Hey everyone. Sharing an overview of a production-ready FinTech and crypto processing architecture we've built for high-load platforms. It combines a spot trading engine, multi-currency support, automated virtual card issuing integration (Payb), and a secure merchant API into a unified system designed to run independently on standard Linux infrastructure.
Core Architectural Modules:
- Virtual Card Management: Automated card emission engine (Visa/Mastercard) with real-time card controls, balance updates, and multi-tier user limits.
- Spot Trading Core: Real-time order books, TradingView integration, limit/market order processing, and automated ticker synchronization via external exchange feeds (Binance API).
- Multi-Asset Wallet Backend: Native tracking for 13 major assets (USD, USDT, BTC, ETH, BNB, SOL, XRP, ADA, DOGE, TON, TRX, LTC, LINK) with base currency conversion logic.
- Merchant Gateway API: Checkout protocol utilizing HMAC-SHA256 request signing, secure webhook dispatchers, and automated invoice verification.
System Specifications & Security:
- Environment: PHP 8.1+ with strict bcmath handling for precise financial calculations, MariaDB/MySQL storage engine, Nginx/Apache.
- Concurrency & Safety: Mitigation of race conditions through database row-level locking mechanisms, Master PIN authorization layers for internal transfers, and protected code distribution via IonCube.
- Hardware Profile: Optimized for standard VPS nodes (min. 2 vCPU, 2 GB RAM).
