Wasabi Wallet is an open-source, non-custodial desktop bitcoin wallet oriented to privacy. It implements hierarchical deterministic wallets, address-reuse avoidance, mandatory coin labelling, BIP158 client-side block filters, Tor transport, and historically the WabiSabi protocol for centrally coordinated CoinJoin transactions. The project repository is maintained publicly on GitHub.

Features

Wasabi supports creating, recovering, and hardware-connected wallets; coin control and labelling; Opt-in PayJoin; dust-attack protections; and optional connection to a local or remote Bitcoin full node (including Bitcoin Knots) for rule enforcement. Documentation lists supported BIPs and installation paths for Linux, Windows, and macOS, including PGP signature and deterministic-build verification.

CoinJoin and WabiSabi

Wasabi 1.x used a ZeroLink-style chaumian coinjoin design. Wasabi 2.0 introduced WabiSabi, an anonymous-credential scheme for centrally coordinated coinjoins with more flexible amounts. While the default zkSNACKs coordinator was live, that company coordinated rounds and charged a coordinator fee on fresh inputs above a stated threshold, with remix paths historically treated differently in the fee schedule. The coordinator design aims to prevent the coordinator from spending user funds; privacy properties depend on the protocol and user behaviour and can be reviewed in the open-source code.

Historical fee schedule while the zkSNACKs coordinator was operating:

	Above 0.01 BTC	0.01 BTC and less
Fresh input	0.3% coordination fee + mining fees	mining fees
Remix (including a 1-hop transaction)	mining fees	mining fees

zkSNACKs coordinator suspension (1 June 2024)

On 2 May 2024, coverage of a zkSNACKs announcement reported that the company would suspend its coinjoin coordination service effective 1 June 2024. zkSNACKs stated that Wasabi Wallet would continue as a regular bitcoin wallet: users can still generate keys and send and receive bitcoin, and client-side filtering, Tor integration, and coin selection remain. The company said it would fund continuous maintenance of Wasabi’s basic features. Other clients that pointed at that coordinator (for example Trezor Suite and BTCPay Server paths) were affected per that coverage. Third-party or community coordinators may exist separately from the suspended zkSNACKs endpoint.

Controversies

On 13 March 2022, reporting described plans for the zkSNACKs coordinator to blacklist certain tainted coins from coinjoins. Parts of the bitcoin community criticised the approach. Wasabi / zkSNACKs stated they did not have access linking user identities and that the blacklist step was proactive rather than required by a cited statute in those reports. Those accounts describe a community controversy and operator policy choice rather than a criminal conviction.
