v0.3.0
d74a07d

Multi-identity release. Cambium remains the Android NIP-55 signer that holds no keys: every signature comes from your paired Heartwood hardware signer over NIP-46.

What's in 0.3.0

  • Multiple identities. Pair each Heartwood identity separately (each bunker URI is one identity). Apps bind to an identity when you approve them; NIP-55's current_user (npub or hex) selects the identity per request. Cambium never substitutes identities silently: a request naming an identity it does not hold is refused, and an ambiguous request asks. Each identity gets its own isolated connection, request queue and decrypt cache.
  • Activity log. An on-phone, metadata-only record of signer activity: app, method, event kind, identity, outcome. No event content, plaintext or ciphertext is ever stored. Toggle off or clear at any time.
  • App lock. An optional biometric or device-credential gate on the management screen and approval decisions. Background signing for already-approved apps is never gated.
  • Existing 0.2.x pairings and approvals migrate automatically.

Install

Requires a paired Heartwood signer (pair via Sapwood: Apps, Connect an app, scan the QR). Android 8.1+, no Google Play services.
