Hardhat Toolbox

The @nomicfoundation/hardhat-toolbox plugin bundles all the commonly used packages and Hardhat plugins we recommend to start developing with Hardhat.

When you use this plugin, you'll be able to:

• Deploy and interact with your contracts using ethers.js and the hardhat-ethers plugin.
• Test your contracts with Mocha, Chai and our own Hardhat Chai Matchers plugin.
• Interact with Hardhat Network with our Hardhat Network Helpers.
• Verify the source code of your contracts with the hardhat-verify plugin.
• Get metrics on the gas used by your contracts with the hardhat-gas-reporter plugin.
• Measure your tests coverage with solidity-coverage.
• And, if you are using TypeScript, get type bindings for your contracts with Typechain.

Usage

To create a new project that uses the Toolbox, check our Setting up a project guide.

If you want to migrate an existing Hardhat project to use the Toolbox, read our migration guide.

Network Helpers

When the Toolbox is installed using npm 7 or later, its peer dependencies are automatically installed. However, these dependencies won't be listed in the package.json. As a result, directly importing the Network Helpers can be problematic for certain tools or IDEs. To address this issue, the Toolbox re-exports the Hardhat Network Helpers. You can use them like this:

import helpers from "@nomicfoundation/hardhat-toolbox/network-helpers";
