Wasabi is an easy to use, privacy-focused, open-source and non-custodial Bitcoin wallet.

NOTE: Wasabi Wallet sends all coinjoin input transactions to a chain surveillance partner and blacklists all bitcoin tied to 'criminals.'

"We’ve packed Wasabi Wallet version 2.0.4 with highly requested features and a bundle of performance optimizations that drastically speeds up wallet load time, frees transactions from getting stuck in the mempool and make life easier than ever for privacy-conscious Bitcoiners."
"Key upgrades include transaction speedup with RBF and CPFP, privacy warnings when sending transactions, and a headless daemon for advanced users who prefer using their keyboard instead of their mouse. Tasks running in the background now take even less time with improvements made to coinjoin output efficiency and wallet synchronization speed."

“Since the last release four months ago, the amount of progress is mind-blowing. Now Wasabi is even faster, more private, and easier to use. The contributors have really outdone themselves this time,” said Max Hillebrand, CEO at zkSNACKs and Contributor to Wasabi Wallet.

What's new

Turbosync drastically reduces wallet load times. "This release optimizes the filter checking process to reduce wallet loading times by 90% thanks to code cleanup and a clever key prioritization process dubbed 'Turbosync.'"
Speed up unconfirmed transactions. "Incoming funds can now be confirmed faster with Child Pays For Parent (CPFP) to self-spend an unconfirmed UTXO, and outgoing transactions can use Replace By Fee (RBF) to increase confirmation priority or cancel the payment entirely."
Privacy warnings and spending suggestion. "New Privacy Warnings present users with one click fixes if they are attempting to construct a transaction that spends nonprivate funds or creates change."
Cheaper coinjoins especially for whales. "The amount decomposer was refined to make the most effective use of scarce block space so that whales who set a high anonymity score target now need fewer coinjoin rounds to reach 100% privacy."
Headless daemon and improved RPC interface. "Wasabi now has a daemon! More experienced users can directly interact with core features of the wallet through an RPC (Remote Procedure Call) interface making it easy for developers to customize their experience and build features that are not available in the GUI version."
QR code scanning for Linux to copy payment addresses. "Wasabi can now scan QR codes on Linux computers. This feature is now available for Linux and Windows, but not yet for macOS."
Database migration to SQLite. "Wallet loading speed improved even more by storing the filters in an SQLite database instead of a plaintext file, reducing disk space requirements by about 1 GB and increasing resilience against file corruption."
Improved Tor behavior.
Hardware Wallet Interface updated to v2.2.1.
Decoupling of the user interface for better testing and alternate client support.
Separation of WabiSabi cryptography library for compatibility with other projects.
Sunset of Wasabi Wallet 1.0 zerolink coinjoin coordination.
