# Wallet Integration Summary

## What Was Implemented

### 1. Top Up Wallet via Paystack
Users can now top up their wallet using the same payment flow as exchange orders:
- Click "Top Up" button on dashboard
- Enter amount (minimum ₵10.00)
- Redirected to payment confirmation page
- Proceed to Paystack payment gateway
- On successful payment, wallet is credited automatically
- Transaction recorded in `wallet_transactions` table

### 2. Exchange Orders Credit Wallet
When admin marks an exchange order as "completed":
- CNY amount is automatically added to user's wallet balance
- Creates wallet transaction record (type: topup, method: exchange)
- Sends notification to user about completed exchange
- Reference format: EXC-{ORDER_NUMBER}

### 3. Withdraw Funds
Users can withdraw funds from their wallet:
- Enter amount and account details
- Funds immediately deducted from wallet
- Admin processes withdrawal manually
- Transaction tracked with WTH-{UNIQUE_ID} reference
