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-etherscan 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.

Installation

We recommend using npm 7 or later. If you do that, then you just need to install the plugin itself:

npm install --save-dev @nomicfoundation/hardhat-toolbox

If you are using an older version of npm, you'll also need to install all the packages used by the toolbox.

npm install --save-dev @nomicfoundation/hardhat-toolbox @nomicfoundation/hardhat-network-helpers @nomicfoundation/hardhat-chai-matchers @nomiclabs/hardhat-ethers @nomiclabs/hardhat-etherscan chai ethers hardhat-gas-reporter solidity-coverage @typechain/hardhat typechain @typechain/ethers-v5 @ethersproject/abi @ethersproject/providers

That's also the case if you are using yarn:

yarn add --dev @nomicfoundation/hardhat-toolbox @nomicfoundation/hardhat-network-helpers @nomicfoundation/hardhat-chai-matchers @nomiclabs/hardhat-ethers @nomiclabs/hardhat-etherscan chai ethers hardhat-gas-reporter solidity-coverage @typechain/hardhat typechain @typechain/ethers-v5 @ethersproject/abi @ethersproject/providers
