Wasabi provides network level privacyOther light wallets sacrifice your privacy in exchange for speed by leaking all of the addresses in your wallet to a third party server. This third party server also is able to see the IP address your wallet connects from, which can provide them even more data to tie your Bitcoin addresses to your identity.
We live in an Orwellian surveillance society where your information is being used to typecast and manipulate you. Bitcoin projects are being pressured to collect more and more data, if possible. This is why Wasabi Wallet is programmed to be a zero-knowledge software. Developers can't collect any sensitive information about you. What you do with your Bitcoin is your business.
Wasabi innovates on the light wallet design and solves these privacy leaks by masking your wallet addresses with
client side block filters, and masking your IP address with
Tor. Although combining these two technologies this reduces the privacy footprint for receivers to a single address, the addresses are still visible on a public ledger, so another step must be taken to hide the origin of the coins you received from the destination you send them to, and vice versa. This traceability is broken by
coinjoins.=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Wasabi provides blockchain level privacyWabiSabi research paper (Ádám Ficsór, Yuval Kogman, Lucas Ontivero, and István András Seres): https://eprint.iacr.org/2021/206.pdfWasabi's most impressive privacy feature is the ability to participate in coinjoin transactions. A coinjoin combines your coins non custodially into a bulk transaction with other users in order to make your Bitcoins untraceable. The outputs of a coinjoin can't be tracked to the inputs because the outputs created have identical clones with the *exact* same value. Even the coinjoin coordinator themselves cannot determine which inputs and outputs belong to each participant:
The whole WabiSabi protocol is a really complex beast which involves a lot of cryptography from Pedersen commitments, zk-proofs, balance proofs, range proofs, ownership proofs, a strobe construction around Keccak and others that play together to create the credentials system. The protocol involves the construction of http messages that have to be sent to the central coordinator in a randomized schedule under different Tor identities to guarantee the unlinkability of the participants' transactions against the central coordinator.
Here's an example of a Coinjoin transaction on mainnet with 400 inputs and 407 outputs:

There is a cost tradeoff for using the optional coinjoin feature. Participating in a coinjoin transaction will
always cost a miner transaction fee, and may cost a one-time 0.3% coordinator fee, depending on the value and origin of the input you are registering. The following inputs do not pay any coordinator fees:
- Any inputs with a value of 1 million sats (0.01 BTC) or lower
- Any outputs from a coinjoin that you remix for additional privacy
- Any change from spending inputs that were already coinjoined
- Any coins sent to you by other Wasabi Wallet users that were already coinjoined

Cold storage interfaceWasabi also allows you to connect your USB hardware wallet such as
BitBox02, Coldcard, Jade, Ledger, or
Trezor.=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Reputation for innovationWasabi Wallet was awarded a share of Bitcointalk's longstanding coinjoin development bounty, along with JoinMarket:
Congratulations to the Wasabi and JoinMarket developers! JoinMarket pioneered a lot of CoinJoin science (and BTW, belcher wrote an excellent & comprehensive wiki article on privacy), while Wasabi is the first wallet that implements CoinJoin in both a highly-usable and sound way. As both a signer and a donor to the CoinJoin bounty fund, I'm thrilled that these two pieces of software exist!
For everyone looking to improve their privacy, I highly recommend checking out Wasabi, especially over centralized "mixers".
