summary: FROST threshold signer and Nostr event signer for Android
description: |
  **Keep is a FROST (Flexible Round-Optimized Schnorr Threshold Signatures) threshold signing app and dedicated Nostr event signer for Android.**

  It allows users to hold FROST key shares on their 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.

  Keep keeps private key material segregated from client apps through NIP-55 and NIP-46, with per-app permissions, background signing, and multiple account support. It splits keys into FROST threshold shares (2-of-3, 3-of-5, etc.) so that no single device ever holds the complete private key.

  **Features:**

  - FROST threshold signing (2-of-3, 3-of-5, etc.)
  - NIP-55 Android Signer protocol (intents + content provider)
  - NIP-46 remote signing (bunker service)
