Terms of Service

Latest update: April 25, 2025Please read these Terms carefully and retain a copy for your records. Additional terms or conditions may apply to you depending on your jurisdiction, as outlined below. For details on how we collect, use, share, and otherwise process your personal information, please refer to our Privacy Notice.

AGREEMENT TO TERMS

These Terms of Service (“Terms”) constitute a binding agreement between you, whether individually or on behalf of an entity (“you,” “your,” or “user”), and Tantin Foundation (“Tantin,” “we,” “us,” or “our”), governing your access to and use of Tantin’s services, including the website located at www.tantin.com, as well as any related media, channels, mobile websites, or other platforms connected thereto (collectively, the “Service”). Tantin currently operates www.tantin.com as an informational portal providing news, updates, and resources related to the Tantin protocol and blockchain (the “Tantin Network”) and the broader Tantin ecosystem. The Site may also facilitate access to certain services offered by or through the Foundation. For the avoidance of doubt, Tantin does not control the Tantin Network and cannot influence or oversee activities or data occurring on the network. This includes, without limitation, the actions of individuals or entities building on the Tantin Network, the validation or rejection of transactions, or any other usage or interaction with the Network. The Tantin Network is an open-source, decentralized protocol operated and maintained by independent validators around the world.

BY ACCESSING OR USING THE SERVICE, YOU AGREE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THE TERMS. IF YOU DO NOT AGREE, PLEASE DO NOT USE THE SERVICE.

Supplemental terms and conditions or documents that may be posted on the Service from time to time are hereby expressly incorporated herein by reference. We reserve the right, in our sole discretion, to make changes or modifications to these Terms at any time and for any reason. We will alert you about any changes by updating the “Last updated” date of the Terms, and you waive any right to receive specific notice of each such change. It is your responsibility to periodically review the Terms to stay informed of updates. You will be subject to, and will be deemed to have been made aware of and to have accepted, the changes in any revised Terms by your continued use of the Service after the date such revised Terms is posted.
The information provided on the Service is not intended for distribution to or use by any person or entity in any jurisdiction or country where such distribution or use would be contrary to law or regulation or which would subject us to any registration requirement within such jurisdiction or country. Accordingly, those persons who choose to access the Service from other locations do so on their own initiative and are solely responsible for compliance with local laws, if and to the extent local laws are applicable.
The Service is intended for users who are at least 18 years old. You agree that by using the Service you are at least 18 years of age (or the age of legal majority) or accessing the Service under the supervision of a parent or guardian, and you are legally able to enter into a contract. If you are a parent or legal guardian of a user under the age of 18 (or the age of legal majority), you agree to be fully responsible for the acts or omissions of such user in relation to the Service. If you use the Service on behalf of another person or entity, (a) all references to “you” throughout the Terms will include that person or entity, (b) you represent that you are authorized to accept these Terms on that person’s or entity’s behalf, and (c) in the event you or the person or entity violates these Terms, the person or entity agrees to be responsible to us.
PLEASE NOTE: THE “DISPUTE RESOLUTION” SECTION OF THESE TERMS CONTAINS AN ARBITRATION CLAUSE THAT REQUIRES DISPUTES TO BE ARBITRATED ON AN INDIVIDUAL BASIS, AND PROHIBITS CLASS ACTION CLAIMS. IT AFFECTS HOW DISPUTES BETWEEN YOU AND Tantin ARE RESOLVED. BY ACCEPTING THESE TERMS, YOU AGREE TO BE BOUND BY THIS ARBITRATION PROVISION. PLEASE READ IT CAREFULLY.

ACCESS TO THE SERVICE

Subject to these Terms, we hereby grant you a limited, non-exclusive, revocable, non-transferable, non-sublicensable right and license to access and use the Service for your personal use only, strictly as permitted by the features of the Service. We reserve all rights not expressly granted herein.

