A Hardhat Plugin For Replicable Deployments And Easy Testing
Note: This is the documentation for hardhat-deploy v2 that works with hardhat v3
Documentation for hardhat-deploy v1 can be found on the v1 branch
hardhat-deploy make it easy for you to deploy your EVM smart contracts across many chains.
The version 2 is a full rewrite that has been already used in production for several years. It does not support yet all the features of version 1 but is fully modular and it is thus much easier to contribute to new deployment mechanism.
Under the hood, hardhat-deploy uses rocketh a framework agnostic system that provide a minimal api to save and load deployment.
Everything else is handled by external module. For example @rocketh/deploy give you a deploy function that you can use to deploy contracts.
But you can provide your own module for advanced use case.
There are already a few like @rocketh/proxy to deploy proxy declaratively like in hardhat-deploy v1 or @rocketh/diamond to deploy diamond declaratively.
