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 with balances.
Recommended to use Node.js v18+ and npm v8+
Try running some of the following tasks:
npm install
# Set/Read/Remove hardhat config variables
# npx hardhat vars set API_KEY
# npx hardhat vars get API_KEY
# npx hardhat vars DELETE API_KEY
# npx hardhat vars list
# set PRIVATE_KEY and ETHERSCAN API_KEY
npx hardhat vars set PRIVATE_KEY
npx hardhat vars set ETHERSCAN_API_KEY'
# starts local node
npx hardhat node
# compile contracts
npx hardhat compile
# deploy contract defined in tasks on specified network
npx hardhat deploy --network local
# deploy upgradeable contract in scripts/deploy-contract.ts on specified network
npx hardhat run scripts/deploy-contract.ts --network mumbai
# verify contract
npx hardhat verify --network <deployed network> <deployed contract address> "<constructor1>" "<constructor2>"
# upgrade contract in scripts/upgrade-contract.ts on specified network
# Lock.sol --> LockUpdated.sol
npx hardhat run scripts/upgrade-contract.ts --network mumbai
# check coverage using solidity-coverage plugin: supports hardhat network only
npx hardhat coverage --network hardhat
# unit tests including gas usage
npx hardhat test
# remove all compiled and deployed artifacts
npx hardhat clean
# show help
npx hardhat help