TERMINATION OR SUSPENSION OF SERVICE

WITHOUT LIMITING ANY OTHER PROVISION OF THESE TERMS, WE RESERVE THE RIGHT TO, IN OUR SOLE DISCRETION AND WITHOUT NOTICE OR LIABILITY, DENY ACCESS TO AND USE OF THE SERVICE (INCLUDING BLOCKING CERTAIN IP ADDRESSES), TO ANY PERSON FOR ANY REASON OR FOR NO REASON, INCLUDING WITHOUT LIMITATION FOR BREACH OF ANY REPRESENTATION, WARRANTY, OR COVENANT CONTAINED IN THESE TERMS OR OF ANY APPLICABLE LAW OR REGULATION. WE MAY TERMINATE YOUR USE OF OR PARTICIPATION IN THE SERVICE AT ANY TIME, WITHOUT WARNING, IN OUR SOLE DISCRETION. If we terminate or suspend your access to the Service for any reason, you are prohibited from attempting to access the Service under your name, a fake or borrowed name, or the name of any third party, even if you may be acting on behalf of the third party. In addition to terminating or suspending your access, we reserve the right to take appropriate legal action, including without limitation pursuing civil, criminal, and injunctive redress.

CONTENT THROUGH THE SERVICE

(a) Content You Provide
(i) Licenses.
By submitting, posting, or otherwise making available any information, data, or content in any form or medium via the Service—including through features such as the Tantin Assistant or other artificial intelligence-related tools (collectively, “User Content”)—you hereby grant Tantin Foundation a non-exclusive, worldwide, perpetual, irrevocable, royalty-free, fully paid, transferable, and sublicensable license to use, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, display, and perform such User Content and any Output (as defined below), in any media or distribution method now known or developed in the future. You represent and warrant that you have all rights necessary to grant this license, including under all applicable intellectual property and data protection laws.
This license also allows us to make your User Content and Output available to others, and permits other users to access, use, reproduce, display, and distribute your User Content and Output through the Service in accordance with these Terms.
(ii) Responsibility for your User Content
You are solely responsible for the User Content you provide, including the consequences of submitting or sharing it via the Service. Tantin Foundation acts only as a passive conduit for your content and does not assume any responsibility or liability for User Content posted by you or others.
By providing User Content, you affirm, represent, and warrant that:

• You have obtained all necessary permissions and consents, including from any identifiable individuals referenced in your content;

• To the best of your knowledge, all information you provide is accurate and truthful

(b) Content Generated or Accessed Through the Service
(i) AI-Generated Output
Subject to your compliance with these Terms, you may use the output generated by Tantin’s artificial intelligence-related services, including Tantin Assistant (collectively, “Output”), for any lawful purpose on a royalty-free basis. However, you acknowledge and agree that:

• Use of the Service and any Output does not grant you ownership of any intellectual property rights in the Service itself;
• We may, at our sole discretion, limit or revoke your use of the Output at any time if we believe such use may infringe third-party rights;
• You may not represent that the Output was human-generated or use the Output to train any machine learning models.

DUE TO THE NATURE OF MACHINE LEARNING, THE OUTPUT MAY NOT BE UNIQUE ACROSS USERS AND THE SERVICE MAY GENERATE THE SAME OR SIMILAR OUTPUT FOR OTHER USERS. USE OF THE SERVICE MAY RESULT IN INCORRECT OUTPUT THAT DOES NOT ACCURATELY REFLECT REALITY. YOU MUST EVALUATE THE ACCURACY OF ANY OUTPUT AS APPROPRIATE FOR YOUR USE CASE, INCLUDING BY USING HUMAN REVIEW OF THE OUTPUT. YOU UNDERSTAND AND AGREE THAT THE OUTPUT MAY CONTAIN “HALLUCINATIONS” AND MAY BE INACCURATE, OBJECTIONABLE, INAPPROPRIATE, OR OTHERWISE UNSUITED TO YOUR PURPOSE, AND YOU AGREE THAT WE SHALL NOT BE LIABLE FOR ANY DAMAGES YOU OR ANY THIRD PARTY ALLEGES TO INCUR AS A RESULT OF OR RELATING TO ANY OUTPUT.
(ii) General Disclaimers
Any reliance on content (including Output) accessed through the Service is at your own risk. We do not endorse or guarantee the accuracy, reliability, or legality of any such content. By using the Service, you understand you may encounter content that is inaccurate, offensive, or otherwise objectionable.
We do not actively monitor User Content or Output, and we disclaim responsibility for such content. However, we reserve the right to remove content that violates these Terms or that we otherwise determine, at our sole discretion, to be inappropriate for publication on the Service—such as material involving intellectual property infringement, impersonation, unlawful activity, indecent conduct, or harassment.
TESTNET
(a) No Monetary Value
By participating in our Testnet, you may receive “Testnet Tokens” (e.g., via a faucet). These tokens are strictly for testing purposes, hold no monetary value, and cannot and will not convert into mainnet tokens or any other virtual assets. Testnet Tokens are not a form of currency, property, or financial instrument, and are not redeemable, refundable, or exchangeable for fiat, crypto, or anything else of value. You may not sell, trade, transfer, or use Testnet Tokens outside of the Testnet environment. Any attempt to do so will be considered null and void.
(b) Testnet Subject to Change
Tantin reserves the right to modify, suspend, reset, or terminate the Testnet at any time without notice. This includes, but is not limited to, changes in token balances, distribution rules, or other Testnet-related conditions. Tantin offers no guarantee regarding the availability or duration of Testnet Tokens. When the Testnet ends, all Testnet Tokens will be deleted, and users will lose access to them. Testnet Tokens will not carry over into any future rewards or systems offered by Tantin.

