获取erc20地址所持有的所有币种

admin

要获取一个以太坊地址持有的所有ERC20代币，有几种方法可以实现：

方法一：使用区块链浏览器

• Etherscan (https://etherscan.io/)
  
  
  • 输入地址后，点击"Token"标签页
  • 可以查看该地址持有的所有ERC20代币及其余额
    
    
• Ethplorer (https://ethplorer.io/)
  • 专门用于查看地址的Token持有情况
  • 提供更详细的代币信息
    
    
  
  

方法二：使用API

• Etherscan API
  javascript
  
  
  
  // 获取地址的ERC20代币余额const apiKey = 'YOUR_API_KEY';const address = '0x...';const url = `https://api.etherscan.io/api?mod ... okentx&address=${address}&startblock=0&endblock=99999999&sort=asc&apikey=${apiKey}`;fetch(url)  .then(response => response.json())  .then(data => console.log(data.result));
  
• Alchemy/Infura API
  javascript
  
  
  
  const { Alchemy, Network } = require("alchemy-sdk");const config = {  apiKey: "YOUR_API_KEY",  network: Network.ETH_MAINNET,};const alchemy = new Alchemy(config);async function getTokenBalances(address) {  const balances = await alchemy.core.getTokenBalances(address);  console.log(balances);}
  
  

方法三：使用Web3库查询javascript



const Web3 = require('web3');const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_PROJECT_ID');// ERC20标准ABI（简化版）const erc20Abi = [  {    "constant": true,    "inputs": [{"name": "_owner", "type": "address"},    "name": "balanceOf",    "outputs": [{"name": "balance", "type": "uint256"},    "type": "function"  };async function getTokenBalance(tokenContract, userAddress) {  const contract = new web3.eth.Contract(erc20Abi, tokenContract);  const balance = await contract.methods.balanceOf(userAddress).call();  return balance;}// 示例：查询USDT余额const usdtAddress = '0xdac17f958d2ee523a2206206994597c13d831ec7';const userAddress = '0x...';getTokenBalance(usdtAddress, userAddress).then(console.log);
