API List

API Reference

generate

It generates wallet in the network where MHC client runs.

Parameters

none

Returns

address - wallet

pub_key - wallet public key

prv_key - wallet private key

Besides, 2 files are created in the folder: /opt/mhp/wallet.main/ (main means that the network runs in the main network. There are several types of networks: main|dev|v8) with the name of a created wallet and prv and pub extensions for private and public keys, respectively.

Example

// Request
curl -s -X POST --data '{"id":1, "version":"1.0.0", "method":"generate"}' 0.0.0.0:9999

// Result
{
  "jsonrpc":"2.0",
  "id":1,
  "result": 
  {
    "address":"0x002382e6e78e4f97ee636ba6ff42e80a34c076c118cb288e3c",
    "pub_key":"30563...d0af",
    "prv_key":"307402...ed0af"
  }
}

// And files:
/opt/mhp/wallet.main/0x002382e6e78e4f97ee636ba6ff42e80a34c076c118cb288e3c.raw.prv

A message, which displays the result of calling the method. Examples:

  • valid address
  • address not valid
  • validation error

Example

// Request

Parameters

address - wallet address in HEX format.

Returns

address - wallet

countDelegatedOps - number of delegations

delegate - amount delegated from this address

undelegate - amount undelegated from this address (returned to this address)

forged - Total amount forged

If there are no delegation transactions in the address, such fields as countDelegatedOps, delegate, undelegate, delegated, undelegated won't be available.
