Coinbase Exchange Design Interview Topics
courses and mock interviews.
The Coinbase exchange system design interview tests your ability to architect scalable, secure, and low-latency trading systems for millions of concurrent cryptocurrency transactions.
When to Use
This interview format appears for backend and full-stack engineers designing components such as order books, wallets, and trade pipelines to ensure real-time performance and reliability.
Example
Suppose you’re asked to design a simplified Coinbase exchange where users can trade Bitcoin and Ethereum. You’d describe how the matching engine pairs orders, updates balances, and ensures ACID guarantees across distributed systems.

Why Is It Important
Coinbase systems must ensure scalability, fault tolerance, and security under volatile market loads. Designing for these constraints demonstrates deep understanding of distributed architecture and data integrity.
Interview Tips
Discuss components like user service, wallet service, order matcher, and trade ledger. Clarify data flow, latency targets, and fault recovery. Visualize APIs and trade propagation paths.
Trade-offs
Choosing between speed and durability is critical—using in-memory order books boosts latency but may risk data persistence if nodes fail.
Pitfalls
Avoid skipping security and consistency concerns or ignoring scaling during traffic spikes. Coinbase values engineers who design with real-world reliability in mind.
