1xBet App Architecture: Technical Overview
Technical overview of 1xBet App architecture: client-server design, native Android (Kotlin/MVVM) and iOS (Swift) apps, REST API + WebSocket communication, microservices backend, caching strategies, and security layers including TLS 1.3 and certificate pinning.
Last updated: January 27, 2026
Architecture Overview
The 1xBet App uses a modern client-server architecture with the following key components:
| Layer | Purpose | Technologies |
|---|---|---|
| Client (Mobile App) | User interface, local storage | Native Android/iOS, Hybrid components |
| API Gateway | Request routing, authentication | REST API, WebSocket |
| Backend Services | Business logic, data processing | Microservices architecture |
| Data Layer | Persistence, caching | Databases, Redis cache |
| External Services | Payments, odds feeds, streaming | Third-party integrations |
Client Architecture
Android App
- Language: Kotlin with Java components
- Min SDK: API 21 (Android 5.0)
- Architecture: MVVM (Model-View-ViewModel)
- DI: Dagger/Hilt for dependency injection
- Networking: Retrofit + OkHttp
- Local Storage: Room database, SharedPreferences
iOS App
- Language: Swift with Objective-C legacy
- Min iOS: iOS 12.0
- Architecture: MVVM + Coordinator pattern
- Networking: URLSession, Alamofire
- Local Storage: Core Data, UserDefaults, Keychain
Shared Components
- WebView for dynamic content (promotions, some games)
- Push notification handlers
- Biometric authentication modules
- Analytics and crash reporting
Communication Protocols
| Protocol | Use Case | Details |
|---|---|---|
| HTTPS/REST | Standard requests | Account, history, settings, payments |
| WebSocket | Real-time updates | Live odds, bet status, notifications |
| Push (FCM/APNs) | Background notifications | Bet results, promotions, alerts |
| HLS/DASH | Live streaming | Video content delivery |
Backend Services
The backend uses a microservices architecture:
| Service | Responsibility |
|---|---|
| Auth Service | Login, registration, 2FA, session management |
| Account Service | Profile, settings, verification status |
| Betting Service | Bet placement, settlement, history |
| Odds Service | Real-time odds, market data |
| Payment Service | Deposits, withdrawals, transactions |
| Casino Service | Game integration, RNG, results |
| Notification Service | Push, email, SMS delivery |
| Content Service | Promotions, static content, localization |
Data Flow
Bet Placement Flow
- User selects bet — App validates locally
- Request to API — Encrypted HTTPS request
- API Gateway — Auth check, rate limiting
- Betting Service — Validates odds, balance, limits
- Confirmation — Bet ID returned to app
- Real-time updates — WebSocket for status changes
Live Odds Flow
- User opens event — WebSocket connection established
- Odds feed — Server pushes updates
- UI update — App reflects changes instantly
- Bet submission — Current odds validated server-side
Security Architecture
- Transport: TLS 1.3 for all communications
- Authentication: JWT tokens with short expiry
- Storage: Encrypted local storage (AES-256)
- Biometrics: Secure enclave (iOS) / Keystore (Android)
- Certificate pinning: Prevents MITM attacks
- Obfuscation: Code protection against reverse engineering
Caching Strategy
| Data Type | Cache Location | TTL |
|---|---|---|
| User profile | Local DB | Until logout |
| Static content | Local + CDN | 24 hours |
| Odds data | Memory only | Real-time (no cache) |
| Bet history | Local DB | Sync on demand |
| Images/assets | Disk cache | 7 days |
Performance Considerations
- Lazy loading: Content loaded on demand
- Image optimization: WebP format, responsive sizes
- Request batching: Multiple requests combined
- Offline support: Basic functionality without internet
- Background sync: Data synced when connection restored

Architecture FAQ
What programming languages does 1xBet App use?
Android: Kotlin with some Java legacy components. iOS: Swift with Objective-C legacy. Both apps use MVVM architecture pattern. The backend uses microservices architecture with various languages depending on service requirements.
How does 1xBet App handle real-time updates?
Real-time updates (live odds, scores, bet status) use WebSocket connections for instant push updates. REST API handles standard request-response operations. Push notifications (FCM/APNs) deliver background alerts when the app is closed.
What is 1xBet App backend architecture?
The backend uses microservices architecture with separate services for Auth, Account, Betting, Odds, Payments, Casino, Notifications, and Content. Services communicate through API Gateway with load balancing and rate limiting.
How does 1xBet App cache data?
User profile: local DB until logout. Static content: local + CDN with 24h TTL. Odds data: memory only (real-time, no cache). Bet history: local DB with on-demand sync. Images: disk cache with 7-day TTL.
What security measures are in 1xBet App architecture?
TLS 1.3 for all communications, JWT tokens with short expiry, AES-256 encrypted local storage, biometric authentication via Secure Enclave (iOS) / Keystore (Android), certificate pinning to prevent MITM attacks, and code obfuscation.
