Bitcoin is not private
Bitcoin transactions are publicly visible to anyone. That’s great to prevent inflation and fraud without relying on third parties. But it has some privacy drawbacks.
Coins in the Bitcoin network are called UTXOs (Unspent Transaction Outputs). Each coin has a unique transaction history and is accounted for by every full nodes. So all Bitcoin transactions are easily trackable at all times.
reclaim your privacy
Privacy by default
Get started with privacy by default. All traffic is routed via Tor by default. Your wallet is synchronized using client-side block filters. Gain on-chain privacy with the built-in coinjoins.
Enjoy optional insights and control with hardware wallets, custom privacy profiles, coin control, privacy warnings, change avoidance, personal full node, developer tools and more.

Why Wasabi Wallet
Download
OPEN SOURCE
Wasabi Wallet is a free and open-source software. Anyone can see, verify and even contribute to the code.
STRONG PRIVACY
Neither the public nor developers can breach your privacy. Use of coinjoins, block filters and the Tor anonymity network guarantee that.
SELF-CUSTODIAL
Not your keys, not your bitcoin. You're in full control of your private keys.
SIMPLE
With Wasabi Wallet good privacy on bitcoin just works. Use a simple yet functional wallet with all the features you'd expect.
ACCESSIBLE
Coinjoin with any amount, from 5,000 sats to 40,000 BTC and anything in between. WabiSabi is the coinjoin protocol under the hood that makes it work.
AFFORDABLE
WabiSabi is a next generation coinjoin protocol, designed with blockspace efficiency as a priority so you save on mining fees.
A coinjoin is...
A collaborative bitcoin transaction. In a coinjoin, many different users coordinate the creation of one single transaction with inputs and outputs from different users.
A coinjoin transaction has many standard outputs of the same amounts, which makes it very hard to track them back to their initial inputs.
Coinjoins allow users to conceal the history of their coins from the public to make their UTXOs fungible on the public Bitcoin network.

Mining fees and coordinator fees
When coinjoining, you always pay the mining fees for the block space you use. Then coordinators can also charge a fee for their service. Both are configurable to avoid overpaying.
FAQ
A coinjoin is a collaborative transaction between multiple peers.
Usually, but not necessarily, it consists of some standard output denominations that participants should break their coins in to. This makes it difficult for outside parties to trace where a particular coin was sent to (as opposed to regular bitcoin transactions, where there is usually one sender and one receiver).
Coinjoins can be done with non-custodial software like Wasabi Wallet, that eliminates the risk of funds disappearing or being stolen. The funds will always be in a bitcoin address that the user controls and not even the coordinator can alter the transaction or redirect the funds.
Coinjoin basically means: “when you want to make a transaction, find someone else who also wants to make a transaction and make a joint transaction together”.
No, Wasabi’s coinjoin implementation is trustless by design. The participants do not need to trust each other or the coordinator. Since only the user knows the private keys, only he can sign the transaction, which will only be done after verifying that everything is alright. Nobody can neither steal your coins, nor figure out which outputs belong to which inputs.
Wasabi does support hardware wallet usage through the standard Bitcoin-core HWI, and coinjoining straight to a hardware wallet is possible, but signing a coinjoin trasaction with a hardware wallet is not implemented.
Here's a list of the officially supported hardware wallets.
No. Wasabi’s features, like Tor and coinjoin, require considerable computational power, which are currently not replicable on a smartphone.
There are countless reasons why it is the only logical choice to be bitcoin-only. With Bitcoin we have a once in a lifetime opportunity to manifest libre sound money. If we succeed, then an utmost beautiful agora of sovereign individuals may emerge. If we fail, then this will conjure up the most horrific Orwellian nightmare. There is no room for wasted time and energy, this great work requires our full attention. Any line of code written to support a random shitcoin takes away scarce developer time to work on real problems.
Wasabi Wallet runs in most operating systems with 64-bit and arm64 architecture, like Linux, MacOs and Windows. Wasabi Wallet does not required a lot of storage, CPU and Memory, it should run on basically any hardware. For the complete list of all the officially supported operating systems, click here.
All Wasabi network traffic goes via Tor by default -there's no need to set up Tor by yourself. If you do already have Tor, and it is running, then Wasabi will try to use that first.
You can turn off Tor in the Settings. Note that in this case you are still private, except when you coinjoin and when you broadcast a transaction. In the first case, the coordinator would know the links between your inputs and outputs based on your IP address. In the second case, if you happen to broadcast a transaction of yours to a full node that is spying on you, it will know the link between your transaction and your IP address.
Addresses being used more than once is very damaging to privacy because that links together more blockchain transactions with proof that they were created by the same entity. The most private and secure way to use bitcoin is to give a brand new address to each person who pays you. After an address has received a coin, it should never be used again. Also, a brand new bitcoin address should be demanded from the recipient when sending bitcoin. Wasabi has a user interface which discourages address reuse by removing from the GUI addresses which have received a coin.
It has been argued that the phrase "bitcoin address" was a bad name for this object because it implies it can be reused like an email address. A better name would be something like "bitcoin invoice".
Bitcoin isn't anonymous but pseudonymous, and the pseudonyms are bitcoin addresses. Avoiding address reuse is like throwing away a pseudonym after it has been used.
The passphrase you set is used as a 13th seed word (as described in BIP 39) and to encrypt the private key of the extended private key (as described in BIP 38) to get an encrypted secret which is stored on the computer.
Wasabi Wallet stores only the BIP38 encrypted blob, so you'll need to type in the passphrase to spend or coinjoin from the wallet.
The passphrase will unlock your bitcoin to anyone who has access to the recovery words backup or the computer! If your backup gets compromised, this password is the only thing protecting your precious sats.
It is important to use a random and long passphrase.
