ABOUT THE CLIENT
The client is the team behind Ouinex, a centralized cryptocurrency exchange (CEX). They wanted to extend platform access beyond the standard browser interface by giving users a way to manage their accounts and interact with trading-related features directly inside Telegram — without lowering the security or compliance bar a CEX is held to. The goal was an additional access channel, not a stripped-down companion app.
Challenge
The project required replicating critical CEX functionality inside the constraints of the Telegram ecosystem: secure authentication, account balance synchronization, deposits, withdrawals, compliance workflows, and referral mechanics. The core difficulty was architectural rather than visual. The system had to securely connect Telegram identities to centralized exchange accounts, maintain real-time data integrity across the messaging interface and the exchange backend, and preserve compliance guarantees — KYC and two-factor authentication — that a crypto exchange cannot relax just because the user arrived through a chat client.
