Thanks for spreading the support @MaelstromFund

This is the first grassroots, novel Payjoin cut-through implementation using PDK that we've seen. Huge.

Big thanks to @btrustteam for the support to work on Payjoin Really appreciate @payjoindevkit team for their support and guidance . Shoutout to @btrust_builders @BitDevsKaduna @FreeRoutingAf your programs and community played a huge role in getting me here Keep building 🚀

Wallet fingerprints are subtle and can undo the hard work you do to preserve your privacy. Broke this down in my latest post.

This would be a massive boon for on-chain privacy. Making every lightning channel re-balance transaction a PayJoin transaction would begin to erode the efficacy of common input ownership heuristics used by chain surveillance companies.

Excited that PayJoin is working towards integrating into lightning opens & splices. Would be awesome if we got that! Wanted to clear up my earlier tweet about this (attached). It is something they're going to do. Lots of complex issues to solve to get there but lets go!

Okay I spoke with Dan and this is something they're working towards. It appears they've written PayJoin into LDK for the onchain wallet, with the intention of eventually getting it integrated into channel opens & splices. That would be super exciting if they can get there 🚀

Why isn't Payjoin the standard? @BullBitcoin_ can't be the only ones

Payjoin Dev Kit continues to ship. This week we released our C# bindings!

Payjoin Foundation receives 501(c)(3) status to fund bitcoin privacy The @payjoindevkit announced its designation as a 501(c)(3) non-profit status from the Internal Revenue Service, effective July 23, 2025. The designation allows the organization to accept tax-deductible charitable contributions to fund open-source privacy protocols. The foundation maintains a dedicated budget to recruit talent directly for deep technical work. This strategy bypasses the delays of external grant processes the organization termed “Bitcoin Grant Purgatory.” "Having an organized foundation with a dedicated budget enables us to recruit talent to solve specific problems rather than recommend an external org make a grant to each individual contributor," Payjoin lead maintainer @bitgould said in the foundation blog post.

It’s not every day that we post “good news” from the IRS. But today, the Payjoin Foundation has been recognized as a 501c3 – which means you can now make tax deductible donations to fund Bitcoin privacy. By @joakimbook👇
