获取链信息 const Web3 = require('web3')
async function getChainId() {
const web3 = new Web3('https://http-mainnet.hecochain.com')let chainId = await web3.eth.getChainId()console.log(`chain id: ${chainId}`)return chainId
复制代码
}
生成账户 const Web3Accounts = require('web3-eth-accounts')
let account = new Web3Accounts().create()//do not do this on prd envconsole.log(account generated. address: ${account.address}, private key: ${account.privateKey})
建立交易 const Web3 = require('web3')
async function transfer(fromAccount, to, value){
const web3 = new Web3('https://http-mainnet.hecochain.com')let chainId = await web3.eth.getChainId()let nonce = await web3.eth.getTransactionCount(fromAccount.address)let gasPrice = await web3.eth.getGasPrice()
let unsigned = { from: fromAccount.address, to, value: web3.utils.numberToHex(web3.utils.toWei(value, 'ether')), gasPrice, nonce, chainId,}
unsigned.gas = await web3.eth.estimateGas(unsigned)
let signed = await fromAccount.signTransaction(unsigned)return signed
