my @primal wallet hasn't received a single zap since july 9th. i get zapped but the money never comes in. nothing but problems since the 'upgrade' to spark. it used to be one of my favorites. now it's slow, bloated, and broken. i'm literally just losing money at this point. what a disaster. it makes me so sad to have lost such a reliable wallet.

launching my second app today: zeile. it's another simple one. you pair with one person. send a note or a doodle, and it lands on their home screen via widget. 100% free. iphone only. no accounts, no user ids. just a code generated at setup. one of you shares it, the other types it in, and you approve. it's simple and there are others like it. but this one is free. nothing behind a paywall. plus i put a little extra care into the ui. had a lot of fun building and testing it. check it out:

wrote about how we've been building at numo over the last few months. we've been slinging hats behind counters, handing a pos to restaurants, putting devices in bartenders' hands, and watching what breaks. almost every change we've shipped came from these sessions.

Numo: Lessons From Standing Behind the Counter

For the last couple of months, we've been doing something we don't usually get to do: standing behind counters. Conferences, restaurants, actual me...

codex 5.6 sol is much better at identifying and laser targeting sources of jank, like split-second screen flickers between animation transition states and stuff like that.

bip110 is sedevacantism for bitcoiners.

you must respect the work. you should put in a lot of effort to show you respect the work. if you don’t take the time to do so why should other people take the time to use your product?

cleaning up recent transactions history on cashu me. old version on the left, new version on the right.

cashu tap to pay now supports jacobin conjecture counterexamples.

did a big sweep of cashu me tonight. found a lot of inconsistencies between ios and android on bolt12 and on chain. spent the day fine tooth combing to get parity between the two. onchain is also closer to parity between ios and android. android wasn't querying the block explorer from the onchain receive. now both poll every 30s and both ask the mint if the quote is paid. try it here:

the cliche 'never judge a book by it's cover' is true. this was exhilarating.

cashu me is now native on ios and android. lots of screen time went into this one and I had a blast building it. today, the public beta is here. still a lot of work to do. life time of polish to apply and jank to fix, but perfection is the enemy of good.

weekend project: cypherpunkbooks.com one shelf for books, manifestos, essays, etc... built it for myself to keep everything I want to read and everything i love in one place.

i'm being one shotted by yanis varoufakis' technofeudalism. i can feel the dunning kruger setting in.

really enjoyed this from matt balez. a few things stuck: i learned subcent api fees via usdc on base is easy. a few weeks ago in vegas i highlighted this a unique value prop for bitcoin agentic payments. i was wrong. still true that stablecoins are inherently censorable, and freezable at any time. they don't optimize for human freedom. stablecoin privacy is very spooky. the fact that you can feed an agent's etherscan history to chatgpt and id the merchant should scare everyone. "open source AI deserves open source money" is a banger. how do we meme this into existence? watching steinberger go anti "crypto" was rough. surprised usdt on lightning wasn't covered. i know usdc has the regulatory momentum rn but @speedwallet 's wallet's usdt/lightning ux is quite good. they address the volatility and short term usd obligation point all on the ln network. we can have a convo about the tradeoffs re censorship resistance, but i think bitcoin builders can learn a lot from speed.

The Best Money For Agents

Spiral PM Mat Balez weighs the relative merits of stablecoins vs bitcoin for agentic payments and nudges us towards the more neutral option.

spoke at vegas a few weeks ago on lightning and ecash. @Shinobi moderated, @EVAN KALOUDIS and Alex held it down on @ZEUS and @Fedi . fun one. thanks for having me.

thanks @SoapMiner

russian satirists have mastered the art of writing around the censor. they do it while being funny too. that's what artists are for.
