使用Infura部署ERC20交互合约时遇构造函数参数缺失错误求助

我正在使用Infura开发一款可查询钱包内Token总余额并实现Token转账的智能合约，合约编译成功但部署时报错，相关代码及问题如下：

Transactions.sol #

// SPDX-License-Identifier: Unlicense

import "hardhat/console.sol";
import "@openzeppelin/contracts/token/ERC20/IERC20.sol";

contract Transactions {
    uint256 transactionCount;
    event Transfer(address from, address receiver, uint amount, string message, uint256 timestamp, string keyword);

    mapping(address => uint256) public balances; // 用于追踪每个地址的余额

    IERC20 private token;

    constructor(address _tokenAddress) {
        token = IERC20(_tokenAddress);
    }

    struct TransferStruct {
        address sender;
        address receiver;
        uint amount;
        string message;
        uint256 timestamp;
        string keyword;
    }

    TransferStruct[] transactions;

    function addToBlockchain(address payable receiver, uint amount, string memory message, string memory keyword) public {
        transactionCount += 1;
        transactions.push(TransferStruct(msg.sender, receiver, amount, message, block.timestamp, keyword));

        // 更新发送方和接收方的余额
        balances[msg.sender] -= amount;
        balances[receiver] += amount;

        emit Transfer(msg.sender, receiver, amount, message, block.timestamp, keyword);
    }

    function getAllTransactions() public view returns (TransferStruct[] memory) {
        return transactions;
    }

    function getTransactionCount() public view returns (uint256) {
        return transactionCount;
    }
    
    function getBalance() public view returns (uint256) {
        return token.balanceOf(msg.sender);
    }

    function balanceOf(address account) public view returns (uint256) {
        return token.balanceOf(account);
    }

    function sendTokens(address to, uint256 amount) public {
        require(token.allowance(msg.sender, address(this)) >= amount, "合约未获得转账授权");
        require(token.transferFrom(msg.sender, to, amount), "Token转账失败");
    }
}

问题原因及解决方案 #

问题原因 #

Transactions合约的构造函数要求传入一个ERC20代币地址_tokenAddress，但部署脚本deploy.js中调用TransactionsFactory.deploy()时没有传递该参数，导致参数缺失报错。

解决方案 #

修改deploy.js，在deploy()方法中传入目标ERC20代币的地址（以下用Sepolia测试网USDC地址举例，你可以替换为自己需要交互的代币地址）：

const { ethers } = require('hardhat');

// 替换为你要交互的ERC20代币地址，示例为Sepolia测试网USDC
const TOKEN_ADDRESS = "0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238";

const main = async () => {
  const TransactionsFactory = await hre.ethers.getContractFactory("Transactions");
  // 传入构造函数所需的代币地址参数
  const transactionsContract = await TransactionsFactory.deploy(TOKEN_ADDRESS);

  await transactionsContract.deployed();

  console.log("Transactions合约地址: ", transactionsContract.address);
};

const runMain = async () => {
  try {
    await main();
    process.exit(0);
  } catch (error) {
    console.error(error);
    process.exit(1);
  }
};

runMain();

额外注意事项：

• 确保使用的代币地址在目标网络（如Sepolia）上是有效的ERC20合约地址
• 部署账户需要持有足够的测试网ETH，用于支付合约部署的Gas费
