Hardhat Boilerplate Deluxe

This repository contains a sample project that you can use as the starting point for your Ethereum project.

It's also a great fit for learning the basics of Smart Contracts for development of fat protocols, and thin applications that use shared data on a distributed ledger.

This project is intended to be used with the Decentralized Exchange Code Development video series, but you should be able to follow it by yourself by reading the README and exploring its contracts, tests, scripts and frontend directories.

Quick start

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

git clone https://github.com/hackingbeauty/hardhat-boilerplate-deluxe
cd hardhat-boilerplate-deluxe
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 run scripts/deploy.js --network localhost

Finally, we can run the frontend with:

cd frontend
npm install
npm start

Open http://localhost:3000/ to see your decentralized application. You will need to have Metamask installed and listening to localhost 8545.

User Guide

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

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

What's Included?

This repository uses our recommended hardhat setup, by using our @nomicfoundation/hardhat-toolbox. When you use this plugin, you'll be able to:

This project also includes a sample frontend/Dapp, which uses Create React App.

Troubleshooting

  • 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 > Reset Account.

Setting up your editor

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!

Develop A Decentralized Exchange

If you're new to developing DeFi protocols and decentralized applications on Ethereum, consider developing a decentralized exchange powered by Automated Market Maker technology. It's a great way to bootstrap your knowledge of how these software systems work.

To learn how to do this, check out the Decentralized Exchange Code Development 5-part series at "Web3 Blockchain Developer" and get step-by-step guidance.

There are two run-time targets you have to learn how to develop for if you want to implement decentralized business models on Ethereum. The first run-time target is the EVM (Ethereum Virtual Machine) which is the general purpose computer that processes Smart Contracts.

The second run-time target is the Web which allows you to connect a UI/UX to your DeFi protocols or decentralized applications.
