v2.21.0: Hardhat v2.21.0 — Introducing EDR

Compare Source

This version of Hardhat marks the debut of EDR (Ethereum Development Runtime), our new Rust-based runtime that is a complete rewrite of the original TypeScript-based Hardhat Network. This release lays a new long-term foundation for Hardhat's evolution over the coming year.

There are no functional changes, but there are some performance improvements across the board, which we’ll continue to expand in future updates.

Given the significance of this internal change, there’s a possibility of bugs. If you encounter any problems specific to this version, please report them by opening an issue. You should be able to downgrade to v2.20.1 without losing functionality if needed.

solidity-coverage out-of-memory issues

The solidity-coverage plugin works by heavily instrumenting the code, which sometimes causes OOM (out-of-memory) issues. This new version of Hardhat can, in certain cases, make those problems more likely.

If you run into this, you can fix it by using Node.js’s --max-old-space-size flag:

NODE_OPTIONS="--max-old-space-size=8192" npx hardhat coverage

Dropping support for Node.js v16

As part of this release, we are dropping support for Node.js v16. This version of Node.js reached its end-of-life in September of last year. You can learn more about our support guarantees here.

v2.20.1: Hardhat v2.20.1

Compare Source

This release fixes a bug when hardhat_setStorageAt was used in untouched addresses.

v2.20.0: Hardhat v2.20.0 — Cancun

Compare Source

This release adds support for the upcoming cancun hardfork. This hardfork is not enabled by default; if you want to use it, then you have to enable it in your Hardhat config:

module.exports = {
  networks: {
    hardhat: {
      hardfork: "cancun",
    },
  },
}

Keep in mind that blob transactions are not supported yet. If you need this, please upvote or comment on this issue.

In addition, this release adds support for solc 0.8.24.
