This is the boilerplate for Hardhat Solidity Smart Contract & Typescript(TS) Projects for developers.

This project is intended to be used with the Hardhat Beginners Tutorial, but you should be able to follow it by yourself by reading the README and exploring its contracts, test, and ignition directories.

The first things you need to do are cloning this repository and installing its dependencies:

git clone https://github.com/0xapp123/Hardhat-Boilerplate.git
cd Hardhat-Boilerplate
npm install

Once installed, let's run Hardhat's testing network:

npx hardhat node

Then, on a new terminal, go to the repository's root folder and run this to deploy your contract:

npx hardhat ignition deploy ./ignition/modules/Lock.js --network localhost

You can find detailed instructions on using this repository and many tips in its documentation.

• Writing and compiling contracts
• Setting up the environment
• Testing Contracts
• Hardhat's full documentation

For a complete introduction to Hardhat, refer to this guide.

This repository uses our recommended hardhat setup, by using our @nomicfoundation/hardhat-toolbox. 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.

• Invalid nonce errors: if you are seeing this error on the npx hardhat node console, try resetting your Metamask account. This will reset the account's transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Clear activity tab data.

Hardhat for Visual Studio Code is the official Hardhat extension that adds advanced support for Solidity to VSCode. If you use Visual Studio Code, give it a try!
