Cryptocurrency exchange architecture outlines the technical blueprint for building a secure, scalable, and efficient trading platform. Core components include a trading engine, user interface, wallet system, KYC/AML module, database, and admin dashboard. The architecture ensures seamless integration between components, real-time transaction processing, and secure fund custody. Layered security with encryption, firewalls, and DDoS protection is critical. Whether centralized or decentralized, the architecture must support high performance, fault tolerance, and regulatory compliance. It is the foundation for delivering fast, reliable, and secure crypto trading experiences.
