No internet? No problem. With @Cashu you can send ecash offline for specific amounts. For fiat-denominated payments, in @Sovran we will automatically select the closest sat value that can be sent offline. This is almost always within <$0.01 of the intended amount—so small that its not meaningfully different.

Something we’re adding to this: if you send $10, the wallet will automatically try to pick a sat amount that’s spendable offline. A penny is ~15 sats right now, so we can adjust by ~±8 sats without meaningfully changing the dollar value. If that still doesn’t produce an offline-spendable amount, we can show a popup offering a wider range (usually just a couple pennies). Feels like a nice UX compromise since people sending dollars don’t care about the 8th decimal place of BTC. Thoughts? 📝 da03a0c0…

I’ve been working on a new offline send flow for @Sovran. With @Cashu, offline sends are possible, but only for specific denominations. Our approach lets users choose whether to round up or round down to the nearest valid amount, making it easier to adapt the send amount for offline use while still giving users a bit more control. I chose this approach instead of building a proof selector. In my testing, proof selection felt much more complicated for normal users. With this flow, the wallet automatically calculates the proofs needed behind the scenes.

I ran out of Opus credits, so I decided to try Cursor (Auto) instead and built an X-inspired image viewer for Nostr posts in my app, @Sovran. I do not have much experience building complex gesture animations or controls, so I am really happy with how this turned out.

I think I need to by a tablet now because this looks like fun 📝 55042bf8…

One of the hidden wins of the AI boom is that Bitcoin no longer gets blamed for the GPU and memory price increases.

Don’t send me to the front lines — I can vibe code.

I’m really proud of how far I’ve taken Sovran. I have lots of features to share over the next week or so and I’m actively building more features into the app. If you download the app and have any feedback please do share it with me. None of this would be possible without the help of @OpenSats and the upstream contributors of Cashu & Nostr! 📝 34810166… 📝 34810166…
