获取区块链代币历史转账事件的例子代码

以下是获取区块链代币历史转账事件的例子代码：

const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/your-project-id');

const contractAddress = 'x...'; // 代币合约地址
const fromBlock = ; // 起始块号
const toBlock = 'latest'; // 结束块号，设为 'latest' 表示最新块

// 获取 Transfer 事件
const transferEvent = new web3.eth.Contract([
  {
    "anonymous": false,
    "inputs": [
      {
        "indexed": true,
        "name": "from",
        "type": "address"
      },
      {
        "indexed": true,
        "name": "to",
        "type": "address"
      },
      {
        "indexed": false,
        "name": "value",
        "type": "uint256"
      }
    ],
    "name": "Transfer",
    "type": "event"
  }
], contractAddress);

// 获取历史事件
transferEvent.getPastEvents('Transfer', {
  fromBlock,
  toBlock
}, (error, events) => {
  console.log(events);
});

希望能对你有所帮助。
