Getting WETH from ETH on Hardhat Local Network

Question

I have a localhost Hardhat Network running but I need to convert Fake ETH on it into WETH. How can I do this?

Answer 1

I think the easiest way to do this is to create an ERC20 called WETH. Something like:

// SPDX-License-Identifier: UNLICENSED
pragma solidity 0.8.4;

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

contract WETHToken is ERC20 {
    constructor() ERC20("Wrapped ETHER", "WETH") {
        _mint(<msg.sender or your address>, 9999 ether);
    }
}

So when you npx hardhat node, you'll have to deploy that contract.
