A few days ago, I decided to archive the #UtxoPocket repository. Also close TG group.
I won’t be able to maintain it, and even though it’s a watch-only wallet, I think these are tough times for open source.
As a developer, it’s not worth it for me, and I don’t have the capacity to take on risks such as potential issues arising from the use of the app.
It was great while it lasted. I’ll be happy to answer any questions anyone might have.
I apologize because I don’t think I handled this in the best possible way, but I felt a sense of urgency after the ColdCard disaster and everything we’re seeing these days.
There haven’t been any problems or issues—I simply don’t have the capacity.
Best regards to everyone, and many thanks to those of you who have participated in one way or another.

UtxoPocket is now available on Zapstore:
It is a privacy-first Android watch-only wallet for monitoring Bitcoin descriptors, UTXOs, labels, and wallet activity without handling seeds or private keys.
If you use it, I’d really appreciate a comment or feedback on Zapstore. Real-world usage reports, issues, suggestions, or general impressions help a lot.

UtxoPocket v0.12.0
Big privacy, recovery, and networking release.
Highlights
• Local Direct for your own node: connect to a trusted local/private Electrum node without Tor when you are on your LAN or connected through your own VPN. In tests, a wallet sync that took ~3 minutes over Tor finished in ~20 seconds through a local node.
• Calculator mode: optional launcher camouflage. Enable it in Settings → Security → Calculator mode. The app appears as Calculator; open it, enter 21000000, tap =, then unlock with your normal PIN. Disable it from the same Security setting.
• Encrypted watch-only backups: export/import .ubak backups for wallets, labels, collections, and selected app preferences. PIN, duress PIN secrets, node policy, and signing material stay out of scope.
• UTXO collections: organize outputs visually with local collections and inspect them from improved wallet detail views.
• Incoming transaction detection: placeholders are kept until canonical BDK sync reconciles them, making incoming alerts easier to follow.
• Stronger security flows: hardened duress PIN transitions, panic wipe behavior, Tor fail-closed policy, Local Direct validation, and sanitized diagnostics.
Notes
• Tor remains the default privacy boundary for public presets and onion endpoints.
• Local Direct is explicit opt-in only for infrastructure you control.
• Calculator mode is UI camouflage, not a second authentication factor.
• For the full changelog, verification details, and known issues, read the release notes.

Resuming work on UtxoPocket. I said it multiple times last months but new projects came in. Like 4 or 5 months or so without touching it.
Now with first version of NostrCity released I have a couple of weeks to work on UP.
Last night I was fixing a bug and getting ready the promised 0.12.
More news soon.
