FastCoinExchange

Shortly after we delivered an MVP, our client asked us to start working on the full version of the product. As a result, we delivered a SaaS system that processes requests, orders, and transactions within seconds and integrates with external e-wallets and other exchange platforms, etc. Most importantly, the new platform architecture makes it vastly more flexible for both client-side and server-side changes as well as increases its processing speed and data safety.

This complex platform has its own fiat and cryptocurrency exchange functionality and is integrated with several external platforms. Thus, when the system doesn’t have enough resources to provide exchange services for individual clients, it serves as a broker and connects users with other exchange platforms. All orders are processed within seconds, so users always get the desired result and don’t need to go elsewhere. The advanced matching algorithm helps the system to find the best exchange offers for each order and makes sure that all users exchange bitcoins and other currencies within seconds and at the most profitable rate.

Our client already had a launched and functioning currency exchange platform written on PHP, but its monolithic architecture became too challenging to maintain and upgrade. We solved this problem by creating 13 microservices and dividing the main functionalities among them. Since orders, wallets, matching, supporting old clients, placing orders on external services, and other functionalities don’t have such tight connections as before, changing or even removing one of them won’t affect the others (which is nearly impossible in monolithic platforms).
