## What is UPay?

UPay is a self-custody digital asset wallet powered by a Rust security core engine, built for TRON network users.

Unlike typical wallets, UPay's key management, transaction signing, and secure communication modules are built entirely from scratch in Rust, delivering native-level security and performance.

[Rust Security Core Engine]
- Private key signing logic written in Rust, not JavaScript/Dart
- ECDH key exchange + HMAC request signing to prevent MITM attacks
- DNS-over-HTTPS + SSL Certificate Pinning to block network hijacking
- All sensitive operations completed locally on device, private keys never leave your phone

[Full Self-Custody]
- No account registration required, no phone number or email needed
- Mnemonic stored only on your device, inaccessible to UPay
- HD wallet architecture with multi-address support

[TRON Ecosystem Focus]
- USDT (TRC-20) and TRX asset management
- Real-time on-chain balance and full transaction history
- QR code scanning for quick transfers

[Multi-Layer Security]
- Face ID / Fingerprint + security password dual verification
- Configurable auto-lock timeout
- Mnemonic encrypted via system-level secure storage

[Multi-Language]
- Traditional Chinese, Simplified Chinese, English
