chain2foundry

Generates a Foundry project from a contract address

Python 3

License: MIT

Install

sudo git clone https://github.com/erc1337-Coffee/chain2foundry
cd chain2foundry/
sudo apt install python3
sudo python3 -m pip install -r requirements.txt

Usage

$ python3 chain2foundry.py

usage: chain2foundry.py [-h] -a ADDRESS [-n NETWORK] [-k API-KEY] [-o OUTPUT_DIR] [-f]

optional arguments:
  -h, --help            				Show this help message and exit

  -a ADDRESS, --address ADDRESS         Contract address

  -n NETWORK, --network NETWORK         Network the contract is deployed on (default:mainnet / goerli)

  -k API-KEY, --api-key API-KEY         Etherscan API key (default: a shared one)

  -o OUTPUT_DIR, --output OUTPUT_DIR    Output directory

  -f, --force                           Overwrite the output directory if it already exists

Example

$ python3 chain2foundry.py -a 0x8A98E5c8211D20C6c1c82c78c46f5A0528062881 -n goerli -o /tmp/ -f

Fetching the contract source code from Etherscan API...
Creating project ApeCoinStaking at /tmp/ApeCoinStaking
Done ! gl hf fren :)

Todo

  • Test it to find bugs and edge cases
  • Proxies ?
  • Support all chains (if there's an API to fetch contract sources aka Polygon, AVAX, Arbitrum, Optimism...)
  • Automate tests creation
  • Automate constructor arguments parsing
  • How cool would it be if the script deployed contracts & populated them on an Anvil node with the same data as currently on-chain ?
