👷‍♂️ Create Hardhat DApp

The fastest way to initialize a new Hardhat development environment.

Features ⚡️

• Zero Configuration — No need to install and configure hardhat plugins manually
• Typescript by Default — Provides static typing for both JavaScript and Smart Contract ABI
• Extensible — Still a Hardhat environment that can be extended with many awesome plugins

Getting Started 📚

Start by running the command below and replace defi-app with the name of your project.

npx create-hardhat-dapp defi-app

Or using yarn

yarn create hardhat-dapp defi-app

Options 🪛

create-hardhat-dapp comes with the following option:

• -p, --provider [{ alchemy | infura }] — Prepare network configurations for connecting to networks using your favorite JSON-RPC provider. Leave it blank for alchemy

• --no-install — Prevent installing dependencies at beginning

• ethers.js — JavaScript library to interact with Ethereum
• hardhat-ethers — Extended version of ethers.js for Hardhat

Test

• waffle — Simple smart contract testing library
• mocha — Feature-rich JavaScript test framework
• chai — Assertion library paired with Mocha
