Welcome to the world of Solidity smart contracts! In this article, we are going to explore a Hardhat-based template that simplifies your smart contract development with numerous sensible features. This guide will walk you through the setup process, usage, and even troubleshooting tips, making your journey smoother than ever.

What is Hardhat?

Hardhat is a powerful Ethereum development environment that simplifies the process of compiling, running, and testing smart contracts. With additional tools like TypeChain, Ethers, and Solhint, this template enhances your development experience with accurate code linting and TypeScript bindings.

Features of the Hardhat Template

• Hardhat: Compile, run, and test your smart contracts.
• TypeChain: Automatically generates TypeScript bindings for smart contracts.
• Ethers: An excellent library that makes interacting with Ethereum easier.
• Solhint: A code linter to help ensure your Solidity code is top-notch.
• Solcover: Provides code coverage reports to check how well your tests cover your contracts.
• Prettier Plugin Solidity: A code formatter that helps keep your code neat and tidy.

How to Set Up the Hardhat Template

Follow these steps to get your Hardhat template up and running:

Step 1: Use the Template

Click the Use this template button at the top of the Hardhat template repository to create your own copy.

Step 2: Install Dependencies

Once you have your repository, head over to your terminal and run:

sh
bun install

Step 3: Configure Hardhat

Set up the required Hardhat Configuration Variables using:

sh
bunx hardhat vars setup

For specific variables like the BIP-39 mnemonic, execute:

sh
bunx hardhat vars set MNEMONIC? Enter value: ‣ Put your twelve words mnemonic here

If you don’t have a mnemonic, you can generate one using this website.

Step 4: Compile Smart Contracts

To compile your smart contracts, use:

sh
bun run compile

Step 5: Run Tests

Once your contracts are compiled, run tests by executing:

sh
bun run test

Troubleshooting Tips

If you encounter issues during setup or usage, here are some troubleshooting ideas:

• Failed Linting: Ensure that your code adheres to Solidity best practices and check for common syntax errors.
• Failed to Compile: Verify that all required dependencies are installed and up to date. Run the installation command again to be sure.
• Test Failures: Review your contracts and tests for any logical errors or mismatches in expectations.
