1. 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.

For traders

REX offers live order books, fast execution, instant conversion and intuitive mobile apps.

For issuers

It provides a regulated friendly environment with full KYC and AML, audit trails and transparent reporting.

For partners

It exposes documented REST and WebSocket APIs that make it possible to connect market making tools, analytics and external platforms without giving up security.

2. Core trading experience

The exchange has been designed to deliver a trading experience that feels familiar to anyone who has used a modern CEX, while being accessible to first time investors.

Spot trading

Spot trading is at the core of REX. Users can place market and limit orders on supported pairs, monitor real time price updates and view the depth of the order book to understand liquidity before entering a trade. Live charts and indicators, powered by a charting component similar to TradingView, are integrated directly into the trading page so that users do not need to switch tools to analyse price action.

Crypto conversion

For users who prefer a simpler interface, crypto conversion offers a one click way to swap one asset for another at prevailing market rates. This is particularly useful for portfolio rebalancing, moving between stablecoins and volatile assets or simplifying exposure to a single base asset without stepping through the full trading screen.

Market data

Market data is delivered in real time through WebSocket connections. The order book, last traded price, 24 hour high and low, percentage change and volume all update without requiring a page refresh, so traders always operate on current information. Historical analytics and PnL calculations help users understand realised and unrealised profits or losses over time.

3. Custody, wallets and fund safety

Fund security is central to the design of REX. The exchange uses a tiered custody model with segregated hot, warm and cold wallets. Small working balances are kept in hot wallets that are connected to the exchange engine for fast deposits and withdrawals. Larger balances are stored in warm and cold wallets that use multi signature schemes and offline signing for sensitive movements. This structure allows REX to handle day to day operations without exposing the majority of user funds to online risk.

Deposits are managed by blockchain daemons that watch wallets for incoming transactions and route funds into the appropriate tier based on thresholds. Withdrawals are checked against limits and available balances, with smaller withdrawals processed automatically from hot wallets and larger ones requiring additional approval and manual signing through warm or cold custody workflows.

Key management is handled using enterprise grade secret management tools such as HashiCorp Vault, so private keys and API secrets are never stored in code repositories or flat configuration files. Vault access is tightly controlled and monitored. On top of this, REX maintains a SAFU style reserve fund that can be used to reimburse users in the unlikely event of a security incident, aligning the platform with best practice among leading centralized exchanges.

4. KYC, AML and account lifecycle

REX is built with full regulatory alignment in mind. From the first step of account creation, security and compliance are woven into the user journey. Users register with secure email and password flows that use bcrypt hashing, then are strongly encouraged to enable two factor authentication to protect account access.

Know Your Customer and Anti Money Laundering checks are conducted through integrated identity verification providers such as KYCAID or Sumsub. The exchange supports document verification for passports and identity cards, proof of address, facial recognition checks and address validation. Verification status is updated in real time inside the user profile, and double verification logic is used to ensure a high degree of accuracy before accounts are fully approved.

KYC documents and personal data are stored in encrypted object storage, with access restricted to authorised services only. Regional controls and geofencing make it possible to restrict access for jurisdictions where trading is not permitted, and role based access ensures that administrative actions are carefully controlled and logged. KYC status is also surfaced in the admin console, where compliance staff can review cases, manage escalations and handle re verification when documents expire.

5. Liquidity and matching engine

The trading heart of REX is its matching engine and liquidity management framework. Orders from users are routed through a dedicated engine that can match buys and sells at high speed while maintaining strict consistency for balances and trade history. Real time PnL calculations and market price tracking are integrated into the trade processing pipeline so that users see accurate results almost immediately after execution.

Liquidity is managed through a dedicated liquidity portal. This portal allows administrators to configure trading pairs, adjust fees, and decide whether a particular market will use external liquidity from a tier one venue or rely on internally managed liquidity. REX can integrate with established third party liquidity engines to give users deep order books and tight spreads, while also supporting its own liquidity where RVA decides to operate proprietary markets. Market making bots can be connected to keep spreads competitive and maintain orderly books.

