Hardhat 2 验证
hardhat-monad 模板已预配置为同时在 MonadVision（Sourcify）和 Monadscan（Etherscan）上验证合约。如果您使用该模板，您的 hardhat.config.ts 应该已经包含：import type { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox-viem";
import "@nomicfoundation/hardhat-ignition-viem";
import "dotenv/config";
const PRIVATE_KEY = process.env.PRIVATE_KEY || "";
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY || "";
const config: HardhatUserConfig = {
solidity: {

bytecodeHash: "ipfs", // Required for Sourcify verification
},
},

Hardhat 3 验证
验证命令可能会显示错误消息，但这通常是误导性的 —— 合约通常已在 Sourcify 和 MonadScan 上成功验证。请查看浏览器链接以确认验证情况。
hardhat3-monad 模板已预配置为在 MonadVision（Sourcify）和 Monadscan（Etherscan）上都验证合约。Hardhat 3 使用不同的配置结构，采用 verify 键和 chainDescriptors。如果您使用该模板，您的 hardhat.config.ts 应该已经包含：import hardhatToolboxViemPlugin from "@nomicfoundation/hardhat-toolbox-viem";
import { configVariable, defineConfig } from "hardhat/config";
import "dotenv/config";
export default defineConfig({
plugins: [hardhatToolboxViemPlugin],