Tantin may link or otherwise provide access to products and services offered by third parties through the Service (each, “Third-Party Service”). Further, to use the Service, you may be required to register for Third-Party Services and/or to otherwise enable various Third-Party Services that may directly integrate with the Service. Third-Party Services are not offered by Tantin and Tantin is not responsible for any damages or losses that you might incur as a result of your use or purchase of Third-Party Services. The inclusion of Third-Party Services does not imply Tantin’ endorsement or recommendation of them. If you access or use any Third-Party Service, you do so at your own risk, and you understand that these Terms do not apply to your access to or use of such Third-Party Service. Any engagement with a Third-Party Service is solely between you and the applicable Third-Party Service provider and is subject to such Third-Party Service’s (or Third-Party Service provider’s) own terms and conditions. As such, Tantin is not liable for any damage or loss caused or alleged to be caused by or in connection with your use of or reliance on any Third-Party Service.
You shall and hereby do waive any law in your jurisdiction, which says in substance: “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which, if known by him must have materially affected his settlement with the debtor.” Some jurisdictions do not allow the exclusion of implied warranties, so the above exclusion may not apply to you. You may have other rights which vary from jurisdiction to jurisdiction.

INDEMNIFICATION

You hereby agree to defend, indemnify, and hold Tantin harmless from and against any loss, damage, liability, claim, or demand, including reasonable attorneys’ fees and expenses, made by any third party due to or arising out of: (1) use of the Service; (2) breach of these Terms; (3) any breach of your representations and warranties set forth in these Terms; (4) your violation of the rights of a third party, including but not limited to intellectual property rights; (5) any overt harmful act toward any other user of the Service with whom you connected via the Service; or (6) any breach of, or failure to comply with, applicable law. Notwithstanding the foregoing, we reserve the right, at your expense, to assume the exclusive defense and control of any matter for which you are required to indemnify us, and you agree to cooperate, at your expense, with our defense of such claims. We will use reasonable efforts to notify you of any such claim, action, or proceeding which is subject to this indemnification upon becoming aware of it.

MISCELLANEOUS

These Terms and any policies or operating rules posted by us on the Service constitute the entire agreement and understanding between you and us. Our failure to exercise or enforce any right or provision of these Terms shall not operate as a waiver of such right or provision. These Terms operate to the fullest extent permissible by law. We may assign any or all of our rights and obligations to others at any time. We shall not be responsible or liable for any loss, damage, delay, or failure to act caused by any cause beyond our reasonable control. If any provision or part of a provision of these Terms is determined to be unlawful, void, or unenforceable, that provision or part of the provision is deemed severable from these Terms and does not affect the validity and enforceability of any remaining provisions. There is no joint venture, partnership, employment or agency relationship created between you and us as a result of these Terms or use of the Service. You agree that these Terms will not be construed against us by virtue of having drafted them. You hereby waive any and all defenses you may have based on the electronic form of these Terms and lack of signing by the parties hereto to execute these Terms.
