove all options with their values for *name* and return the list
+(in order) of values.

+<p>Each <b>Plugin</b> manages each command of a CLI and is executed in phases.</p><p>If the usage (i.e. help) of a CLI is requested, the static methods <code class="inline">getHelp</code> and <code class="inline">getOptionHelp</code> are used to geneate the help screen.</p><p>Otherwise, a plugin is instantiated and the <code class="inline">prepareOptions</code> is called. Each plugin <b>must</b> call <code class="inline">super.prepareOptions</code>, otherwise the basic options are not yet processed. During this time a Plugin should consume all the flags and options it understands, since any left over flags or options will cause the CLI to bail and issue an <i>unknown option</i> error. This should throw if a value for a given option is invalid or some combination of options and flags is not allowed.</p><p>Once the prepareOptions is complete (the returned promise is resolved), the <code class="inline">prepareArguments</code> is called. This should validate the number of arguments is expected and throw and error if there are too many or too few arguments or if any arguments do not make sense.</p><p>Once the prepareArguments is complete (the returned promise is resolved), the <code class="inline">run</code> is called.</p>

 <p>The ethers.js library is something that I've written out of necessity, and has grown somewhat organically over time.</p><p>Many things are the way they are for good (at the time, at least) reasons, but I always welcome criticism, and am completely willing to have my mind changed on things.</p><p>So, pull requests are always welcome, but please keep a few points in mind:</p><ul><li>Backwards-compatibility-breaking changes will not be accepted; they may be considered for the next major version</li><li>Security is important; adding dependencies require fairly convincing arguments as to why</li><li>The library aims to be lean, so keep an eye on the dist/ethers.min.js file size before and after your changes</li><li>Add test cases for both expected and unexpected input</li><li>Any new features need to be supported by me (future issues, documentation, testing, migration), so anything that is overly complicated or specific may not be accepted</li></ul><p>In general, <b>please start an issue <i>before</i> beginning a pull request</b>, so we can have a public discussion and figure out the best way to address to problem/feature. <b>:)</b></p>

+Migration: From Ethers v4
+=========================
+
+
+
+BigNumber
+---------
+
+
+
+### Namespace
+
+
+Since [BigNumber](../../api/utils/bignumber) is used quite frequently, it has been moved to
+the top level of the umbrella package.
+
+
+```
+// v4
+ethers.utils.BigNumber
+ethers.utils.BigNumberish
+
+// v5
+ethers.BigNumber
+ethers.BigNumberish
+```
+
+
+
+### Creating Instances
+
+
+The `bigNumberify` method was always preferred over the constructor
+since it could short-circuit an object instantiation for [[bignumber]
+objects (since they are immutable). This has been moved to a static
+`from` class method.
+
+
+```
+// v4
+new ethers.utils.BigNumber(someValue)
+ethers.utils.bigNumberify(someValue);
+
+// v5
+// - Constructor is private
+// - Removed `bigNumberify`
+ethers.BigNumber.from(someValue)
+```
+
+
+
+Contracts
+---------
+
+
+```
+TODO
+```
+
+
+
+Errors
+------
+
+
+
+### Namespace
+
+
+All errors now belong to the [Logger](../../api/utils/logger) class and the related functions
+have been moved to [Logger](../../api/utils/logger) instances, which can include a per-package
+version string.
+
+Global error fucntions have been moved [Logger](../../api/utils/logger) class methods.
+
+
+```
+// v4
+ethers.errors.UNKNOWN_ERROR
+ethers.errors.*
+
+errors.setCensorship(censorship, permanent)
+errors.setLogLevel(logLevel)
+
+errors.checkArgumentCount(count, expectedCount, suffix)
+errors.checkNew(self, kind)
+errors.checkNormalize()
+errors.throwError(message, code, params)
+errors.warn(...)
+errors.info(...)
+
+// v5
+ethers.utils.Logger.errors.UNKNOWN_ERROR
+ethers.utils.Logger.errors.*
+
+Logger.setCensorship(censorship, permanent)
+Logger.setLogLevel(logLevel)
+
+const logger = new ethers.utils.Logger(version);
+logger.checkArgumentCount(count, expectedCount, suffix)
+logger.checkNew(self, kind)
+logger.checkNormalize()
+logger.throwError(message, code, params)
+logger.warn(...)
