Metamask Address Exercise

Ethereum Game Programming
#41

Instead of Web3.js I use Ethers.js
Currently I have a Button the user needs to press to establish a conncetion between the game and the wallet.

let provider, signer, instance, user, address;
const contractAddress = "YOUR_CONTRACT_ADDRESS";

async function login() {
    provider = new ethers.providers.Web3Provider(window.ethereum);
    await provider.send("eth_requestAccounts", []);
    user = provider.getSigner();
    address = await user.getAddress();
    instance = new ethers.Contract(contractAddress, abi, provider);
    signer = instance.connect(user);
};

const walletButton = document.querySelector('#enableWeb3');
walletButton.addEventListener('click', async() => {
    //Will Start the metamask extension
    if (window.ethereum) { 
        walletButton.innerHTML = "Connecting";
        await login();
        walletButton.innerHTML = address;
    } else {
        walletButton.innerHTML = "FAILED TO CONNECT WEB3; Install Web3 Provider!";
    };
});
