Hardhat — 無法在 Rinkeby 上驗證 ERC20 代幣

我正在使用 Openzeppelin 的 ERC20 合約創建一個 ERC20 代幣，我使用它編寫了部署腳本hardhat-deploy並且它正在執行。但是，當嘗試在該智能合約的地址上執行安全帽驗證腳本時，我收到以下錯誤：

NomicLabsHardhatPluginError: More than one contract was found to match the deployed bytecode.
Please use the contract parameter with one of the following contracts:
 * @openzeppelin/contracts/token/ERC20/ERC20.sol:ERC20
 * contracts/TopGToken.sol:TopGToken

For example:

 hardhat verify --contract contracts/Example.sol:ExampleContract <other args>

If you are running the verify subtask from within Hardhat instead:

 await run("verify:verify", {
   <other args>,
   contract: "contracts/Example.sol:ExampleContract"
 };

這是我的智能合約：

// SPDX-Licence-Identifier: MIT

pragma solidity ^0.8.16;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract TopGToken is ERC20 {

 constructor(uint256 initialSupply, string memory name, string memory symbol) ERC20 (name, symbol) {
   _mint(msg.sender, initialSupply);
 }
}

這是我的部署文件：

const { network } = require('hardhat');
const { networkConfig, devChains } = require('../network.config');
const { verify } = require('../utils/verify');

module.exports = async ({ getNamedAccounts, deployments }) => {
 const { deploy, log } = deployments;
 const { deployer } = await getNamedAccounts();

 const currentNetwork = networkConfig[network.config.chainId];
 const isLocal = devChains.includes(currentNetwork.name);
 
 const initialSupply = currentNetwork.initialSupply;
 const name = "Top G Token";
 const symbol = "TOPG";

 const args = [
   initialSupply,
   name,
   symbol,
 ];

 const TopGToken = await deploy('TopGToken', {
   from: deployer,
   args,
   log: true,
   waitConfirmations: currentNetwork.blockConfirmations,
 });

 if(!isLocal){
   await verify(TopGToken.address, args);
 }

 log('-------------------------------------------------')
}

module.exports.tags = ['all', 'topgtoken'];

驗證文件：

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

async function verify(contractAddress, args) {
 try {
   await run("verify:verify", {
   address: contractAddress,
   constructorArguments: args,
   });
 } catch (error) {
   console.error(error)
 }
}

module.exports = {
 verify
};

Hardhat 在項目中發現了多個合約（您的 TopGTOken 和導入的 ERC20），它不知道您要驗證哪個字節碼。

您需要指定您的契約。

async function verify(contractAddress, args) {
 try {
   await run("verify:verify", {
   address: contractAddress,
   constructorArguments: args,
   contract: "contracts/TopGToken.sol"
   });
 } catch (error) {
   console.error(error)
 }
}