+logger.info(...)
+```
+
+
+
+Interface
+---------
+
+
+The [Interface](../../api/utils/abi) object has undergone the most dramatic changes.
+
+It is no longer a meta-class and now has methods that simplify handling
+contract interface operations without the need for object inspection and
+special edge cases.
+
+
+### Functions
+
+
+```
+// v4 (example: "transfer(address to, uint amount)")
+interface.functions.transfer.encode(to, amount)
+interface.functions.transfer.decode(callData)
+
+// v5
+interface.encodeData("transfer", [ to, amount ])
+interface.decodeResult("transfer", data)
+
+// Or you can use any compatible signature or Fragment objects.
+// Notice that signature normalization is performed for you,
+// e.g. "uint" and "uint256" will be automatically converted
+interface.encodeData("transfer(address,uint)", [ to, amount ])
+interface.decodeResult("transfer(address to, uint256 amount)", data)
+```
+
+
+
+### Events
+
+
+```
+// v4 (example: Transfer(address indexed, address indexed, uint256)
+interface.events.Transfer.encodeTopics(values)
+interface.events.Transfer.decode(data, topics)
+
+// v5
+interface.encodeFilterTopics("Transfer", values)
+interface.encodeEventLog("Transfer", data, topics)
+```
+
+
+
+### Inspection
+
+
+Interrogating properties about a function or event can now (mostly) be
+done directly on the [Fragment](../../api/utils/abi) object.
+
+
+```
+// v4
+interface.functions.transfer.name
+interface.functions.transfer.inputs
+interface.functions.transfer.outputs
+interface.functions.transfer.payable
+interface.functions.transfer.gas
+
+// v5
+const functionFragment = interface.getFunction("transfer")
+functionFragment.name
+functionFragment.inputs
+functionFragment.outputs
+functionFragment.payable
+functionFragment.gas
+
+
+// v4; type is "call" or "transaction"
+interface.functions.transfer.type
+
+// v5; constant is true (i.e. "call") or false (i.e. "transaction")
+functionFragment.constant
+
+
+// v4
+interface.events.Transfer.anonymous
+interface.events.Transfer.inputs
+interface.events.Transfer.name
+
+// v5
+const eventFragment = interface.getEvent("Transfer");
+eventFragment.anonymous
+eventFragment.inputs
+eventFragment.name
+
+
+// v4
+const functionSig = interface.functions.transfer.signature
+const sighash = interface.functions.transfer.sighash
+
+const eventSig = interface.events.Transfer.signature
+const topic = interface.events.Transfer.topic
+
+// v5
+const functionSig = functionFragment.format()
+const sighash = interface.getSighash(functionFragment)
+
+const eventSig = eventFragment.format()
+const topic = interface.getTopic(eventFragment)
+```
+
+
+
+Utilities
+---------
+
+
+
+### Renaming
+
+
+```
+TODO
+```
+
+
+
+Wallet
+------
+
+
+
+### Mnemonic Phrases
+
+
+The **mnemonic** phrase and related properties have been merged into
+a single `mnemonic` object, which also now includes the `locale`.
+
+
+```
+// v4
+wallet.mnemonic
+wallet.path
+
+// v5
+// - Mnemonic phrase and path are a Mnemonic object
+// - Note: wallet.mnemonic is null if there is no mnemonic
+wallet.mnemonic.phrase
+wallet.mnemonic.path
+```

+ASM Utilities
+=============
+
+**Experimental** Do not use this package in production (yet)
+
+-----
+
+A semi-advanced EVM assembler.
+
+**Features**
+
+- Nested code scoping allows relative jumps
+- Execute JavaScript meta-programming inline
+- Self-padding data blocks
+- TODO: optional Position-Independant-Code
+- MIT licensed.
+
+Command-Line Interface
+======================
+
+@TODO: Add this to the CLI package.
+
+```
+/home/ethers> ethers-asm [ --disassemble ] [ FILENAME ]
+```
+
+Syntax
+======
+
+Comments
+--------
+
+Any text that occurs after a semi-colon (i.e. `;`) is treated as a comment.
+
+```
+; This is a comment. If a comments spans multiple
+; lines, it needs multiple semi-colons.
