Follow the tutorial on creating a smart contract in my GitHub to set up a backend. Initial Setup Add a HelloWorld.sol in contracts. Change the output directory for contracts Add the line: contracts_build_directory: "./client/src/contracts", in truffle_config.js Open the console $ truffle console --network goerli (or wherever the contract is to be deployed)
