import type { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox-viem";
import { vars } from "hardhat/config";

const config: HardhatUserConfig = {
solidity: "0.8.28",
...
networks: {
...
monadTestnet: {
url: vars.get("MONAD_RPC_URL"),
accounts: [vars.get("PRIVATE_KEY")],
chainId: Number(vars.get("MONAD_CHAIN_ID")),
},
...
},
};

export default config;

or use this

import * as dotenv from "dotenv";
import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";

dotenv.config();

const config: HardhatUserConfig = {
solidity: "0.8.28",
networks: {
monadTestnet: {
url: process.env.MONAD_RPC_URL || "https://testnet-rpc.monad.xyz",
accounts: process.env.PRIVATE_KEY ? [process.env.PRIVATE_KEY] : [],
chainId: 10143, // Chain ID Monad Testnet
},
},
};

export default config;

edit your data with nano .env and last change pragma solidity to 0.8.28
