Hardhat is an open-source suite of tools designed to facilitate the development of smart contracts and decentralized applications (dApps) on the Ethereum blockchain. It provides a flexible and extensible local development environment, helping developers manage tasks such as running tests, debugging code, and deploying contracts to the live network. Originally created by Nomic Labs, the project and its team are now maintained by the Nomic Foundation, a non-profit organization dedicated to empowering developers to build a decentralized internet.
