zkSNACKs Ltd. is a privacy-focused Bitcoin company founded in 2018 and registered in Gibraltar. The company is the developer of Wasabi Wallet, an open-source, non-custodial Bitcoin desktop wallet designed to provide strong financial privacy through built-in CoinJoin transaction mixing.

Wasabi Wallet gained prominence as one of the most effective tools for Bitcoin privacy, implementing the WabiSabi CoinJoin protocol (an evolution of the original ZeroLink framework). The wallet automatically coordinates CoinJoin rounds among users, breaking the on-chain link between transaction inputs and outputs to improve fungibility. Wasabi Wallet has been used to mix billions of dollars worth of Bitcoin since its launch.

In 2024, zkSNACKs announced it would shut down its CoinJoin coordination service, citing increasing regulatory pressure and the company's unwillingness to implement transaction censorship or blacklisting of certain UTXOs. The company had previously begun filtering certain inputs from CoinJoin rounds in 2022 under regulatory guidance, a move that was controversial in the Bitcoin privacy community. Following the shutdown of the centralized coordinator, community-run alternatives emerged using the open-source WabiSabi protocol, and Wasabi Wallet itself remains available as a standard Bitcoin wallet.
