Financial & Payments

First Croatian cryptocurrency trading platform for Bitcoin, Litecoin, and Ethereum. 

We upgraded the first basic version of the exchange to a more robust infrastructure and much better UI and UX. A lot of back-office improvements were made including automated deposits and withdrawals of FIAT (USD) where we had to make an integration with our bank system. 

The trading engine which matches user orders is fully custom-made. We also maintain the exchange’s hot and cold storage wallets which require high-security standards.

An online Crypto to Crypto and Crypto to FIAT exchange and a back office system for physical exchange stores in Croatia. 

We built the product from scratch and worked on all development lifecycle steps from product design, UX design, software development, QA, and maintenance.

The system is delicate because of its integrations with other Crypto exchanges (Bitstamp, Binance, Bitfinex) where it performs live trades every second. We worked a lot on system optimization and security. The main goal was to make the system stable, efficient, and bug-proof in order to generate maximum profit out of each trade.
