The wallet and the company are not the same thing
Wasabi Wallet is MIT-licensed software. zkSNACKs was the company that built it and ran the coordination service it used by default. Keeping the two apart is the whole point of this entry, because one of them stopped and the other did not.
Where it came from
Wasabi's own documentation traces the work back further than the product: "Ádám Ficsór worked with several others on a privacy-focused Bitcoin wallet called Hidden Wallet all the way back in December 2015." Wasabi 1.0 was unveiled by him at the Building on Bitcoin conference in 2018, released as beta on 1 August and in full on 31 October that year.
What it built
A coinjoin is one transaction with many participants, built so an outside observer cannot say which output belongs to which input. Wasabi's second-generation protocol, WabiSabi, runs it in five phases: input registration, connection confirmation, output registration, signing, and a blame round that restarts if someone drops out. The coordinator collects signatures, and the docs state it "cannot steal funds or link inputs to outputs", because the participant registering inputs and the one registering outputs reach it over separate Tor connections.
Legal history, on the record
The developer discontinued the default coordinator. The removal commit in the project's own repository shows the notice the client displayed to users: "The default coinjoin coordination service provided by zkSNACKs is discontinued as of June 1st 2024. To continue using the coinjoin feature, enter a new coordinator in the Bitcoin Settings." The documentation records the same date. The wallet kept working for sending and receiving, and the site now tells users to find a third-party coordination service provider. The copyright line in the repository moved too: it read "zkSNACKs" through 2023 and now reads "The Wasabi Wallet Developers".
The discontinuation happened against a wider enforcement climate around coinjoin coordination in the United States, which the project's own removal notice reflects. This entry does not detail prosecutions of other organisations: the individuals in those cases are not part of this directory, and naming people facing criminal charges on the entry for a different project is not something a source we could open would support.
zkSNACKs' own incorporation could not be established from a primary source, which is why structure here reads Undocumented. Listing is not endorsement.
