Keep: FROST Nostr Signer
FROST threshold signer and Nostr event signer for Android
新版本 1.2.0
The co-signing prompt now shows which request is asking to sign, and marks that label as unverified when nothing has proven it, so a name on its own cannot suggest the request was checked. Random number generation that cannot reach a trusted source now stops the operation instead of quietly continuing with a weaker one. A legacy key share is erased only after a copy is confirmed stored. Stored values are bound to the key they were saved under, so a value cannot be read back under a different key
Keep is a FROST (Flexible Round-Optimized Schnorr Threshold Signatures) threshold signing app and dedicated Nostr event signer for Android. It lets you hold FROST key shares on your phone and sign Nostr events without any single device ever holding the full private key.
Keep implements the NIP-55 Android Signer protocol and NIP-46 remote signing, so any compatible Nostr client can request signatures directly.
Features:
- FROST threshold signing (2-of-3, 3-of-5, etc.)
- NIP-55 Android Signer protocol
- NIP-46 remote signing (bunker service)
- Import and export FROST shares via QR code or text
- Multiple account support
- Per-app signing permissions and policies
- Biometric and PIN authentication
- Hardware-backed key storage (Android Keystore)
- NIP-44 encryption and decryption
- SOCKS proxy support (Tor)
- Encrypted backup and restore

新版本 1.1.9
Signing history entries can no longer be recorded with a time earlier than the entry before them, so a clock correction or a changed device clock cannot make one approval appear to precede another. Restoring a backup now keeps each share's recorded backed-up state instead of marking everything backed up, so the reminder to back up a share still appears when it should.
新版本 1.1.8
Adds first-run onboarding: guidance on FROST key shares and a sign-policy choice during setup. Also brings the app listing screenshots. No other functional changes.
