Terms of Service Agreement

Last updated: January 29, 2024

Welcome. You agree and understand that by accessing or using the Houdini Swap LLC’s (“xBlock”) website, you are agreeing to enter into this terms of service agreement, and any terms and conditions hereunder, which includes the xBlock Privacy Policy, incorporated herein by reference, which governs the terms of service by and between you and Houdiniswap, and to be legally bound by its terms and conditions. (“Agreement”)

xBlock own and operates this website, https://www.xblock.tech, other websites we own (collectively, the “Sites”), transactional services we facilitate, other products, functionality, and staking services, offered on or through our online services that link to this Agreement (collectively, the “Services”). Please note that there may be specific terms or conditions in this Agreement applicable to you as a user in a given jurisdiction, as detailed herein. Your use of our Services is subject to you complying with and agreeing to the terms and conditions set out herein in their entirety.

Use of the words “we”, “us” or “our” herein refers to xBlock. “You”, “your” and “user” refers to any individual who accesses the Services. If you access the Services on behalf of a company or other legal entity, you represent and warrant that you have the authority to bind that entity to this Agreement and, in that case, “you”, “your” or “user” will refer to that entity.

By accessing the Services, or by acknowledging your agreement to this Agreement, you agree that you have read, understood, comply with and agree to this Agreement. You further agree that the defined terms used in this Agreement, if defined in the Privacy Notice, shall have the meanings set forth herein. In the circumstance where any of the Services are subject to additional terms or agreements to this Agreement, in the event of conflict, the provisions of the additional terms or agreements shall prevail.

Please read this Agreement carefully. Feel free to print and keep a copy but please understand that we reserve the right to change any of the terms and conditions at any time. The latest version of this Agreement, 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 this Agreement your access or use of the Services shall constitute your agreement to the amended Agreement, and you agree to be legally bound by its terms and conditions as amended. You should, therefore, read this Agreement from time to time. In the event that you do not agree with any such amended terms and conditions, your sole and exclusive remedy is to cease your use of the Services.



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”). Transactions occur on a blockchain, which is a distributed ledger with growing lists of records, known as blocks, that are securely linked together via cryptographic hashes (collectively “Blockchain”). In order for a Transaction to complete it must be confirmed and recorded on its associated Blockchain. Blockchains are decentralized, peer-to-peer networks supported by independent third parties, which we do not own, control, or operate. By accessing the Service, you acknowledge and agree that any Transaction may not be completed, or may be substantially delayed.

The Services do not store, transfer, transmit, convert, broker, hold, escrow, mint, mine, or otherwise interact with any Digital Assets, security, financial instruments, or other digital or physical assets. The performance of all Transactions occurs on third-party platforms and are subject to their associated third-party terms.


We strongly encourage you to review any order details carefully when accessing the Services.

Staking Service

When you hold a Digital Asset in your wallet you may choose to access, via the Services, the xBlock staking service which allows you to lock or “stake” your Digital Assets on the Blockchain for a period of time with the intention of in return earning additional Digital Assets, or “staking rewards” (“Staking Service”). Please note staked Ditial Assets are not subject to the protections of the Federal Deposit Insurance Corporation (FDIC), the Securities Investor Protection Corporation (SPIC), the UK Financial Ombudsman Services, the European Securities and Markets Authority (ESMA) or any other similar protections.

xBlock earns fees by way of a referral commission for the facilitation of Transactions, which is paid by third-party providers. Each third-party provider independently determines what fees it charges in its function for the provision of the Transaction, as well as the commission fees earned by Houdini Swa. A majority of these fees support the Staking Service. The proportion of fees allocated to the Staking Service are defined in the Staking Program.

During your participation with the Staking Service your staked Digital Assets will be restricted from transfer or sale (“Staked”). If when using the Staking Service you nominate to unstake your Digital Assets, you will not have access to your Digital Assets until the expiration of any applicable notice or waiting period (“Notice Period”), unless you choose to accept an early unstake penalty fee being, the payment of which is offset against the balance of your staking account. The penalty fee is defined in the Staking Program. You will not earn rewards on the balance of your staked assets during the Notice Period.

You have no right to a staking reward until it is delivered by the Staking Service to the Blockchain smart contract which solely manages the distribution of Staking Service rewards to staking participants.


You agree and understand that by accessing or using our appl;ication programming interface (API), software development kit (SDK) or inline frame (iFrame) you are agreeing to the terms herein. If any term or condition of this Agreement is unacceptable to you, you must not use these Services.

Third-Party Services

We engage with third-party providers, such as cryptocurrency exchanges, who provide products and services, and which may include the use of third-party APIs, over which we have no direct or indirect control (“Third-Party Service”). Third-Party Services are governed by their respective terms and conditions. Such terms and conditions may include separate fees and charges, as well as disclaimers or risk warnings on the accuracy of the information or the services they individually provide which may include a privacy policy that differs from our Privacy Notice. You should read and understand the terms and conditions of Third-Party Services, including how they may collect and use your personal information. The respective terms and conditions of Third-Party Services also govern other matters, including but not limited to their eligible use requirements, restrictions on certain localities, Prohibited Users hereunder, or any other eligibility-related terms. As a result, your access to certain aspects of the Services may be restricted by those third-party providers.


