Interface terms of use

‍
Last updated 26.02.2026

These Terms of Use together with any documents incorporated by reference herein(“Terms”) constitute a legally binding agreement between Zama (“Company”) and you("User", "you” or "your");

The Company and the User are hereinafter collectively referred to as the "Parties" andindividually as a "Party".

By ticking the acceptance box, connecting a digital wallet and/or using the Interface, youconfirm and acknowledge that you have carefully read these Terms, fully understand theircontent and effect, and expressly agree to be legally bound by them.

1. Interface

The web-based interface made available on the Company’s website (“Interface”) provides a visual display and a technical means of interacting with the Zama Protocol as well as related smart contracts, deployed on the Zama Protocol or on other distributed-ledger networks supported by the Zama Protocol (“Related Smart-Contracts”).

Use of the Interface is optional and undertaken solely at the User’s own initiative and risk.

The Interface is functionally and legally distinct from the Zama Protocol and the Related Smart Contracts. The Interface is one, but not the exclusive, means of interacting with the Zama Protocol and the Related Smart Contracts. The Zama Protocol and the Related Smart Contracts referenced or visualized through the Interface are autonomous, self-executing software that operate independently of the Interface.   

The Company does not operate, control, execute or have any ability to influence the execution of any transactions on the Zama Protocol or the Related Smart Contracts, nor does it have control over any digital assets, or tokens of the User.

2. Eligibility

By accessing or using the Interface, you represent and warrant to the Company, both at the time of first access and continuously throughout your use, that:

  • You are at least eighteen (18) years old or have reached the age of majority as defined by the laws of your country of residence, and possess full legal capacity to enter into these Terms and to use the Interface;
  • Neither you nor any of your affiliates, officers or directors are (i) a citizen or resident of, or located in, any jurisdiction subject to comprehensive sanctions or embargoes imposed by the United Nations, Switzerland, the European Union, the United States, or any other relevant governmental or regulatory authority; or (ii) domiciled in, or organized under the laws of, any jurisdiction whose laws or regulations conflict with these Terms or the use of the Interface;
  • Neither you nor any of your affiliates, officers or directors (i) are listed on or owned or controlled by any person or entity listed on, the Swiss State Secretariat for Economic Affairs (SECO) Overall List of Sanctioned Individuals, Entities and Organizations, the EU Consolidated List of Persons, Groups and Entities Subject to EU Financial Sanctions, the U.S. Department of Commerce Denied Persons or Entity List, the U.S. Department of the Treasury Specially Designated Nationals or Blocked Persons List, the U.S. Department of State Debarred Parties List, or any equivalent national or international sanctions or embargo list; or (ii) are a resident, citizen, or located in any geographic area designated by the Financial Action Task Force (FATF) or any similar intergovernmental organization as non-cooperative with international anti-money laundering principles or procedures; and
  • All digital assets, funds, or value associated in any way with your use of the Interface are of lawful and legitimate origin, are not derived from or connected to any criminal, fraudulent, or otherwise unlawful activity, and do not constitute or result from any act that may constitute a breach of anti-money-laundering or counter-terrorist-financing laws or regulations, whether under the laws of the jurisdiction of origin, the laws of any relevant jurisdiction, or under applicable international standards.

You acknowledge and agree that providing false, inaccurate, or misleading representations or warranties constitutes a material breach of these Terms. The Company may, at its sole discretion and without prior notice, to immediately suspend or restrict your access to the Interface if it reasonably believes that any such representations or warranties have been breached or are no longer accurate. The Company shall not be liable for any loss, damage, or expense arising from or related to measures taken in good faith pursuant to this provision.

3. Zama Protocol and Related Smart Contracts

The Zama Protocol and the Related Smart Contracts referenced, displayed, or accessible through the Interface are independent decentralized systems not managed, or controlled by the Company. 

The Company has no ability to access, custody, transfer, execute, initiate, approve, lock, unlock, or otherwise control any tokens or transactions on the Zama Protocol and on any Related Smart Contracts. All interactions with the Zama Protocol and the Related Smart Contracts are governed exclusively by the autonomous code and logic of the Zama Protocol and the Related Smart Contracts.

If the User loses access to, misplaces or compromises the private keys, recovery credentials or other means of authentication associated with a wallet, any tokens associated with or linked to that wallet may be permanently inaccessible. In such circumstances, the affected tokens cannot be recovered, restored, or otherwise accessed by the Company under any circumstances. 

You are solely responsible for maintaining the confidentiality, integrity, security, and control of any wallets, private keys, recovery phrases, passwords, or credentials used in connection with the Interface. The Company assumes no responsibility or liability for any unauthorized access, loss, theft, or compromise resulting from your actions, omissions, or security failures.

By using the Interface, you expressly acknowledge and accept the irreversible nature of distributed-ledger transactions and assume full responsibility for safeguarding your private keys, wallets, and access credentials. You further acknowledge that interactions with the Zama Protocol and the Related Smart Contracts may be irreversible, may result in permanent loss of tokens, and may be affected by bugs, design limitations, security vulnerabilities, upgrades, forks or other modifications in the underlying distributed-ledger networks.

4. No Offer, No Solicitation, No Recommendation

The Interface does not constitute, and shall not be construed as, an offer, solicitation, recommendation, or invitation to purchase, sell, exchange, hold, or otherwise engage in any transaction involving tokens or other digital assets. 

Any use of the Interface is undertaken solely at the User’s own initiative and risk , and the Company makes no representation or warranty that such use is lawful or appropriate in any particular jurisdiction.

Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world.If two parties have some sort of dealings, then each has a memory of their interaction. Each party can speak about their own memory of this; how could anyone prevent it? One could pass laws against it, but the freedom of speech, even more than privacy, is fundamental to an open society; we seek not to restrict any speech at all. If many parties speak together in the same forum, each can speak to all the others and aggregate together knowledge about individuals and other parties. The power of electronic communications has enabled such group speech, and it will not go away merely because we might want it to.Since we desire privacy, we must ensure that each party to a transaction have knowledge only of that which is directly necessary for that transaction. Since any information can be spoken of, we must ensure that we reveal as little as possible. In most cases personal identity is not salient. When I purchase a magazine at a store and hand cash to the clerk, there is no need to know who I am. When I ask my electronic mail provider to send and receive messages, my provider need not know to whom I am speaking or what I am saying or what others are saying to me; my provider only need know how to get the message there and how much I owe them in fees. When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself.Therefore, privacy in an open society requires anonymous transaction systems. Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy.Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one's identity with assurance when the default is anonymity requires the cryptographic signature.We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor.We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can't get privacy unless we all do, we're going to write it. We publish our code so that our fellow Cypherpunks may practice and play with it. Our code is free for all to use, worldwide. We don't much care if you don't approve of the software we write. We know that software can't be destroyed and that a widely dispersed system can't be shut down.Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. The act of encryption, in fact, removes information from the public realm. Even laws against cryptography reach only so far as a nation's border and the arm of its violence. Cryptography will ineluctably spread over the whole globe, and with it the anonymous transactions systems that it makes possible.For privacy to be widespread it must be part of a social contract. People must come and together deploy these systems for the common good. Privacy only extends so far as the cooperation of one's fellows in society. We the Cypherpunks seek your questions and your concerns and hope we may engage you so that we do not deceive ourselves. We will not, however, be moved out of our course because some may disagree with our goals.The Cypherpunks are actively engaged in making the networks safer for privacy. Let us proceed together apace.Onward.Eric Hughes9 March 1993
