How to generate new smart contracts?

Install the Hardhat (Solidity development environment)

npm install --save-dev hardhat@latest

npx hardhat

npx hardhat compile

npx hardhat test

If there is no any error after above steps, the environment works.

Run Solidity locally

npx hardhat run scripts/run.js

Deploy to remote public chain (goerli)

npx hardhat run scripts/deploy.js --network goerli

The result will give the new address of the smart contracts. Then the address needs to be modified in the web3.js.
