FuseBox Login using MetaMask

In this tutorial, we will guide you through the process of implementing user authentication using MetaMask, ethers.js, and FuseBox Web SDK in a decentralized application (DApp). This tutorial assumes you have a basic understanding of JavaScript, Ethereum, and Web3 development.

Prerequisites:

• Basic knowledge of JavaScript
• MetaMask wallet extension installed in your browser
• FuseBox Web SDK API Key

Implementing the Connection Logic

import { FuseSDK } from "@fuseio/fusebox-web-sdk";
import { ethers } from "ethers";

const connect = async () => {
  let signer = null;
  let provider;

  if (window.ethereum == null) {
    console.log("MetaMask not installed; using read-only defaults");
    provider = ethers.getDefaultProvider();
  } else {
    provider = new ethers.BrowserProvider(window.ethereum);
    signer = await provider.getSigner();

    const apiKey = "YOUR_API_KEY"; // Replace with your FuseBox API key
    const fuseSDK = await FuseSDK.init(apiKey, signer);

    console.log(`Logged in, ${fuseSDK.wallet.getSender()}`);
    // Perform additional actions after successful login, e.g., update UI
    setLoggedIn(true);
    console.log(loggedIn);
  }
};

connect();

Make sure to replace "YOUR_API_KEY" with your actual FuseBox API key.
