Hardhat 3

Beta status

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.

Migration readiness

Section titled “Migration readiness”

We don’t expect any major user-facing breaking change in the API, so we encourage projects to migrate to Hardhat 3.

Take a look at the migration guide to see how to do it.

Work in progress features

Section titled “Work in progress features”

There are some features that are still in development, and should be released soon:

  • Ledger support: We are working on porting over the @nomicfoundation/hardhat-ledger plugin, and should be available soon.

  • Gas snapshots: The ability to take gas snapshots and compare them is still under development.

  • hardhat-deploy support: We are working on porting over the hardhat-deploy plugin to Hardhat 3.
