SIWE Authentication Implementation

Authentication · Existing Codebase

Overview

Implemented a Sign-In with Ethereum authentication flow within an existing Web3 application as part of a technical assessment.

The Problem

Web3 applications need a way to authenticate users through wallet ownership without relying on traditional password-based authentication.

The Solution

Implemented the authentication flow: Wallet Connect → Challenge Generation → User Signature → Backend Signature Verification → Authenticated Session.

Key Features

  • Wallet connection flow
  • Challenge message generation
  • User signature collection
  • Backend signature verification
  • Authenticated session handling
  • Error handling
