Install truffle

npm install -g truffle

initialize project

truffle init

Once this operation is completed, you'll now have a project structure with the following items:

contracts/: Directory for Solidity contracts

migrations/: Directory for scriptable deployment files

test/: Directory for test files for testing your application and contracts

truffle-config.js: Truffle configuration file

Compile contract

truffle compile

Truffle config file

const HDWalletProvider = require('@truffle/hdwallet-provider');
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();

module.exports = {
  networks: {
    development: {

  // Set default mocha options here, use special reporters etc.
  mocha: {
    // timeout: 100000
  },

  // Configure your compilers
  compilers: {
    solc: {
      version: "^0.6.12", // A version or constraint - Ex. "^0.5.0"
    }
  }
}

development network is on ganache. you can test smart contracts on ganache directly otherwise on testnet.

deploy smart contract

$ truffle migrate --network testnet
