When it comes to crypto options trading exchange development, the tech stack needs to handle heavy trade volumes and real time execution. A strong backend can be built using languages like Java, C++, or Go for handling order matching and execution. Node.js and Python are also used for modular services and APIs. For the frontend, React or Angular can give traders fast and interactive dashboards. Databases such as PostgreSQL, MongoDB, or even Redis for caching are commonly used to manage large amounts of trading and user data. A reliable messaging system like Kafka or RabbitMQ is important for handling order queues and live feeds. Security libraries for encryption, two factor authentication, and wallet integration complete the stack.
