Wasabi

Wasabi is a non-custodial, open-source Bitcoin wallet focused on privacy. Its core business is providing a desktop client that integrates CoinJoin, a trustless multi-party transaction protocol, to break the on-chain linkability of Bitcoin transactions. The wallet also routes all traffic through the built-in Tor network and uses BIP-158 compact block filters for client-side scanning, so the server never learns which addresses a user controls. Hardware wallet support (ColdCard, Trezor, Ledger, BitBox02, Blockstream Jade) is included via HWI.

The core narrative is "your keys, your privacy": the code is fully auditable on GitHub, and the wallet has never suffered a user fund loss in its seven-year history. The main pain point it solves is Bitcoin's default public ledger, where transaction history can be traced by surveillance companies. CoinJoin breaks these heuristics by merging multiple users' inputs into equal-amount outputs with a large anonymity set.

In the past six months (2026-02-28 to 2026-08-29), the project has focused on transitioning away from its own CoinJoin coordinator, which was shut down in June 2024 due to regulatory pressure. Users now connect to third-party coordinators listed in the app (e.g., opencoordinator.org, coinjoin.swisscoordinator.com). The wallet also added support for sending to Silent Payment addresses, introduced a P2P-based block filter download to eliminate reliance on a single server, and improved fee control with RBF support. A notable negative event: in July 2024, a security disclosure described L7 DDoS attacks on free coordinators and a malicious coordinator abusing fee parameters, both patched in v2.1.0 without compromising clients. Additionally, the operator's 2022 decision to filter UTXOs based on Chainalysis blacklists and the 2024 exclusion of US users from its own coordinator remain controversial, though they did not affect user keys or funds.
