CHECKER

To run this tool install Rust and Scarb

Build

scarb build

cargo build

Usage

First of all install starknet-devnet with specified version

cargo install starknet-devnet --version 0.0.7

Now run starknet-devnet

starknet-devnet --state-archive-capacity full --dump-on exit --dump-path dumpdir --seed 0

After building the crate, you can use it to check the compatibility between the supported versions of Starknet Devnet.

cargo run -p checker -- \
    --url http://127.0.0.1:5050/ \
    --l1-network-url <L1_NETWORK_URL> \
    --sierra-path target/dev/contracts_contracts_sample_contract_1_HelloStarknet.contract_class.json \
    --casm-path target/dev/contracts_contracts_sample_contract_1_HelloStarknet.compiled_contract_class.json \
    --sierra-path-2 target/dev/contracts_contracts_sample_contract_2_HelloStarknet.contract_class.json \
    --casm-path-2 target/dev/contracts_contracts_sample_contract_2_HelloStarknet.compiled_contract_class.json \
    --devnet-tests \
    --private-key <PRIVATE_KEY> \
    --account-address <ACCOUNT_ADDRESS> \
    --account-class-hash <ACCOUNT_CLASS_HASH> \
    --erc20-strk-contract-address <ERC20_STRK_CONTRACT_ADDRESS> \
    --erc20-eth-contract-address <ERC20_ETH_CONTRACT_ADDRESS> \
    --amount-per-test <AMOUNT_PER_TEST> \
    --version v7

Note on L1 Network URL: For the --l1-network-url parameter, you can use various Ethereum node providers:

• Alchemy: https://eth-sepolia.g.alchemy.com/v2/YOUR_API_KEY
• Infura: https://sepolia.infura.io/v3/YOUR_PROJECT_ID
• QuickNode: https://YOUR_SUBDOMAIN.quiknode.pro/YOUR_API_KEY/

t8n Tool

Overview

The t8n tool is designed to process transactions and manage state changes in the Starknet ecosystem. It reads input transactions from a JSON file, processes them, and outputs the resulting state to another JSON file. The tool is flexible and can be configured using environment variables to point to the necessary input and output files.

Usage

Initial State Mode

Use the initial state mode to start with a fresh state:

cargo run -p t8n -- --txns-path t8n/src/starknet/input/txns.json --state-path target/t8n/output.json --acc-path t8n/src/starknet/input/acc.json

Forwarded State Mode

You can use the forwarded state mode to initialize the state from a previous t8n run:

cargo run -p t8n -- --txns-path t8n/src/starknet/input/txns_2.json --state-path target/t8n/output.json --forwarded-state

For more details, see t8n readme

t9n Tool

Overview

The t9n tool is a command-line utility designed to ensure the integrity and correctness of transactions on the StarkNet network. This tool performs two critical functions:

1. Signature Verification: It verifies the cryptographic signature of the transaction to ensure that it has been signed by the correct private key corresponding to the provided public key.

2. Transaction Structure Validation: It checks the structure of the transaction JSON file to ensure it conforms to the expected format and includes all required fields.

Example run

Invoke_V1

cargo run -p t9n -- --file-path t9n/examples/invoke/invoke_txn_v1.json --public-key 0x39d9e6ce352ad4530a0ef5d5a18fd3303c3606a7fa6ac5b620020ad681cc33b --chain-id 0x534e5f5345504f4c4941

For more examples, see t9n readme

b11r Tool

Overview

The b11r tool is designed to create and validate Starknet blocks from the output of the t8n tool. It processes transaction receipts, events, and state changes according to the guidelines specified in the Starknet documentation, ensuring blocks are consistent with the Starknet protocol.

By default, the b11r tool can receive output directly from the t8n tool. Before running b11r, you first need to run the t8n tool to generate the required input. You can also specify a custom input file in JSON format, as described below.

Usage

Default Input from t8n

By default, the b11r tool expects input from the output of the t8n tool. Make sure you run t8n first to generate the state and transaction data. You can follow the instructions on how to run the t8n tool here:

t8n README - How to Run

Once the t8n tool has been run, you can execute b11r like this:

cargo run -p b11r
