Basic Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts.

Try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
node scripts/sample-script.js
npx hardhat help

---

npm init -y

npm install --save-dev hardhat

npx hardhat - Create a basic sample project

npm install --save-dev @nomiclabs/hardhat-ethers ethers

npx hardhat node - run local hardhat blockchain, do not close the console
