Overview and positioning
RVA Exchange is a centralized spot trading venue where users can buy, sell and convert supported cryptocurrencies, including tokenised real world assets and native RVA instruments, through a single account. At architecture level it is a classic CEX: orders are matched off chain, balances are held in secure wallets and settlements are reconciled against blockchain nodes and liquidity providers.
REX sits alongside RVA Wallet and RVA SmartChain as the execution layer for secondary market trading. Wallet users can move assets between non custodial wallets and their exchange account, then trade on REX with the kind of performance and reliability they expect from a professional centralized exchange.

Core trading experience
Spot Trading
Market and limit orders on supported pairs, real time price updates and order book depth. Live charts integrated directly into the trading page.
Crypto Conversion
One click way to swap assets at prevailing market rates. Useful for portfolio rebalancing without stepping through the full trading screen.
Market Data
Real time WebSocket connections for order book, last traded price, and 24h stats. Updates without page refresh for accurate information.
Custody, wallets and fund safety
Fund security is central to REX. The exchange uses a tiered custody model with segregated hot, warm and cold wallets. Small working balances are kept in hot wallets for fast operations, while larger balances are stored in warm and cold wallets using multi-signature schemes.

Deposits are managed by blockchain daemons watching for transactions. Withdrawals are checked against limits and balances, with larger amounts requiring manual signing. State transitions are controlled by SQL based daemons to ensure consistency.
Key management uses HashiCorp Vault, ensuring private keys are never stored in plaintext. Additionally, REX maintains a SAFU style reserve fund for emergency protection.

KYC, AML and account lifecycle
REX is built with regulatory alignment in mind. Users verify identity through providers like KYCAID or Sumsub (passports, ID cards, liveness checks). Data is stored in encrypted object storage. Regional controls restrict access based on jurisdiction. The admin console allows compliance staff to manage escalations and re-verification.

Encrypted StorageLiquidity and matching engine
The matching engine processes orders at high speed while maintaining strict consistency. Real time PnL calculations are integrated into the pipeline. Liquidity is managed via a portal allowing admins to configure pairs, fees, and connect external liquidity providers or internal market making bots. This ensures deep order books and competitive spreads for all listed assets.
Platform architecture and performance
The platform runs on a modular, microservice architecture using Kubernetes for orchestration and scaling. Messaging is handled by RabbitMQ, decoupling trade execution from notifications and blockchain daemons.

Redis provides ultra-fast caching for order books. Relational databases (MySQL/PostgreSQL) store structured data, while InfluxDB handles time-series analytics.
