NOVAWALLET
Nova Digital Inc. engaged Windson as Mobile App Architects to deliver a high-fidelity fintech app — built on React Native, Node.js, SQL.
The client wanted a cross-platform cryptocurrency wallet that had native performance (120Hz smooth rendering) and robust, hardware-level security. The wallet needed multi-signature support, real-time transaction ledger updates, and custom charts that didn't stutter on low-end devices.
We engineered a custom React Native application leveraging Skia for hardware-accelerated charting. Security is managed via hardware-bound biometric authentication using iOS Secure Enclave and Android KeyStore. We developed a Node.js sync server using PostgreSQL and Redis for real-time ledger verification.
Native-grade speed and vault-grade security — one codebase, shipped to both stores.
