There are reports that users installing Minibits on Android from Github and Zapstore are not getting over-the-air wallet updates. I therefore released a new cumulative update of current native version including all OTA updates as an APK package to Github and Zapstore, tagged v0.3.4-beta.19. Please check the version you are running in Settings > Developer options: 👉 if you still run old release 0.3.2-beta.x, please update immediately, there were important bugfixes released over time in 0.3.4. This is valid for all users, including those that use Google Play. 👉 if you run 0.3.4-beta.8 or beta.11 and you are not offered OTA update in Settings > Update manager, please check Github or Zapstore and upgrade to the new version ✌️ if you run 0.3.4-beta.19, you are running the best Minibits out there. Enjoy!

Happy to share that @Minibits has been selected for continued grant support from @OpenSats 🎉 Grateful for the trust and excited to keep pushing open-source ecash R&D for #Bitcoin forward!

Minibits now adds support for NFC payments on iOS 🚀 Wallets on iPhones can receive ecash or read and pay payment requests over NFC from wallets running on android devices. Simplicity of #cashu ecash in action. https://github.com/user-attachments/assets/448c9ca9-6863-47e6-a598-f5628ba9df32

With the New year, Minibits mint rotated to the new keyset with id starting 001... For most wallets, handling keyset change should be automatic and should not cause any issues. Former keyset, with id starting 005... is now not active, but stays available for ecash swaps or melts - that allows wallets to rotate to the new one over time seamlessly. In case you'd need to recover some ecash generated with previous keyset, make sure to set the keyset id to recover from to the previous 005... value as well (if using Minibits wallet) Reason for this change is to be able to handle the database growth: there is more then 2.5m of issued ecash notes and 2.2m of spent ones, that the mint needs to keep to prevent double spend. For now, I've implemented mutiple database optimizations to keep it performing + have realtime backups in place, but to be able to reduce the db size in the future, I'll rotate to new keysets at least once per year. Enjoy the winter as I do!

New Minibits with Tap-to-pay is live on Android! - Reads a cashu requests or lightning invoices via NFC and pays instantly - Shares invoices or cashu tokens (emulating NFC host) so you can even tap two Minibits wallets Prototype intended for testing w POS devices, that have their NFC antennas on front side but nevertheless very funny to play with 🚀 ! Very early, test with few sats only. https://github.com/user-attachments/assets/d52700af-469b-42d7-a35b-1e11e043ef3f

I’ve been rethinking how Contacts work in Minibits. First step: Public Contacts now let you search Nostr users by name or address — and see their follower count to avoid fakes.

Minibits is now on the iOS App Store! The new 0.3.2-beta release is out for both Android and iOS. It fixes several reported issues and makes wallet recovery simpler. What I didn’t expect was to pass the full App Store review on the first try — no questions asked! From now on, you can enjoy Minibits on iOS without TestFlight. 🚀
