Technologies We Used

The application leverages a sophisticated technology stack combining cross-platform frameworks, high-performance backend systems, and robust blockchain protocols. React Native serves as the foundation for mobile development, while ReactJS and NextJS power the web and extension interfaces. The backend infrastructure utilizes NodeJS for API services and real-time data processing, with MongoDB managing flexible data storage requirements. For decentralized storage of NFT metadata and assets, we integrated IPFS. Blockchain connectivity encompasses multiple networks including Ethereum, BNB Chain, Polygon, TON, and Bitcoin, with REST API and WebSocket connections ensuring reliable real-time data synchronization. The entire ecosystem is deployed and managed on Amazon Cloud Services for enterprise-grade reliability and scalability.
