Foundry

Foundry is a fast, portable, and modular toolkit for Ethereum application development written in Rust. It includes Forge (a testing framework), Cast (a command-line tool for interacting with the blockchain), and Anvil (a local Ethereum node). It enables developers to write, test, deploy, and interact with smart contracts efficiently.

Also known as: Foundry Toolkit, Forge, Cast, Anvil, Foundry-rs

Why learn Foundry?

Developers should learn Foundry for Ethereum smart contract development due to its speed, built-in fuzzing capabilities, and seamless integration with Solidity. It is particularly useful for writing comprehensive tests, deploying contracts, and performing on-chain interactions in a developer-friendly environment, making it ideal for building decentralized applications (dApps) and auditing contracts.
