WHO THIS HELPS

My project helps people who need on-chain privacy for their bitcoin, and a secure way to participate in collaborative transactions (a.k.a. coinjoins / private payments).

WHAT YOUR SUPPORT MAKES POSSIBLE

You will help fund LLM tokens to debug / red-team / review PR's for Wasabi Wallet, this is an ongoing 218€+/month expense. Also any future upgrades to the coinjoin.nl server, it now runs on a Raspberry Pi5 with an NVMe SSD. Also the domain name registration costs of 16,50€/year.

Last year in 2025 the official Wasabi Wallet coordinator (zkSNACKs company) has been sunset due to legal pressure and the scare following the arrest and imprisonment of the 'competitor' Samourai Wallet developers Keonne & Bill. As a user of Wasabi Wallet I had been closely following this problem and had been experimenting with running my one 'one-click' install coordinator in the BTCPayServer plugin that existed at that time. Since then I've helped test new features in the Wasabi Wallet's coordinator and I switched to running the coordinator on a dedicated Raspberry Pi5 without the BTCPayServer plugin (it was no longer actively maintained). My focus was on making cheaper coinjoin rounds possible, which I was able to write and merge so that 0.5 sat/vB transactions are the norm now. After this I started with the hardware wallet coinjoin signing project, which now is released as Wasabi Preview (pre-releases) from my own git and signed by my PGP key. The goal is to have this feature release in the next large Wasabi 3.0 update, where we focus on making a super secure software architecture that can't be powned by the army of hostile AI agents that attack anything and everything on the internet nowadays. I will help the project with automated AI reviews of all PR's, active project-loupe scanning of the codebase and dependencies and help writing the hardware wallet signing portion of Wasabi Wallet. 
All of this to be able to host the weekly coinjoin.nl Sunday's where we come online together to do a collaborative transaction that helps preserve our on-chain privacy. As a coinjoin will protect your forward spending privacy, by breaking the deterministic link between your inputs and outputs of the collaborative transaction. Instead you now hide in a crowd of Noderunners for anyone analysing the blockchain.