You hereby acknowledge that Third-Party Services are the sole responsibility of the third-party providers providing them. You hereby expressly release us from any liability arising from the use of any Third-Party Service, third-party website, or content and any resulting harm, loss, or damage.

Dispute Resolution

You and xBlock agree and understand that any controversy, claim, or dispute arising out of or relating to this Agreement or the Services – past, present, or future – shall be settled solely and exclusively by binding arbitration. Arbitration is to be held in England, or another mutually agreeable location, including remotely by way of video conference. A mediator may be appointed by mutual agreement, or else by the Centre for Effective Dispute Resolution (CEDR) and conducted in English.

You and xBlock expressly agree that any dispute about the scope of this Agreement to arbitrate and/or the arbitrability of any particular dispute shall be resolved in arbitration in accordance with this section. You and xBlock expressly agree that an arbitrator may issue all appropriate declaratory and injunctive relief necessary to ensure the arbitration of disputes (but only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party’s individual claim).

You and xBlock agree that the arbitrator shall have the authority to order any remedies, legal or equitable, which a party could obtain from a court of competent jurisdiction in an individual case based on the claims asserted, and nothing more. The arbitrator shall not award punitive or exemplary damages to either party, unless such remedies would otherwise be available under applicable law. You and xBlock agree to keep any arbitration strictly confidential.

You and xBlock agree to act in good-faith, informal efforts to resolve any disputes. A party who intends to seek arbitration must first send to the other a written Notice of Dispute (“Dispute Notice”). Any Dispute Notice to xBlock must be sent to ops@houdiniswap.com (“Notice Address”). Any Dispute Notice to you by xBlock will be sent to the email address, or social media profile, made available to us through your accessing the Services. Any Dispute Notice must include: (a) the name, address, and email address of the party providing the Dispute Notice; (b) a description of the nature and basis of the claim or dispute; (c) an explanation of the specific relief sought and the basis for this relief. Any Dispute Notice from you must be individualized, meaning it can only concern your dispute and no other person’s dispute. Any Dispute Notice from xBlock must be individualized, meaning it can only concern you and no other person. You also agree that, after sending a Demand Notice to xBlock, at our request you will personally participate in a discussion by telephone, or via an agreed third-party platform such as Telegram, with us to discuss whether an agreement can be reached to resolve the claim before arbitration is initiated. We also agree to participate in such a telephone discussion at your request. Any informal dispute resolution conferences shall be individualized, such that a separate conference must be held each time either party intends to commence individual arbitration; multiple individuals initiating claims cannot participate in the same informal telephonic dispute resolution conference, unless mutually agreed to by the parties. You agree that compliance with these informal dispute resolution procedures is a condition precedent to commencing arbitration, and that the arbitrator shall dismiss any arbitration filed without fully and completely complying with these informal dispute resolution procedures.

If you and xBlock do not reach an agreement to resolve a claim within 60 days after a Demand Notice is received, you or xBlock may commence an arbitration proceeding; except that, if either you or xBlock send the other an incomplete Dispute Notice, the 60-day period begins only after a complete Dispute Notice is received, and if either you or xBlock request a telephone discussion, the 60-day period begins only after the discussion has occurred. Any statute of limitations and any filing fee deadlines shall be tolled while the parties engage in these informal dispute resolution procedures.

Should any dispute proceed to arbitration, you and xBlock agree that; (i) the arbitration shall be conducted by one neutral arbitrator; (ii) each side agrees to bear its own legal fees, costs, and expenses, unless such remedies would otherwise be available under applicable law, or unless the arbitrator finds that a claim, counterclaim, or defense is frivolous or brought for an improper purpose; and, (iii) all pleadings submitted in arbitration are subject to sanctions being imposed where the arbitrator finds the pleadings are submitted for an improper purpose, such as to harass, cause unnecessary delay, or needlessly increase the cost of litigation. The arbitrator may issue orders (including subpoenas to third-parties, to the extent permitted by law) allowing the parties to conduct discovery sufficient to allow each party to prepare that party's claims and/or defenses, taking into consideration that arbitration is designed to be a speedy and efficient method for resolving disputes. You and xBlock agree to abide by all decisions and awards rendered in such proceedings and you and xBlock agree that such decisions and awards rendered by the arbitrator shall be final and conclusive.

To the extent you or xBlock seek emergency relief in connection with any controversy, claim, or dispute arising out of or relating to this Agreement or the breach thereof, or your relationship with xBlock, you and xBlock agree that the this Agreement restricts you or xBlock from seeking emergency relief from any court, including without limitation temporary restraining orders and/or preliminary injunctions, and you and xBlock agree that, to the extent either party breaches this Agreement by seeking such relief from a court, that party shall be responsible for paying the opposing party’s legal fees in opposing such relief, and the arbitrator shall render an award of such legal fees at the earliest possible time after such fees are incurred. You and xBlock agree that you or xBlock may, without inconsistency with this arbitration provision, apply to any competent court hereunder for an order enforcing the arbitral award. You and xBlock irrevocably and unconditionally agree to waive any objection that you or xBlock may now or hereafter have to the laying of a venue of any action or proceeding relating to enforcement of the arbitral award in the courts of England.

