Core Technology Stack

Frontend Layer

• React Native (Solana-tailored build)
• Custom WebView Engine with privacy interceptors
• Local SQLite Database with AES-256 encryption
• Arcium MPC Client SDK for encrypted computation
• Minimal UI Components optimized for mobile

Backend Layer

• NestJS Server (lightweight API gateway)
• Firebase Firestore (encrypted settings sync only)
• Arcium MPC Network (search query anonymization)

Privacy & Security

• Local-First Architecture - critical data never leaves device
• End-to-End Encryption for all synced data
• Zero-Knowledge Design - backend never sees raw browsing data
