Cashu95 #ecashdesign

I am not ready for what is coming. View quoted note →

I have a huge urge to become a UI Engineer. I'm tried of just designing in Figma. I want to ship code.

Starting intermittent fasting. Not doing a bunch of research or anything, I’m just drinking coffee and eating only between 5am and 12am. Day one down. Will share periodic updates.

My talk from from Bitcoin Asia is now up. I discussed designing for ecash, showing examples of what bitcoin backed ecash can do that Lightning can’t, and share some examples of what ecash products are doing well.

Been diving into how DNS changes impact ecash. Took a look at Fedimint and Cashu’s approaches and possible solutions. Would love your thoughts on it.

#5 On ecash DNS & Configuration Issues.

UX considerations for ecash mints that lose access to their DNS and require configuration updates. What are some current and future solutions?

I had fun working on this design at the ecash hackday. Teamed up with @Dario to create a concept for sending ecash notes via Bluetooth on Macadamia. Can’t wait to refine and ship this. iOS users, check out Macadamia. It’s a beautiful Cashu wallet:

macadamia Wallet for iOS

Please, no more Bitcoin merch with a giant orange ₿. We look ridiculous walking around with that. We have the best designed electronic cash protocol in history but the worst merch imaginable.

What kind of information do you look for when choosing an ecash mint? When you look at the list on

Bitcoin Mints

what do you find helpful? What is missing?

Been digging into Cashu mints a little deeper lately and got a much better grip on how they're set up. Mints let operators customize some meta data fields. This got me thinking about how these fields can be used in the UI to show important info to users. I used the bitcoin.design community UI kit to whip up quick concept of how a mint might display these fields to users. I'm really excited about the potential use cases for the MINT_INFO_MOTD (Message of the Day) field. If mint operators use this for urgent messages, apps could show this as an in-line alert. This could be really helpful for sharing important updates like downtime or future shutdowns. Including an action button in the alert is probably not realistic, but would be a nice touch. Some people have thrown out an idea of a mint that automatically rugs after certain amount of time. Alerts could be really useful here. If a wallet detects a MOTD, it could display it on launch or send a push notification. Gotta think about the risks and potential misuse too.

Laid the foundations for an eNuts design system on Figma. The design system is a fork of the Material 3 Design System. Once published, this will make it easy for anyone to contribute design ideas.

Really wishing I had a space like @PUBKEY. Would be amazing to drop in on a weekend like this for the camaraderie.

@Deleted Account @OpenSecret getting an unknown error when I try to join a federation. Could it because I haven’t added any stats to my wallet?

Finding a way to convey multisig output descriptors so they're easy to digest and a great user experience is a nightmare. This is the trenches of Bitcoin UX design, for real.

Spent the weekend exploring designs for showing stable assets like USD, EUR on Cashu. A challenging edge case: when users have different assets within a mint, and also spread across different mints. Cross-mint interoperability for stable assets makes my mind melt.

This is one of the best talks on ecash on bitcoin. Start here if you’re curious to learn more. So much was covered. View quoted note →

Finally got to jam on some new eNuts designs. I'll be dialing back on sharing concepts here until the dev team gives them a look. I love publicly exploring, but I'd rather not tease UIs that might not make it. You can still have a peek on github though: https://github.com/cashubtc/eNuts/issues/309#issuecomment-2000734721

Exploring some enhancements for the @eNuts ⚡️🌰 send flow. My current focus is on unifying the processes for sending lightning and ecash. I believe that eliminating the need for users to choose between ecash or lightning before reaching the send screen is an improvement. What do you think?
