▪️Privacy Notice

Welcome to xBlock!

Last Updated: January 29, 2024

Welcome! xBlock's approach to data collection is carefully calibrated to balance your privacy, effective customer support and our obligations to third-party providers.

This Privacy Notice explains how Houdini Swap LLC. (“xBlock”) collects, uses, discloses, and otherwise processes user information in connection with our website, https://www.xblock.tech, and other websites we own and operate, including but not limited to transactional services we facilitate, other products, functionality, and staking services offered on or through our online services (collectively, the “Services”) that link to this Privacy Notice (“Privacy Notice”).

Use of the words “we”, “us” or “our” herein refers to xBlock. “You”, “your” and “user” refers to any individual who accesses the Services.

By accessing the Services, or by acknowledging agreement to either the Terms of Service Agreement (”Agreement”) or Privacy Notice, you confirm that you have read, understood and agree to the Privacy Notice governing the Services in its entirety. You further agree that the defined terms used in the Privacy Notice, if defined in the Agreement, shall have the meanings set forth herein.

Please read the Privacy Notice carefully. Feel free to print and keep a copy of the Privacy Notice, but please understand that we reserve the right to change any of these terms and conditions at any time. The latest version of the Privacy Notice, with its date of update, can be always found on this page.

You agree and understand that by accessing or using the Services following any change to the Privacy Notice your access or use of the Services shall constitute your agreement to the amended Privacy Notice. You should, therefore, read the Privacy Notice from time to time.


This Privacy Notice does not address practices relating to xBlock personnel.

Transaction Data

A transactional related event accessed by the Services, such as a “swap”, “send” or “cross-chain swap”, requires the use of cryptocurrency, digital tokens or digital assets (“Digital Assets”) (collectively “Transaction”). When you use our Services for Transactions, we automatically collect data, which includes the sending wallet address, the receiving wallet address, types and quantity of token sent and types and quantity of token received and internet protocol (IP) address (“Transaction Data”). We do not engage in activity which may cause us to personally identify you. However, whilever we retain Transaction Data we do maintain personal information which may give us the ability to do so.


Doing so allows our customer support team to have sufficient information to address user queries or issues effectively. In instances where a customer support matter extends beyond the standard 72 hour retention window, we retain the relevant Transaction Data until the issue is fully resolved. Post-resolution, this Transaction Data is promptly deleted using our platform’s automated deletion processes.

User Data Deletion

Recognising the importance of user autonomy, we offer users the option to immediately delete their Transaction Data from our platform database when transacting. This option, available on the Working Our Magic Page, empowers users to control their data privacy.

You should be aware that opting for immediate deletion of Transaction Data may impact the complexity and effectiveness of resolving potential support issues. Please consider this trade-off when selecting this option.

Law Enforcement

In cases where law enforcement authorities request information within the 72 hour retention window as part of their investigation into illicit activities, xBlock will cooperate to the extent permitted by law.

Our Collection of Personal Information

In addition, and separately to, Transaction Data, we collect other types of personal information in connection with your accessing the Services. This collection includes information that you provide in connection with the Services as well as information from third-parties.

Personal Information Collected from Individuals

We may collect the following personal information submitted to us by individuals through the Services:

Staking Service Data

Please be aware that by virtue of the public nature of blockchain networks, the Houdini Swap Staking Service (“Staking Service”) account and transactions associated with your wallet address will be available to us. Information stored on the blockchain may not be able to be modified or deleted due to its immutable nature.


Please consider how privacy and transparency on the blockchain works. The details of our private transactions can be found here.

Account Information

To use our Staking Service you are required to establish an account. This involves collecting the public blockchain address associated with your crypto wallet. We may also collect your usernames, Houdini ID and password for using our Staking Service and Services. We use this information to administer your account, provide you with the relevant services and information, communicate with you regarding your account, the Services, and for customer support purposes.

Crypto Wallets

In participating in our Staking Service, when you connect your crypto wallet we receive information such as your wallet address. We do not engage in activity which may result in us accessing additional information in your crypto wallet but you should be aware that in accessing your wallet address we have the capability to do so. This includes information such as crypto wallet types (including amounts and balances), any related transaction and technical information associated with your crypto wallet address, including network information regarding transactions.

Token Information

If you choose to participate in our Staking Service, we may receive certain token transaction and event-related information, including your public blockchain address associated with your self-hosted crypto wallet used in the Staking Service, the amount of your staked balance, and Staking Service event-related information such as dates, time and quantity of transfers of Digital Assets.
