Secure Mobile Crypto Wallet

CASE STUDY

Objective

Build a non-custodial mobile wallet tailored for mainstream crypto users in Asian markets, featuring multi-chain account abstraction and biometric key protection.

Architecture Highlights

  • Hardware Keystore Integration: Private keys never touch JavaScript memory; signing is offloaded to iOS Secure Enclave and Android Keystore.
  • Offline Transaction Signing: Air-gapped QR transaction authorization for cold-storage mode.
  • Lightweight SPV Client: Instant block header verification without downloading gigabytes of state.
