• Stellar Integration: Contract interaction and transaction handling
• Database: PostgreSQL for persistent data storage
• Authentication: JWT-based user authentication

Frontend (React/TypeScript)

• Modern UI: Responsive design with Material-UI
• Wallet Interface: Multi-signature transaction management
• Real-time Updates: WebSocket integration for live updates
• Security: Secure key management and transaction signing

🔧 Technology Stack

• Rust: Contract development language
• Soroban: Stellar smart contract platform
• WASM: WebAssembly compilation target

Backend

• Node.js: Runtime environment
• Express.js: Web framework
• TypeScript: Type-safe JavaScript
• PostgreSQL: Database
• Prisma: ORM
• Stellar SDK: Stellar blockchain integration

Frontend

• React: UI framework
• TypeScript: Type-safe development
