【英文标题】：Returned error: transaction underpriced in BEP-20 Token transaction

【发布时间】：2021-09-23 22:32:08

【问题描述】：

我尝试使用 web3.js 转移我的 BEP-20 令牌

我部署了新的 BEP-20 令牌，并且可以使用 MetaMask 将令牌发送到另一个地址。

我尝试在 nodejs 中传输。我按照指南发送令牌。

下面是我的代码

const sendBEP20Transaction =  async () => 

  var Web3 = require('web3');
  var web3 = new Web3(new Web3.providers.HttpProvider('https://bsc-dataseed1.binance.org'))

  var myAddress = '0xF3b6A45AFbC5892a70EA7ca5b10d61A500BeCeC1';
  var toAddress = '0xa5915F48DDD3A7D25Daf1AeBd5Df677389b679bA';
  var privateKey = 'd5...';  
  var abiArray = [...];
  var contractAddress = '0xcB39dAF817EC0BaDDF78719dA24768b3fe81A7b5';
  var amount = web3.utils.toHex(10)

 
  var count;

  await web3.eth.getTransactionCount(myAddress).then(function (v)  
    console.log('count: ', v); 
    count = v 
  )

  let account = web3.eth.accounts.wallet.add(privateKey);
  var contract = new web3.eth.Contract(abiArray, contractAddress, 
    from: myAddress,
    gasPrice: web3.utils.toHex(5),
    gasLimit: web3.utils.toHex(80000),
  )

  contract.methods.transfer(toAddress, amount).send( 
    from: '0xF3b6A45AFbC5892a70EA7ca5b10d61A500BeCeC1',
    gasPrice: web3.utils.toHex(5),
    gasLimit: web3.utils.toHex(80000),
  )
  .then()
  .catch(console.error);

当我运行此代码时，我收到错误“返回错误：交易价格过低”

请大家帮帮我，谢谢

【参考方案1】：

当您尝试替换交易并且替换的gas价格太低时，会发生“交易低估”错误。
