Enterprise

OPEX is developed based on an enterprise mindset. With a systemic approach and concerns about customizability, extendability, and maintainability.

Modular

OPEX is made based on separate modules. (Matching engine, deposit, KYC, ...) combinations of these modules can make different products. Is there anything missing? You can create a new module for the project or hire us to do so.

Scalable

Yes! We love microservices. It makes OPEX scalable. You can run different instances of a module to handle more loads. In other words, it's meaningless to ask about TPS here; it depends on your resources!
