1. 회원가입 후 로그인

2. create new project 버튼 클릭

3. product 는 이더리움으로 선택하고 이름을 기입

3. endpoint를 ropsten으로 선택

4. truffle-config.js 파일 수정

- 상단에 아래 코드 추가

- infuraKey 값을 위의 주소에서 v3/ 뒤의 값으로 변경

const HDWalletProvider = require('truffle-hdwallet-provider');
const infuraKey = "19fee616dd234a588542c166dc4f3f07";
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();

- networks 설정 부분에 아래 코드 추가

    ropsten: {
      provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/${infuraKey}`),
      network_id: 3,       // Ropsten's id
      gas: 5500000,        // Ropsten has a lower block limit than mainnet
      confirmations: 2,    // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 200,  // # of blocks before a deployment times out  (minimum/default: 50)
      skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )
    },
