Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.
Foundry consists of:
- Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
- Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
- Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
- Chisel: Fast, utilitarian, and verbose solidity REPL.