In arbitration the parties waive their rights to have a jury trial. If for any reason this arbitration section becomes not applicable or for any other reason litigation proceeds in court then you and xBlock agree; (i) to the fullest extent permitted by applicable laws and regulations, hereby irrevocably waive all right to trial by jury as to any issue relating hereto in any action, proceeding, or counterclaim arising out hereof, or any other matter involving us hereto; and, (ii) submit to the exclusive jurisdiction and venue of the relevant courts located in England and you agree not to institute any such action or proceeding in any other court in any other jurisdiction.

You and xBlock agree to arbitrate solely on an individual basis, and agree and understand that this Agreement does not permit a class action or private attorney general litigation or arbitration of any claims brought as a plaintiff or class member in any class or representative arbitration proceeding or litigation (“Class Action Waiver”). The arbitral or other tribunal may not consolidate more than one claimant’s claims and may not otherwise preside over any form of a representative or class proceeding. Nothing in this paragraph shall be construed to prohibit settlements on a class-wide or representative basis. If any portion of this arbitration clause is held to be invalid or unenforceable, the remaining portions will nevertheless remain in force. In any case in which (i) the dispute is filed as a class or representative action and (ii) there is a final judicial determination that all or part of the Class Action Waiver is unenforceable, the class and/or representative action to that extent must be litigated in a civil court of competent jurisdiction, but the portion of the Class Action Waiver that is enforceable shall be enforced in arbitration. Additionally, if a court determines that a public injunctive relief claim may proceed notwithstanding the Class Action Waiver, and that determination is not reversed on appeal, then the public injunctive relief claim will be decided by a court after any individual claims are arbitrated, and the parties will ask the court to stay the public injunctive relief claim until the other claims have been finally concluded in arbitration.

Even if you and xBlock have entered into any other agreement, this dispute resolution section shall govern the resolution of any and all disputes arising from or related to the relationship between you and xBlock. You agree that this section herein has been included to rapidly and inexpensively resolve any disputes with respect to the matters described herein, and that this section shall be grounds for stay or dismissal of any court action commenced by you with respect to a dispute arising out of such matters. A printed version of this Agreement shall be admissible in judicial or administrative proceedings.



You agree that if any provision herein, or application thereof, shall be determined to be invalid or unenforceable under any rule, law, or regulation or by any governmental agency, local, state, or federal, such provision will be changed and interpreted to accomplish the objectives of the provision to the greatest extent possible under any applicable law. You further agree that the validity of or enforceability of any other provision (or of such provision, to the extent its application is not invalid or unenforceable) of this Agreement shall not be affected.

Change of Control

In the event that we are acquired by or merged with a third-party entity, we reserve the right, in any of these circumstances, to transfer or assign the information we have collected from you as part of such merger, acquisition, sale, or other change of control.


You agree that all provisions herein, which by their nature extend beyond the termination or expiration hereof, including, but not limited to, sections pertaining to suspension, investigations, remedies for breach, termination, debts owed, right to offset, unclaimed funds, general use of the Services, disputes with us, and general provisions, shall survive the termination or expiration hereof.


Section headings herein are for convenience only, and do not govern the meaning or interpretation of any provision hereof. Unless the express context otherwise requires: (i) the words “hereof,” “herein,” “hereunder” “hereto” and words of similar import, when used herein, shall refer to this Agreement as a whole and not to any particular provision; (ii) the terms defined in the singular have a comparable meaning when used in the plural and vice versa; (iii) wherever the word “include,” “includes” or “including” is used herein, it shall be deemed to be followed by the words “without limitation”; (iv) the word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply “if”; and (v) the word “or” shall not be interpreted to be exclusive.

English Language Controls

Notwithstanding any other provision herein, any translation of this Agreement is provided for your convenience. The meanings of terms, conditions, and representations herein are subject to their definitions and interpretations in the English language.


This Agreement, or your rights and obligations hereunder, may not be transferred by you, but may be assigned by us without restriction. Any attempted transfer or assignment by you in violation hereof shall be null and void. This Agreement shall be binding and inure to the benefit of the parties hereto, our successors, and permitted assigns.

Governing Law

This Agreement, your use of the Services, your rights and obligations, and all actions contemplated by, arising out of or related to herein shall be governed by the laws of England, as if this Agreement is a contract wholly entered into and wholly performed within England.

Entire Agreement

This Agreement comprises the entire understanding and agreement entered into by and between you and xBlock as to the subject matter hereof, and supersedes any and all prior discussions, agreements, and understandings of any kind (including without limitation any prior versions of this Agreement), as well as every nature between and among you and us.
