Read full descriptionHide full description
Igloo is a mobile companion for Frostr threshold signing on Nostr. With Igloo, your iPhone can operate as a signing node in a threshold group. The app focuses on clear onboarding, signer visibility, and day-to-day operational safety. Key features: - Import credentials using QR scan or manual entry - Run your phone as a threshold signer node - View peers and check connectivity - Monitor signing sessions and logs - Use Demo Mode to explore the app without production credentials - Store credentials on-device with platform secure storage Important notes: - Igloo responds to valid threshold signing requests from your peer quorum. - Igloo does not independently initiate signatures. - iOS uses a background audio/soundscape mechanism to keep signer processing active when the app is backgrounded.