This flexible design means that REX can quickly list new asset pairs, including tokenised real world assets that are unique to the RVA ecosystem, without sacrificing execution quality. Admins can monitor volume and order book depth, then fine tune liquidity strategies as the market grows.

6. Platform architecture and performance

The architecture diagram shows a modular, microservice style platform running on Kubernetes, with each major responsibility separated into its own service. A managed Kubernetes cluster handles container orchestration, self healing and horizontal scaling, so the exchange can scale up across multiple nodes as trading volume grows.

Messaging between services is handled by RabbitMQ, which decouples components such as trade execution, notification dispatch and blockchain daemons. Redis is used for ultra fast caching of order books and session data, which keeps the trading interface responsive even under load.

Relational databases like MySQL or PostgreSQL store core structured data such as user profiles, balances and trade history, while a time series database like InfluxDB powers analytics and monitoring.

Scalability

The Kubernetes based architecture allows REX to scale horizontally, adding more nodes and services as trading volume increases. This ensures consistent performance even during peak trading periods.

Monitoring

Monitoring and observability are provided by Prometheus and Grafana, which collect metrics such as latency, error rates and throughput across the stack. This allows operations teams to see issues before they affect users and to plan capacity proactively.

Disaster recovery

Disaster recovery is supported by backup strategies and a plan that covers scenarios such as hardware failure, data corruption or denial of service attacks, so that the platform can recover to a safe state if needed.

7. Mobile apps and user experience

REX mobile apps are built with React Native, giving a unified codebase for both iOS and Android while still delivering a native feeling experience. From a UX perspective they mirror the core exchange functionality with an interface optimised for smaller screens.

Onboarding is streamlined. Users can register with email and password, enable biometric login on supported devices and set up two factor authentication. The KYC process is accessible directly from the app, with document upload, selfie capture and live status updates. Once verified, users can access the full trading experience from their phone.

The Markets section provides live charts, market depth and order books for trading pairs, watchlists for favourite assets, search and filtering, and configurable price alerts. Balances are presented in a Funds view that shows spot, staked and locked funds, with clear transaction history for deposits, withdrawals, trades and rewards. Deposit and withdrawal flows include QR code support, multiple network options where relevant and address whitelisting to reduce the risk of sending to the wrong destination.

Trading on mobile supports market, limit and stop limit orders, as well as quick buy and sell actions for users who prefer a simplified interface. Real time portfolio tracking and performance metrics help users keep an eye on their positions even when away from a desktop terminal.

8. APIs and integrations

RVA Exchange exposes REST and WebSocket APIs for partners who want to integrate trading, market data or account functionality into external systems. These APIs are suitable for market makers, quantitative traders, portfolio trackers and institutional clients who need programmatic access.

REST endpoints provide operations such as retrieving balances and order history, placing and cancelling orders, and querying recent trades. WebSocket connections deliver real time updates for order books and trades, which is essential for building low latency trading strategies or live dashboards.

API keys are managed securely through the exchange account interface and stored using Vault backed secret management, so they are never exposed in plaintext. Rate limits and permission scopes are applied to protect the platform and help clients design integrations that are both powerful and safe.

9. Security features and operational resilience

Security for REX is multi layered. At the infrastructure level, the platform runs behind DDoS protection from a provider such as Cloudflare, shielding it against common volumetric and application layer attacks. At application level, regular security audits, code reviews and penetration tests are scheduled to identify and remediate vulnerabilities before they can be exploited.

Sensitive data such as passwords, API keys and private keys are handled using best practice. Passwords are hashed using modern algorithms, keys and secrets are stored in Vault, and KYC documents in encrypted storage. Access to administrative consoles is protected by role based access control and secured network paths. Background workers that process deposits, withdrawals and synchronisation tasks are designed to be idempotent, so that failures do not result in inconsistent balances.

On the user side, two factor authentication, address whitelisting, withdrawal limits and clear notifications for key account events help reduce the risk of account takeover or social engineering. Push notifications and email alerts confirm deposits, withdrawals, login attempts and important security events, so that users can respond quickly if something looks suspicious.

All of this is tied together by operational practices that include change management, logging and audit trails. Every significant administrative action and system change is recorded, which supports both internal governance and external audits.
