Amber
Amber is a nostr event signer for Android. It allows users to keep their nsec segregated in a single, dedicated app. The goal of Amber is to have your smartphone act as a NIP-46 signing device without any need for servers or additional hardware. "Private keys should be exposed to as few systems as possible as each system adds to the attack surface," as the rationale of said NIP states. In addition to native apps, Amber aims to support all current nostr web applications without requiring any extensions or web servers.
What's new in 6.6.9
- Redesigned Multi-Request Screen: Requests are now grouped by application, displaying each app's name, icon, and request count, along with per-app support for the "remember my choice" option.
- Automatic Clipboard Clearing: Copied sensitive data (such as nsec, ncryptsec, or seed words) is now automatically cleared from the clipboard after 60 seconds, even if Amber is closed or running in the background.
- Key Safety Fix: Resolved a critical issue that could cause the loss of your nsec or seed words when toggling the "require unlocked device" setting.
- Immediate Permission Enforcement: Revoked permissions now take effect immediately without needing to clear the app cache, and reject rules are properly applied even for fully trusted apps.
- nostrconnect:// Fixes: Fixed an issue where connection requests approved from the multi-request screen failed to receive a response, ensuring replies are correctly sent via relays defined in the URI.
