I think maintainers need to find better ways to filter out bad slop from good slop instead of blocking slop contributions altogether. If AI writing and reviews work hand-in-hand we can build an FOSS flywheel

We’re back in business and getting together for our weekly Cashu TypeScript dev call today at 11:00 UTC (in about 70 minutes).
Today’s call will be a review of the recent releases, as well as a quick planning and brainstorming session for the next versions of cashu-ts and coco. Meeting link: https://meet.fulmo.org/CashuTsDevs

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).

- My agent paid for the order using Lightning and it's own integrated Cashu wallet (cocod skill)

Yes, probably. But that would have taken a lot more coordination with the old dev that worked on that site years ago (getting access etc).

Developers that don’t get up-to-speed on AI and automation quickly are going to have a bad time very soon.
I dear friend of mine has an ancient typo3 website (~2,500 pages) that was in desperate need to a migration. He asked me for help
I spawned a new OpenClaw on a VPS with my default config, told it to create a local Strapi CMS, crawl the url of the old site and scrape all the content into the new strapi system. Once that is done, it should create a modern NextJs project in the look and feel of the old website and wire everything up.
It took TWO hours. The new site is live, faster, and most importantly no longer threatened by an ancient MySQL and php version.

Not everyone has the same threat model. For most people it should be perfectly fine sharing all calendar details. And it is managing my calendar, but with this architecture I can control exactly what it sees.
Sensitive events go into the protected calendar, non sensitive ones in the unprotected. That way it can schedule, know what availability looks like and keep me up to date.

What about it? It's a spectrum. My Claw runs in an isolated VPS with a firewall that allows only Tailnet traffic. The calendar I gave it access to is a proxy that does not have any event details, but only blockers. That way it is able to schedule for me without knowing anything about my schedule but blocks.
I have not found a good solution for email yet. I am thinking to have a separate instance running emails through my homelab that runs local models, but I have not gotten to that yet.

2026-02-03 09:23:37 CET

It would be an additional network trip, but also very likely to incur swap fees. Wallets will try to optimise their proof database to make sure the denominations don’t result in huge tokens, but sometimes it’s unavoidable. For anything else there are animated QRs, which are pretty standard in Cashu enabled wallets

2026-02-03 06:32:08 CET

- reply

That’s what every Cashu wallet does. If the proofs in store don’t fit the required amount the wallet will do a swap first. Only in offline environments wallets will tolerate an overspend if instructed by the user

Want to harden your openclaw deployment?
0) Disable password based ssh
1) Install Tailscale and set it up (preferably with your own Headscale)
2) Configure Caddy to proxy your nodes tailnet IP to the openclaw web UI (only required if you need the Web UI)
3) Test by ssh-ing on the tailnet ip and accessing the Web UI
4) Diable ALL ingress traffic in your VPS firewall expect for UDP 41641
5) Test again by ssh-ing on the public ip -> should fail

Headscale ships with an embedded derp server. If you are worried about public ones, use your own.

I might be wrong here, but I don’t think nebula has any benefit over Tailscale if you host it yourself using headscale

Next, throw away your proprietary, cloud-based CCTV bullshit, get some PoE IP cameras and a PoE switch, install frigate and go2rtc on your unraid box and wire everything up. Welcome to your FOSS, self-hosted and sovereign CCTV setup.

1) Buy an old mini pc / server
2) boot unraid
3) Host your own tailscale network using headscale
4) Connect your devices using your tailscale network

Wanted to see whether I was actually right about Coco and tried to build a web wallet in 30 minutes, starting with an empty dir. Adding mints, send, receive and mint quotes working :D I think I did great

On the other hand, Bevel calculates a “nutrition score” and these are the variables 🤮

It’s the very first time in 10 years that I started to log all food again and it made me feel really old.
My wife showed me hoe you can simply upload a picture of your plate to Bevel and it would produce 90% accurate macros from it.
And my first thought was: “Back in MY day, we had to scroll through endless fddb lists, 90% of barcodes were not yet in the system and prepping for competition you might have brought your scale to the restaurant

@SatsAndSports coco has a plugin API and integrated keyring for P2PK stuff. Want to jam on a Cashu channel plugin for it?

Coco (https://github.com/cashubtc/coco) is the fastest way to go from zero to a working web Cashu app. You can have a React wallet up and running in under 30 minutes, writing all code yourself.
I’m looking for brave testers to take it for a spin, find the rough edges, and tell me where it breaks. Your feedback would mean a lot.

Coco RC42 is released! This includes the new saga-based MeltOperation that I have been tinkering on for weeks, making Melts so much more transparent and safe. A summary of the new feature can be found here: https://cashubtc.github.io/coco/pages/melt-operations.html
