1/ Payjoin boards have been available in Bark for a couple of weeks now, so we thought it was time to take a closer look at what they can do: boarding direct from external wallet apps, saving the user fees and time, and the same trick applied to on-ramping into Cashu mints.

Would any of you like to do a live review of the @stablechannels Android app on a call with me? I’d love to watch you use it, hear what’s confusing, and problem-solve together. Decentralization + great UX are hard. Let’s figure it out together 🤝

2026 Q2 Update: What Have We Been Up To? bdk_wallet 3.1.0, bindings 3.0.0 (brand new libraries! bdk-rn + bdk-dart), and more! bitcoindevkit.org/blog/2026_…

Entirely accidental but I think Enclavia is falling into place as "right thing at the right time". Bitcoin companies need all the security they can get and we are getting ready to offer it

A big thanks to this years @summerofbitcoin students Rishit and Domenec. Some great work was done and FOSS skills learned. domenec-madrid.github.io/blo… blog.summerofbitcoin.org/fro…

Big milestone for me: the first stable Android release of Stable Channels is now available. If you think bitcoin users deserve a better way to manage volatility—without stablecoins—give it a go and share your feedback.

What happened to the developers from the first Bitcoin Dev Launchpad cohort? More than a year later, many are now working full-time on Bitcoin open source, supported by grants or engineering roles across the ecosystem. A quick look at where they are today 🧵

In this episode of 🎙️Bitshala Bitcoin Talks🎙️we sit with @codingp110 to explore her journey. From a college student discovering Bitcoin, to becoming a Bitshala Fellow contributing to @bitcoindevkit.🚀 Falling down the Bitcoin rabbit hole is just the beginning. A conversation about going deeper, beyond the surface, and into the technology that makes Bitcoin possible.🎧📽️⏬

"I took one of my trading partners to the mat. We were all high-fiving on the trading floor. Three months later he set up a whole business that destroyed everyone's." Chase Koch on why zero-sum thinking is a losing strategy.

A high level overview of how funding works in bitcoin open-source.

Nick Johnson's goal was to "become a rust-bitcoin contributor or maintainer." He is now a rust-bitcoin maintainer working on stabilizing the crates that half of bitcoin's Rust ecosystem sits on. His job is to make sure nothing interesting ever happens to these crates again.

Four DKs, one grantee. The seal is broken. @thesimplekid is helping build Cashu Dev Kit (CDK), a Rust SDK for building Cashu wallets and mints without implementing the protocol yourself. Elsewhere on the roadmap: onchain support via BDK, payjoin via PDK, unified balances via LDK.

Rust engineers needed, DM me if interested! Forming a group now

.@weikeng is building Private Information Retrieval (PIR) for bitcoin: query the UTXO set without revealing what addresses you are interested in. It’s a rare way to gaze into the bitcoin abyss without it gazing back.

Since we stopped working on @TwentyTwoHW Portal due to commercial difficulties I've always wanted to turn it into a fully open and community-led project. This might be a good time to kickstart the effort. If anybody wants to pick it up I'm happy to ship dev boards to you!

Bitcoin Red Team Update: We have been working around the clock, with ~$20,000 of spend up to this point across different services. Funding is secured, I appreciate all the gestures for donations but it is not necessary. The bill is taken care of. We have done over a dozen disclosures up to this point, with 150 repos scanned. The hardest part is coordinating to get things to the right people (thank you @danielabrozzoni for the help) I have a first pass on a bitcoin red team agent harness which only requires an @opencode zen api key, makes it easy for us to use K3 for the actual heavy lifting and then GPT Sol + Fable/Opus + GLM5.2 for supporting documentation. While it is powerful, having found critical issues, I would view this as only version one. There is a lot of iteration I'm looking forward to improving on. Our goal is to open source the harness so it can be pointed at internal repositories for insights so the hardening of defenses can go deeper than the code which is made public. We also have been connected with OpenAi for some help so I could manage getting the @OpenAI Cyber Harness running as well (thank you @lylepratt ). Its a much more expensive scan, but well worth it for load bearing portions of the bitcoin ecosystem and has already yielded good results. Goals for tomorrow are scale in processes and systems so we can do a better job and automating full end to end functionality to get humans out of the loop for the heavy lifting. The first mile (requests/staging) and last mile (handoff of reports) are the choke points right now. Thank you @stutxo @callebtc @benthecarman @thesimplekid and so may more.

🚨 X Live | Wednesday, 6:00 PM BST TOMORROW: we will be talking to @afilini on X Spaces about the devastating Coldcard Attacks with a live Q&A Help session for anybody that needs it. Get your questions ready!

Over $250B of value sits in stablecoins instead of Bitcoin. Stable Channels is built to change that. This demo 👇 features the @stablechannels server and iOS app, powered by splicing, just-in-time channels, and new server tech from @lightningdevkit, @bitcoindevkit & @spiral_xyz
