Hardhat Setup

Project scaffolding.

What Is Hardhat

Hardhat is a development environment for Ethereum that helps you compile, test, deploy, and debug smart contracts.

  • Written in JavaScript/TypeScript and run with Node.js.
  • Ships with a built-in local Ethereum network.
  • Has a rich plugin ecosystem (ethers, waffle, gas reporter).

It is the most popular alternative to Truffle and Foundry for JS-centric teams.

Prerequisites

Before installing Hardhat you need Node.js (LTS recommended) and a package manager such as npm or yarn.

Check your versions to make sure the toolchain is ready:

node -v npm -v

Hardhat targets Node.js LTS releases, so avoid odd-numbered experimental versions.

node -v
npm -v
