We developed a high-performance centralized crypto exchange with an integrated BNIX token used for governance and voting among platform owners. The platform supports spot and futures trading, fiat gateways, referral modules, and dynamic liquidity synchronized with Binance. Our team implemented a scalable microservice architecture, blockchain integration, and full DevOps automation within just five months.
Client and Vision
A client approached us with a request to develop a centralized crypto exchange that could be jointly managed by multiple stakeholders. To make this governance process transparent and efficient, we proposed creating a native BNIX token — used for voting and decision-making on key platform updates. This feature transformed the project into a tokenized governance ecosystem.
Goals and Key Features
Together with the client, we defined the core functionality of the exchange:
- Spot and futures trading
- BNIX token integration for governance
- Fiat payment gateway and instant swap module
- Referral system for influencers and partners
- Scalable architecture with self-hosted crypto nodes
Because the client planned for rapid market entry and growth, we decided to deploy our own crypto nodes and involve a senior DevOps engineer to set up full synchronization across networks.
To ensure liquidity, the exchange connects to Binance in real time if the internal balance becomes insufficient.
Planning and Design Phase
Our design team prepared over 200 UI layouts in Figma within three weeks — including dashboards, trading screens, partner portals, and admin panels.
The project was managed in YouTrack, divided into milestones under a hybrid Kanban/Scrum methodology for flexibility and speed.
During early discussions, we introduced an additional feature — a paid token listing system that allows new tokens to be added on a commercial basis, generating extra revenue for the platform.
Architecture
We implemented a microservice architecture where every core module — trading, deposits, KYC/AML, referrals, admin, and governance — runs independently with its own API.
The infrastructure was first deployed in AWS Cloud for stability, and later partially migrated to Hetzner to reduce operational costs by nearly 6x while maintaining reliability and scalability.
DevOps and Infrastructure
Our DevOps team launched a robust cloud infrastructure using AWS EC2 instances for each crypto node: BTC, ETH, LTC, XRP, TRON, and BNB.
As the blockchain data grew faster than expected, we built automatic scaling and monitoring using Prometheus and Grafana.
We set up a CI/CD pipeline in GitLab with separate staging and production environments and rollback protection.
Development Process
The backend was developed with Laravel and Node.js, the frontend with React.js, and blockchain logic on Solidity.
We used GitLab as our version control system, isolating each microservice for safer updates and parallel development.
During development, we encountered several challenges:
- XRP deposits were unstable, so we rebuilt the module using direct RPC connections, which fixed synchronization issues.
- The referral system required dynamic bonus logic for influencers — we created a dedicated analytics and reward module.
- The BNIX governance module allowed investors to create polls, vote with tokens, and automatically record results on-chain, providing a transparent decision-making mechanism.