+
+@foobar:          ; Here is another comment
+```
+
+Opcodes
+-------
+
+Each OPCODE may be specified using either the **functional notations** or
+the **stack notation**.
+
+### Functional Notation
+
+This is the recommended syntax for opcodes as the assembler will perform
+the additional step of verifying the correct number of operands are passed
+in for the giver operation.
+
+```
+blockhash(sub(number, 1))
+```
+
+### Stack Notation
+
+This method is often useful when adapting other existing disassembled
+bytecode.
+
+```
+1
+number
+sub
+blockhash
+```
+
+Labels
+------
+
+Labels are used for control flow, by providing an achor that can be used
+by `JUMP` and `JUMPI`.
+
+A label is relative to its **scope** and cannot be references outside of
+its exact scope and automatically injects a `JUMPDEST` opcode.
+
+```
+@top:
+    jump($top)
+```
+
+Data Blocks
+-----------
+
+Sometimes verbatim data is desired, for example, embedding strings or
+look-up tables.
+
+This can be any number of **hexstrings**, **decimal bytes** or **evals**.
+
+A **data block** is automatically padded to ensure that any data that is
+coincidentally a PUSH opcode does not impact code or data outside the
+data block.
+
+A **data** exposes two variables: the offset (in the current scope) `$foo`
+and `#foo`, the length of the data. The offset may only be accessed from an
+ancestor scope while the length may be accessed from any scope.
+
+```
+codecopy(0x20, $foobar, #foobar)  ; Copy the data to memory address 32
+
+@foobar [
+    0x1234                        ; This is exactly 2 bytes (i.e. 4 nibbles)
+    42 65 73                      ; These are decmial values (3 bytes)
+]
+```
+
+Scopes
+------
+
+A scope is a new frame of reference, which offsets will be based on. This
+makes embedding code within code easier, since the jump destinations and
+**data blocks** can be accessed relatively.
+
+The top scope is named `_`.
+
+```
+
+// This runs the deployment
+sstore(0, ${{ toUtf8Bytes("Hello World") }})
+codecopy(0, $deployment, #deployment)
+return (0, #deployment)
+
+@contract {
+  @label:
+      jump($label)    
+}
+```
+
+Evaluation and Execution
+------------------------
+
+It is often useful to be able to modify a program in more advanced ways
+at code generation time. JavaScript code can be executed in a `{{! code }}``
+which does not place any output in the code, but can be used to define
+functions and variables and code can be evaluated in a ``{{= code }}``
+which will place the output of the *code* into the assembled output, following
+the same rules as **Data Blocks**.
+
+```
+{{!
+    function foo() { return 42; }
+}}
+
+{{= foo() }}
+1
+add
+```
+
+Notes
+=====
+
+Because of the nature of script evaluation, it is possible to create
+programs which cannot actually be assembled. The assembler will give
+up after 512 attempts to find a stable organization of the code.
+
+For example, this code contains a scope named `junk`, which is a `CALLER`
+statement followed by a data block equal to the bytecode of `junk`. Since
+this is recursive, there is never any way for this to be satisfied. This is
+similar to VHDL programs where it is possible to simulate recursion, but
+impossible to synthesize recursive hardware.
+
+```
+@junk {
+    caller
+    @thisIsRecursive[
+       {{= junk }}
+    ]
+}
+```
+
+Or code that tries to include its own hash internally:
+
+```
+@myContract {
+
+   ; NOT OK! hash(hash(hash( .... (data))) will never resolve stable bytecode
+   @checksumBad[
+       {{= keccak256(myContract) }}
+   ]
+
+   ; The hash excluding of bytecode excluding the checksum works.
+   @checksumOk[
+       {{= keccak256(myContract.slice(0, checksumOk.offset)) }}
+       {{= zeroPad("0x", 32) }}
+       {{= keccak256(myContract.slice(checksumOk.offset + 32)) }}
+   ]
+
+   ; But this is fine... The source code of a file does not change
+   @checksumGood[
+      {{= id(myContract.source) }
+   ]
+
+   ; Even better; this will make disassembled code look nicer...
+   @checksumBest[
+      {{= concat([ Opcode.from("PUSH32"), id(myContract.source) ]) }
+   ]
+}
+```
+
+Building
+========
+
+If you make changes to the `grammar.jison` file, make sure to run the `npm generate`
+command to re-build the AST parser.
