Cordn Coordinator

Android
Android

The open-source Cordn MLS delivery coordinator as an Android app. Runs as a
foreground service: publishes your coordinator's Nostr identity (npub /
nprofile + QR), stores MLS key packages, welcomes, join requests, and opaque
group message streams in app-private storage, and streams messages to group
members over Nostr relays.

  • MLS key-package publishing with last-resort support
  • Welcomes and join-request delivery
  • Per-group ordered message streams (backlog replay + live tail)
  • Stable Nostr identity encrypted by the Android Keystore
  • SQLite storage in the no-backup directory; erase or reset from the UI
