Security Model
Built secure
from the ground up
Your private keys are encrypted at rest, never uploaded, and all signing happens entirely on your device.
Keystore-Backed Storage
Secrets are protected by Android Keystore primitives — hardware-backed encryption where supported by the device.
No Key Upload
Private keys and mnemonics stay on-device. The app only contacts blockchain nodes for data — never for key custody.
Local Transaction Signing
All transaction signing happens in-app. Sensitive key material never reaches remote services.
PIN Hardening
PBKDF2 key derivation with per-account salt and progressive rate limiting to resist brute-force attacks.
Session Auto-Lock
Configurable inactivity timeout. Optional PIN gate for sensitive actions reduces risk on unattended devices.
Backup & Recovery
Export your 24-word BIP39 mnemonic or raw private key locally. Full control — no cloud backup dependency.
