A full-featured cryptocurrency exchange platform, currently undergoing modernization to a service-oriented architecture.

• Trading Engine: Real-time order matching and execution.
• Wallet Management: Secure deposit and withdrawal processing.
• Currencies: Support for BTC, LTC, and fiat currencies (USD, EUR, RUB).
• User Dashboard: Customizable widgets for charts, order books, and history.
• Admin Panel: Comprehensive tools for user management, audit logs, and financial oversight.

• OKPay
• Perfect Money
• Yandex Money
• EgoPay (Legacy)

This project is currently being refactored from a legacy MVC structure to a modular, testable architecture.

The application now utilizes a service layer to decouple business logic from controllers:

• Services: PaymentService, UserService, AdminService handle core business logic.
• Payment Gateways: Adapter pattern implementation (PaymentGatewayInterface) allows easy switching and testing of payment providers.
• Infrastructure: centralized logging (Logger), audit trails (AuditLog), and request validation (RequestValidator).

1. Clone the repository

   git clone https://github.com/diannt/php_btc_exchange.git

2. Database Setup

   • Create a new database.
   • Import the schema from emonex.sql.
   • Update database credentials in config/config.php.

3. Configuration

   • Copy config/services.php (if not present) and configure payment gateway credentials.
   • Set environment variables for sensitive keys (recommended) or update config/services.php directly.

   Environment Variables:

   OKPAY_WALLET_ID=...
   OKPAY_API_PASSWORD=...
   PM_ACCOUNT_ID=...
   PM_PASS_PHRASE=...
   YM_ACCESS_TOKEN=...

• Audit Logging: Sensitive admin actions are recorded in logs/audit.log.
• Validation: Input validation is handled by RequestValidator to prevent injection and malformed data.
• Logging: Application errors and events are logged to logs/app.log.

We are actively moving legacy code to the new lib/ structure. When contributing:

1. Avoid adding logic to controllers/.
2. Use the Service classes in lib/Services/.
3. Implement new payment methods using PaymentGatewayInterface.
