JS生成以太坊地址\助记词\公私钥 Ethereum Adress/Private/Public Key

• mkdir walletDemo && cd walletDemo //创建一个项目目录，cd

• npm init //初始化npm项目

• yarn add bip39 ethereum-hdwallet //安装依赖

• node //执行

  const bip39 = require('bip39') //导入bip39模块
  const mnemonic = bip39.generateMnemonic()//生成随机助记词
  console.log(mnemonic)
  console.log(bip39.generateMnemonic())

  //js获取公私钥、地址
  //运行：node ethAddress.js
  
  //引入依赖
  const bip39 = require('bip39')
  const HDWallet = require('ethereum-hdwallet')
  
  //生成助记词
  const mnemonic = bip39.generateMnemonic(128,null,bip39.wordlists.chiness_simplified)console.log('助记词' + mnemonic);
  
  //通过随机助记词生成公私钥、地址
  async function getAdress(mnemonic) {    
      const seed = await bip39.mnemonicToSeed(mnemonic)//根据助记词生成seed    
      const hdwallet = HDWallet.fromSeed(seed)//通过seed获取hdWallet    
      const key = hdwallet.derive("m/44' /60' /0/0")//源于，得自。设置地址路径    
      console.log("PrivateKey = " + key.getPrivateKey().toString('hex'))//私钥    
      console.log("PublicKey = " + key.getPublicKey().toString('hex'))//公钥    
      const EthAddress = '0x' + key.getAddress().toString('hex')//地址    
      console.log("Eth Address = " + EthAddress)}//通过同一个seed获取多个地址
      async function getAdressFromSameSeed(mnemonic) {    
      const seed = await bip39.mnemonicToSeed(mnemonic)//根据助记词生成seed    
      const hdwallet = HDWallet.fromSeed(seed)//通过seed获取hdWallet  
    
      for(var i = 0; i < 10; i++) {
