Hardhat 3 is a major overhaul with exciting new features:

  • Solidity tests as a first-class testing option
  • Multichain support for today's rollup-centric world
  • Rust-powered runtime for faster execution
  • Revamped build system with full npm compatibility and build profiles
  • Hardhat Ignition for streamlined contract deployments

Hardhat 3 is production-ready and you can migrate today! We'll keep it in beta status as we work on missing features and stabilize it in the near future.

To install Hardhat 3, run the following commands in an empty directory:

npm init -y
