-# Authentication Module
-
-This module provides JWT-based authentication for the StellarAid API.
-
-## Features
-
-- User registration with email and wallet address
-- User login with email/password
-- JWT token generation and validation
-- Protected routes using JWT authentication
-- Password hashing with bcrypt
-
-## Endpoints
-
-### POST /auth/register
-Register a new user
-
-**Request Body:**
-```json
-{
-  "email": "user@example.com",
-  "password": "password123",
-  "firstName": "John",
-  "lastName": "Doe",
-  "walletAddress": "GABC123..."
-}
-```
-
-**Response:**
-```json
-{
-  "accessToken": "jwt-token-string",
-  "user": {
-    "id": "1",
-    "email": "user@example.com",
-    "firstName": "John",
-    "lastName": "Doe",
-    "walletAddress": "GABC123..."
-  }
-}
-```
-
-### POST /auth/login
-Login with existing credentials
-
-**Request Body:**
-```json
-{
-  "email": "user@example.com",
-  "password": "password123"
-}
-```
-
-**Response:**
-```json
-{
-  "accessToken": "jwt-token-string",
-  "user": {
-    "id": "1",
-    "email": "user@example.com",
-    "firstName": "John",
-    "lastName": "Doe",
-    "walletAddress": "GABC123..."
-  }
-}
-```
-
-### GET /auth/profile
-Get current user profile (requires JWT token)
-
-**Headers:**
-```
-Authorization: Bearer <jwt-token>
-```
-
-**Response:**
-```json
-{
-  "sub": "1",
-  "email": "user@example.com",
-  "walletAddress": "GABC123..."
-}
-```
-
-## Environment Variables
-
-Add these to your `.env` file:
-
-```env
-JWT_SECRET=your-super-secret-jwt-key-here-change-in-production
-JWT_EXPIRES_IN=1d
-```
-
-## Dependencies
-
-- `@nestjs/jwt` - JWT token handling
-- `@nestjs/passport` - Authentication middleware
-- `bcrypt` - Password hashing
-- `passport-jwt` - JWT strategy for Passport
-- `class-validator` - Request validation
-
-## Security Notes
-
-- Passwords are hashed using bcrypt with 10 salt rounds
-- JWT tokens are signed with a secret key
-- All endpoints use validation decorators
-- Current implementation uses in-memory storage (replace with database in production)
-
-## Testing
-
-Run the authentication tests:
-```bash
-npm run test auth
-```
-
-## Next Steps
-
-1. Replace in-memory storage with a proper database
-2. Add user roles and permissions
-3. Implement refresh tokens
-4. Add email verification
-5. Add rate limiting for auth endpoints
-6. Implement proper error handling and logging
