Tap to pay with Bitcoin View quoted note →

I dont really understand it but sounds very cool and promising :) View quoted note →

Congrats 👏🎉

Open-source ecash team shipped tap-to-pay while the 'crypto payments' industry is still filling out compliance paperwork. Permissionless infrastructure just keeps quietly lapping the licensed version.

I've just downloaded it, and MAAAAN the UX is impeccable. Big kudos. One small note about mints management. I think there should be a ⭐ rating next to each mint, to help users search and choose their mints. These ratings should use WoT (default is global, but can configured with a target npub) to filter out scams, impersonators and so on. I've been thinking about ecash mint reputation in @Vertex for a while, maybe I should give it a go what do you think?

Oh wow, sexiest cashu product I've seen by far 👀 Except for the mints UX indeed. Similar issues to relays. Why am I seeing random shady looking urls on the second screen? Should probably be pubkeys with mint profile metadata imo. Can do way cooler stuff with that.

The entire space needed this. Congratulations on the build. #Open_source_the_world Put out privacy and security behind the key.

Cool ! IOS release ?

Very nice app, runs smooth and is easy to understand, even for no coiners.

This is rad.

Love those nuts 💋

I gave Numo a quick try, and I could get to tap-to-pay in a few seconds! Strong concept, great execution! I've found some issues, listing them constructively in a reply below.

Quick Numo test observations Installation: - From ZapStore/Graphene: ✅ - minor: None of the APKs from Github worked on an older Android device 🤷‍♂️ (prob. due to being older, should be fixed with PlayStore inclusion) Onboarding: - super fast ✅ LN pay with QR: - worked right away, no glitch ✅ (used Blink) NFC: - had to enable and remove the covers of the phones, standard NFC stuff 🤷‍♂️ Tap pay: - used Minibits (I needed a quick install Cashu wallet on regular Android, I chose Minibits). Had to find out how to activate NFC payment on Minibits with the small NFC-like icon - Tap-to-pay worked! ✅🚀 - Sometimes the tap took several seconds, not really tap-boom-done but tap-hold-hold-done 😟 I think this is when the payer wallet does mint operations for proper denominations DURING the nfc exchange process. Very error-prone. Offline tap pay: - First tests failed 😟 Reason is no right denominations - With amount round in sats (100 sats) it worked ✅ General UI: - Balance is not showed. The only place I could find it is during withdraw. Withdrwal: - Worked fine (I used cashu withdraw to cashu.me) Others: - The POS-selected Cashu/LN setting is not nice UX, it would be better if the payer can decide on this somehow. The user-controlled Cashu/LN is prone to huge user confusion. - Peyer wallets should optimized for denominations that cover all amounts. This setting should be the default (vs. size optimizaed). In case of error, it should show the closest (largest) possible denomination, maybe that's fine to use (overpay by few sats). - After a failed cashu payment, Numo reverts to LN. This can get unnoticed and get confusing. - There was one instance when the payer wallet claimed success, but Numo showed error. I was not able to recover the sent ecash on the payer side (proofs already spent), so my guess is that it actually succeeded, but Numo showed it as error. Dangerous, as it may be lost funds. - For withdraw cashu a QR option would be nice.

fyi^^^ @a1denvalu3 @calle
