Foundry is a Blockchain development framework by Paradigm, and written in Rust.
It is composed by Cast, a CLI tool for interacting with smart contracts, and the testing framework Forge, which lets you write your tests in Solidity. Forge also allows to override the EVM state at test runtime and to fuzz your tests.
