37 weeks ago, I started working on Coco: a TypeScript framework and developer kit for building Cashu wallets and applications. The goal was simple: make Cashu app development in TypeScript as easy, modular, and reliable as possible. Coco provides a storage-agnostic core for wallet logic, proof management, mint sync, quote handling, subscriptions, operation recovery, and typed events, plus maintained adapters for Node, Bun, IndexedDB, and Expo/React Native. It also includes React hooks for building wallet UIs on top of the same core primitives. Today, after roughly 120,000 lines of code written in over 600 commits, and 55 alpha releases, I am very proud to announce that Coco v1 is now stable and available on npm under the @cashu scope. This release marks the first stable foundation for developers who want to build Cashu apps in TypeScript without rebuilding the same wallet infrastructure from scratch. But the work has just begun! Coco already takes care of the typical Cashu operations, but v2 is already being laid out. Custom units, more methods and other amazing improvements are going to land very soon (tm). Github:

Just wasted an hour trying to correctly record Bitcoin income in my bookkeeping software… Without success Germany’s bureaucracy really knows how to turn simple things into a full-time job 🤦‍♂️ No wonder entrepreneurs are leaving

Batch minting is coming to the Cashu protocol, and I can not wait to supercharge npub.cash with it!

It has been 4 days since I decided to let my personal AI assistant OpenClaw take control of my fitness. Here is how this is working out for me:

After a decade out of shape, I set a goal: lose 10 kg and cut my 5K time from 31:00 to 24:30. Instead of hiring a coach, I built one. Meet Coach Claw: my personal trainer built on OpenClaw. Will it work? I don't know, but i'll keep you posted.

Beeeeep! 🤙 Bitcoin tap-to-pay is live. Numo turns your smartphone into a next-gen Bitcoin POS. Massive congrats to the whole team, this is HUGE 🙏🥳

This is going to be SO MUCH fun! 🦀 👀

People don't yet understand what a massive change OpenClaw means.. For testing purposes I just ordered a BitBox hardware wallet. - My agent did the checkout by itself (needed my address, since it's not in USER.md). - My agent paid for the order using Lightning and it's own integrated Cashu wallet (cocod skill)

Be a good human and give your agent a way to transact:
