Hey folks 👋

I’m currently researching the backend architecture required for a cryptocurrency exchange platform, and it’s honestly more complex than I expected.

Here are a few pain points I came across:

Order matching and latency: Matching engines must process thousands of transactions per second with sub-millisecond latency.
Wallet management: Handling deposits and withdrawals securely across multiple chains adds extra layers of complexity.
Data synchronization: Keeping real-time balance and trade data consistent across microservices is tricky.
Compliance modules: Integrating KYC/AML verification without affecting UX is a major challenge.

Curious to know:

Has anyone here built or tested such scalable trading systems?
How would you design the data layer for high-frequency trade events?
Any favourite tools or frameworks you’d use for this type of build?

Looking forward to your tech insights — always fun to learn from other builders

You’re right, building a cryptocurrency exchange backend can be really challenging. For order matching, using an in-memory engine with event-driven tools like Kafka can help improve speed and reliability. Wallet management works best when you separate hot and cold wallets with auto reconciliation. For data consistency, event sourcing with CQRS is a solid approach. You can also look into Fourchain, a cryptocurrency exchange development company that offers scalable backend solutions for trading platforms, wallet management, and multi-chain integration.
