something i'm really proud of with numo:
paying feels exactly like apple pay. press one button on your iphone, tap, beep, done.
perfectly private. bitcoin as everyday money.

2026-02-18 00:46:37 CET

primal following notifications have become totally unusable. everyday i’m followed by like 50 bots.

getting a bunch of primal notifications.

2026-02-15 10:49:42 CET

anyone else getting a flood of followers lately? open claw bots working overtime.

tease the design slowly! release little clips and screenshots. i want to see what @npub1t3g…upxq is cooking!

looks ugly imo

2026-01-26 19:21:31 CET

been vibing a cashu wallet in swift. the friction i want gone: having to pick ecash or lightning at the time of send or receive.
i'm experimenting with a mode selector on the top right. exploring whether treating it as a mode toggle instead of an inline choice feels better. https://blossom.primal.net/be9e5e1fc5ba8f6ba226c74b421755f90e3e478589bef0028d0e752b51e53f88.mp4

do you think a man can vibecode better than god?

During @nprofile…py4c Dev/Hack/Day I gave a talk on the State of Cashu Design. I'm sharing the presentation here along with a few key points.
https://blossom.primal.net/6117f56a511d20f482ff56641fbbbd867147a3c5915428b63b3a057815396014.png
I covered 3 common problem areas that Cashu applications face, what wallets are currently doing to address them, what we could be doing better and how Multinut Payments helps address some of these points.
https://blossom.primal.net/ef8bb65ad4aa088773311a09ec5b07369c2dd8ae19ed2909d1f71215b00fb44f.png
Discoverability & Onboarding
One of the most common hurdles users experience when they first download a Cashu wallet is the "How do I find a mint?" question.
https://blossom.primal.net/1608297d3047553b2a6321b25bb6aeb23905b4a21128babf0011d0d2a4f69a40.png
Some wallets that have made progress in addressing this. Cashu.me and @nprofile…4r7c They have a built in a mint discovery feature, the data is pulled from bitcoinmints.com. Cashu.me does a great job of keeping the discovery flow in wallet.
https://blossom.primal.net/e96d5951f877bb6e2b01614a6f4c388fcf62c001345208d2d0ddf3c78d8964bd.mp4
What could we be doing better?
Bitcoin Mints is a great resource but the current mint list display still requires significant cognitive effort on the users behalf.
Here's a design idea that could reduce that cognitive bottleneck.
Note: There is a centralization risks associated with this design. By showing a limited number of highly rated mints we could be reducing the variety of mints people are using across the Cashu ecosystem.
https://blossom.primal.net/2655a79800310ff182ebf77b7e7e64051fdca6d897cf3342746fe72a2aa06f60.png
Rug Protection & Risk Mitigation
Another common problem users face is knowing the risks associated with a mint.
How can users make a more informed decision when picking a mint? bitcoinmints.com shows community ratings (e.g. 4.2⭐) for each mint, but is that enough?
https://blossom.primal.net/3434d92a3dc2eb15792f8b6220252b5ebd84fd676fda46cb520cbcc8654b2d44.png
We can combine a mint auditor https://audit.8333.space and mint swaps to increase rug protection and reduce risk.
Let's talk about the mint auditor. It provides detailed information about the performance, uptime, and reliability of Cashu mints.
Cashu.me and @nprofile…0a8l have integrated the mint auditor. In Cashu.me the user can see the mint audit information in a modal before they decide to trust a mint.
https://blossom.primal.net/7fda6bb247f1bc9b8e14dca82654a1fc79233891334f3e5b646a23632d5648d3.mp4
What could we be doing better?
Combine the community reviews from bitcoinmints and the audit data from a mint auditor. This could make it easier show the user the most important info in plain english.
https://blossom.primal.net/2498789ac60b1106ea95ed564c395eda4c3a3c41d3bba7d0c389be0a6bb3dbda.png
Next up, Mint swaps.
Mint swaps allow users to receive ecash into their trusted mint. Reducing the need to hold ecash from unknown mints. Cashu.me and Macadamia https://macadamia.cash both support mint swaps.
https://blossom.primal.net/d2590b304abeb1658f125c0a1499b8ec7902c1774b6f6932e51c61562b79cd70.mp4
Lastly, I want to talk about Multinut Payments. A feature I am very fond of and I think will play a huge role in risk mitigation in the future.
https://blossom.primal.net/6a881028826a7468bb3f23020aa20c82461d21e1aaeac0d90b658884ea920ab0.png
Multinut payments is still in the very early stages. http://Cashu.me is the only GUI wallet that supports it as of right now.
When making a LN payment for an amount larger than your current mint balance, Multinut Payments allow the user to pay using the balance from multiple mints.
https://blossom.primal.net/dc53789b9408c4de987f7b5b60e60deb49a26a444d9c684bbc0fd640cc9c4224.mp4
As bullish as I am on Multinut Payments, I know that the UX (right now) is not where it needs to be. If I told you that executing a Multinut payment is simple, you would be right to call me a liar.
https://blossom.primal.net/97818f6fe38ccf15f8d3fc6a9be427f64da2270fb14a0f1ab13e5d3cd5d6d874.png
The current user cognitive costs outweigh the benefits. Users have to manually choose mints, decide how much to send from each, and manage multiple balances. It feels like doing accounting or using an abacus just to pay an invoice.
https://blossom.primal.net/27c4bdf0587f17cbc608018b6ab605cec5cffae30aeb9be7b93ba1287e6d6e42.png
What the user actually wants is simple: Pay while being able to spread risk across mints, without losing the convenience of ecash.
I think this Steve Jobs quote nails where we are. The groundwork is here, but we haven’t had enough time to design it so it feels like magic.
https://blossom.primal.net/50c82ebbdf713e84c0460135493804dee0cddfdeb196fc47c90f7a79fa410e54.png
The goal isn’t to make users feel smart. It’s to make them feel like it was easy all along.
We have to make it simple. The more time and energy we spend, the better the tools will be.
https://blossom.primal.net/58e428813d7f2f619e0ae4634e26b0ed8779049cb1746d6155d2aa5846769eb6.png
YOU can help us. You don't need to be a developer or a designer. One of the biggest ways to help is to just USE the tools and give us your thoughts. Tells us what you found confusing, what words didn't make sense. What you felt could be better. Your feedback is a gift.
