# Wasabi wallet | Bitcoin privacy wallet with built - Wasabi
Wasabi Wallet is a privacy-focused Bitcoin wallet designed to enhance the anonymity and fungibility of Bitcoin transactions. Launched in 2018, Wasabi Wallet employs innovative techniques to break the linkability of transactions, providing users with a higher level of privacy and security in their cryptocurrency transactions.
#### Privacy Features:
**1. CoinJoin Implementation:** Wasabi Wallet utilizes a privacy technique known as CoinJoin, which allows multiple users to combine their Bitcoin transactions into a single transaction. This makes it challenging for external observers to trace individual transactions back to specific users. CoinJoin enhances the fungibility of Bitcoin by mixing coins from different sources, making it harder to identify the origin of a particular coin.
**2. Chaumian CoinJoin:** The wallet implements a variation of CoinJoin called Chaumian CoinJoin, named after the cryptographer David Chaum. This method ensures that the anonymity set—the group of participants in a CoinJoin transaction—is effectively utilized, providing stronger privacy guarantees.
**3. Confidential Transactions:** Wasabi Wallet integrates Confidential Transactions, a cryptographic technique that encrypts the transaction amount, making it private and unlinkable. This feature adds an extra layer of confidentiality to Bitcoin transactions.
**4. Coin Control:** Users have the ability to manually select which UTXOs (Unspent Transaction Outputs) they want to include in a transaction. This gives them more control over the privacy of their transactions by choosing specific coins with different origins and values.
#### User Experience:
**1. User-Friendly Interface:** Wasabi Wallet is designed with a user-friendly interface, making it accessible to both beginners and experienced users. The wallet's layout is intuitive, and it provides a smooth experience for managing Bitcoin transactions.
**2. Open Source:** Wasabi Wallet is an open-source project, allowing users to verify the code for security and transparency. The open nature of the project fosters community collaboration and helps build trust among users concerned about the security of their funds.
**3. Compatibility:** Wasabi Wallet is compatible with major operating systems, including Windows, macOS, and Linux, making it accessible to a broad range of users.
#### Security Measures:
**1. Full Node Integration:** Wasabi Wallet connects to a Bitcoin full node, which enhances security by allowing users to validate their transactions and avoid reliance on external servers. This also contributes to the overall decentralization of the Bitcoin network.
**2. Tor Integration:** The wallet supports Tor (The Onion Router) for enhanced privacy. By routing transactions through the Tor network, Wasabi Wallet helps obfuscate the user's IP address, making it more difficult for third parties to trace transactions back to specific individuals.
**3. BIP 158 Support:** Wasabi Wallet supports BIP 158 (Block Filter Index) for improved privacy. This feature allows users to filter blocks for specific transaction data without downloading the entire blockchain, reducing the amount of information exchanged with the network.
#### Conclusion:
Wasabi Wallet is a significant step forward in enhancing the privacy and fungibility of Bitcoin transactions. By incorporating advanced privacy features like CoinJoin, Confidential Transactions, and offering a user-friendly interface, Wasabi Wallet empowers users to transact in Bitcoin with greater anonymity and security. Its commitment to open-source principles, integration with full nodes, and support for Tor further solidify its position as a privacy-centric Bitcoin wallet in an era where privacy is a growing concern for cryptocurrency users.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://wasabiiwalletti.gitbook.io/usa/wasabi-wallet-or-bitcoin-privacy-wallet-with-built-wasabi.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
