User Management System for AITBC Trade Exchange

Overview

The AITBC Trade Exchange now includes a complete user management system that allows individual users to have their own wallets, balances, and transaction history. Each user is identified by their wallet address and has a unique session for secure operations.

Features Implemented

1. User Registration & Login

• Wallet-based Authentication: Users connect with their wallet address
• Auto-registration: New wallets automatically create a user account
• Session Management: Secure token-based sessions (24-hour expiry)
• User Profiles: Each user has a unique ID, email, and username

2. Wallet Management

• Individual Wallets: Each user gets their own AITBC wallet
• Balance Tracking: Real-time balance updates
• Address Generation: Unique wallet addresses for each user

3. Transaction History

• Personal Transactions: Each user sees only their own transactions
• Transaction Types: Buy, sell, deposit, withdrawal tracking
• Status Updates: Real-time transaction status
