Bumps hardhat from 2.9.3 to 2.11.1.

Release notes

Sourced from hardhat's releases.

Hardhat v2.11.1

This release fixes a couple of bugs in v2.11.0:

  • Some chains, like Polygon, were causing issues when they were forked
  • The WASM version of the solidity compiler, which is used in some machines, was not being correctly downloaded.

Hardhat v2.11.0 — The Merge support and fast compilation

We are excited to release this new version of Hardhat, as it makes Hardhat Network compatible with The Merge and makes our compilation much faster. Read on to learn more about these and other improvements.

Support for The Merge

Hardhat Network now has support for The Merge. To try it out, use the new merge hardfork setting. This hardfork is not selected by default, but you can enable it in your config:

module.exports = {
  networks: {
    hardhat: {
      hardfork: "merge"
    }
  }  
};

Selecting this new hardfork will introduce a few changes to how Hardhat Network runs, but your contracts should still work without any modification. The rest of this section explains what these changes are.

The DIFFICULTY opcode (now renamed to PREVRANDAO) will return a pseudo-random value. This value is also exposed in the block header as mixHash.

You can use the new hardhat_setPrevRandao RPC method to modify the value returned by DIFFICULTY/PREVRANDAO in the next block. We recommend using the setPrevRandao network helper for this.

Hardhat Network’s JSON-RPC now accepts the new safe and finalized block tags, which in Hardhat Network are just aliases for the latest block tag, and correspond to the latest block.

Faster compilation

We optimized Hardhat’s compilation pipeline, significantly reducing the overhead it adds on top of solc. Compilation takes 40% less in most workflows, with a few taking 90% less!

How much of an impact this has depends on the size of your project, setup, and workflow, so we’ll explore two examples here, running the same benchmarks on each.

We’ll focus on a few different workflows:

  • Clean compilation: compiling the entire codebase from scratch
  • No recompilation: trying to compile when there has been no modification, and everything is cached.
  • Leaf contract: modifying and recompiling a contract with tons of dependencies but that’s not imported by others after a clean compilation.
  • Deep contract: modifying and recompiling a contract used in the entire codebase after a clean compilation
  • Syntax error: introducing a syntax error to the leaf contract and trying to recompile it after a clean compilation

Open Zeppelin Contracts

This project is an example of a large codebase with a JavaScript setup. We expect most JavaScript projects to see similar or better results.
