Implementing SIWE with WalletConnect's AppKit in Next.js

Web3 authentication is evolving, and Sign In With Ethereum (SIWE) is leading the charge. This article explores how to implement SIWE in a Next.js application using WalletConnect's AppKit, focusing on the "One Click Auth" feature and securing API routes with JWT tokens.

Understanding SIWE and AppKit

Sign In With Ethereum (SIWE) is a standardized authentication method (EIP-4361) that allows users to prove ownership of their Ethereum address through a cryptographic signature. WalletConnect's AppKit simplifies this process with its "One-Click Auth" feature, enhancing both security and user experience.

Implementation Steps

  1. Set up: Install necessary dependencies:
   yarn add @web3modal/siwe next-auth
Enter fullscreen mode Exit fullscreen mode
  1. Configure SIWE Client: Create a SIWE client configuration file to handle message parameters, nonce generation, and session management.

  2. Set Up API Route: Implement a NextAuth handler to manage authentication, verifying signatures and creating sessions using JWT tokens.

  3. Secure API Routes: Use a Next.js middleware to protect specified routes, requiring authentication for access and passing the user's wallet address to API routes.

Read this article for more details about the steps aforementioned.

Benefits

  • Enhanced security through cryptographic signatures
  • Improved user experience with one-click authentication
  • Seamless integration with Next.js applications
  • Robust API route protection using JWT tokens

By implementing SIWE with WalletConnect's AppKit, developers can create secure, user-friendly decentralized applications that leverage the power of Web3 authentication.
