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

Commands history

Init node project

Run npm init and just press p all the way until the package.json file is created

Installing hardhat

npm install --save-dev hardhat

Creating a sample project

Run npx hardhat and select Create a sample project

Installing dependencies:

npm install --save-dev @nomiclabs/hardhat-waffle ethereum-waffle chai @nomiclabs/hardhat-ethers ethers

Verifyint contracts

• Command line npx hardhat verify --network rinkeby 0xB51B1ABF43236cB53D434374E98e89f94Daa249a

• Programatically await hre.run("verify:verify", { address: hackFlip.address });

Running a deployment/hack script

Run npx hardhat run scripts/4_Telephone.js

Running a test script

Run npx hardhat test test/4_TelephoneTest.js --network hardhat. You can try in Rinkeby but you might run into timeouts due to slow block processing.
