Buidler Versions Save

This version adds support for using the Hardhat network helpers on the Anvil network (thanks @tmigone!)

This release adds experimental support for ESM in typescript projects.

In addition to that, the hardhat-shorthand tool (hh) now supports scoped tasks.

This release fixes a couple of issues:

• A problem in low-traffic chains that resulted in txs using a maxPriorityFeePerGas of 0, which were then rejected by the node.
• A bug in the compiler downloader that was triggered in big projects that used many different versions of solc.

Besides that, the project initialization now uses the latest version of the Hardhat Toolboxes.

@nomicfoundation/hardhat-web3-v4 is a new plugin that lets you use the latest version of the Web3.js library, developed as a collaboration between the Nomic Foundation and ChainSafe.

This release adds support for the polygonZkEVM and polygonZkEVMTestnet networks. It also fixes a minor issue related to a case-sensitive address comparison for detecting verified contracts.

This version of the viem-based Hardhat Toolbox bumps the version of hardhat-verify. This is a new major because the new version of that peer dependency is not compatible with the previous one, but you can consider this a low-risk upgrade.

This version of Hardhat Toolbox bumps the versions of hardhat-verify and typechain. This is a new major because the new versions of those peer dependencies are not compatible with the previous ones, but you can consider this a low-risk upgrade.

This release adds support for passing block tags as bigints.

This new version of Hardhat introduces a new feature: Configuration Variables!

Configuration variables let you use values in a configuration file without making them part of your project. They work as a replacement for environment variables and dotenv, but are more flexible and powerful. Read our guide to learn more.

This version also adds support for solc v0.8.22.

This release fixes a problem with the Vyper compiler downloader.
