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. npm install

npm install --save dotenv

Try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test test/years.js
npx hardhat node
node scripts/sample-script.js
npx hardhat run scripts/deploy.js --network ropsten #部署合约到ropstem
npx hardhat run scripts/app.js --network rinkeby
npx hardhat run scripts/app.js --network mainnet
npx hardhat help

上传合约源码到etherscan

npx hardhat verify --network <DEPLOYED_CONTRACT_ADDRESS> "Constructor argument 1" verify的参数必须要和发布合约的参数保持一致，才能通过验证

npm install --save-dev @nomiclabs/hardhat-etherscan
npx hardhat verify --network mainnet 0x333D2Ed270B743A30d680E4f0EAddB6cA05db0DD "https://nftstorage.link/ipfs/bafybeiek32szlvffaehem5njtt6fzsnorjn2sqssrx5kzx6szfg7ee22ti/"
