How to Authenticate Users with WalletConnect

Before the Start

You can start this tutorial if you already have a NextJS dapp with MetaMask functionality.

Configuring the WalletConnect Connector

  1. Open thepages/signin.jsx file and add WalletConnectConnector as a connector to connectAsync(). You should have your Project ID for the WalletConnect configuration and replace xxx with it in the code below.
import { WalletConnectConnector } from "wagmi/connectors/walletConnect";
import { signIn } from "next-auth/react";
import { useAccount, useConnect, useSignMessage, useDisconnect } from "wagmi";
import { useRouter } from "next/router";
import { useAuthRequestChallengeEvm } from "@moralisweb3/next";

function SignIn() {
const { connectAsync } = useConnect({
connector: new WalletConnectConnector({
options: { projectId: "xxx", showQrModal: true },
const { disconnectAsync } = useDisconnect();
const { isConnected } = useAccount();
const { signMessageAsync } = useSignMessage();
const { requestChallengeAsync } = useAuthRequestChallengeEvm();
const { push } = useRouter();

const handleAuth = async () => {
if (isConnected) {
await disconnectAsync();

const { account, chain } = await connectAsync();

const { message } = await requestChallengeAsync({
address: account,

const signature = await signMessageAsync({ message });

// redirect user after success authentication to '/user' page
const { url } = await signIn("moralis-auth", {
redirect: false,
callbackUrl: "/user",
* instead of using signIn(..., redirect: "/user")
* we get the url from callback and push it to the router to avoid page refreshing

return (
<h3>Web3 Authentication</h3>
<button onClick={handleAuth}>Authenticate via WalletConnect</button>

export default SignIn;

Testing the WalletConnect Connector

Visit http://localhost:3000/signin to test authentication.

  1. Click on Authenticate via WalletConnect:

Sign In Page

  1. Scan the QR code with your wallet:

WalletConnect Modal

  1. Connect your wallet:

TrustWallet Connect - Confirm

  1. Sign the message:

TrustWallet Message - Signing

  1. Visit http://localhost:3000/user to test the user session's functionality:
  • When a user is authenticated, we show the user's info on the page.
  • When a user is not authenticated, we redirect to the /signin page.
  • When a user is authenticated, we show the user's info on the page, even refreshing after the page. (Explanation: After Web3 wallet authentication, the next-auth library creates a session cookie with an encrypted JWT [JWE] stored inside. It contains session info [such as an address and signed message] in the user's browser.)
