Max Hillebrand, CEO of zkSNACKs, stated that it was necessary to shut down CoinJoin services due to the lack of clarity in US regulations on the use of cryptocurrency and privacy-enhancing tools. Hillebrand also confirmed that the Bitcoin wallet, Wasabi Wallet, which includes CoinJoin services developed by zkSNACKs, will continue to operate as a regular BTC wallet. Users can generate private keys to receive and send Bitcoin. Despite the closure of CoinJoin services, Hillebrand stated that Wasabi's client-side filtering architecture, Tor integration, and custom coin selection still provide important privacy features for users.
