Labyrinth Terms of Use

Last updated: Jul 31, 2025

Welcome to Labyrinth! These Terms of Use ("Terms") govern your use of the Labyrinth protocol, user interfaces, and any other related software or services (collectively, the "Interface"). The Interface provides privacy-enhancing tools based on zero-knowledge proofs (ZKPs) and selective deanonymization (SeDe). Please read these Terms carefully.

1. Acceptance of Terms

These Terms of Use, along with any documents referenced within (collectively referred to as the “Terms”), govern your access to and use of this Interface. The term "you" or "User" refers to any person, entity, organization, or group that visits, interacts with, accesses, links to, or otherwise benefits from the Interface.

By accessing or using the Interface in any way—including but not limited to browsing, clicking through, or affirming your acceptance—you confirm that you have read, understood, and agreed to comply with these Terms, as well as our Privacy Policy and any Disclosures, which are incorporated by reference.

Please note that by agreeing to these Terms, you also consent to a binding arbitration clause and a waiver of class action rights, both of which affect how legal disputes may be handled.

We reserve the right to update or modify these Terms at any time without prior notice. If you do not accept the most recent version of the Terms, you should discontinue your use of the Interface immediately.

2. Definitions

“User,” “you,” or “your” means any person or entity that accesses or uses the Interface.

“Labyrinth,” “we,” “our,” or “us” refers to the maintainers of the Interface.

“Middleware” means the underlying open-source smart contracts, protocols, or deployments with which the Interface may interoperate.

“ZKP” means zero-knowledge proof systems used to validate statements without revealing the underlying information.

“SeDe” means the selective de-anonymization framework that allows—under defined legal triggers and with a guardian quorum—lawful access to encrypted transactional metadata to trace suspect flows.

“Guardian” means an independent participant in the SeDe framework that contributes to authorization decisions for de-anonymization under a threshold/quorum model.

“Revoker” means the designated entity authorized to perform de-anonymization only upon a publicly verifiable request and approval by the guardian quorum.

3. Dispute Resolution; Arbitration Agreement

If you have any dispute or claim arising out of or relating to the Interface or these Terms, you agree to first attempt to resolve the matter through informal, good-faith negotiations. To initiate this process, you must send an email outlining your concerns to [email protected]. If the dispute is not resolved within 60 days of that initial communication, the matter shall be finally and exclusively resolved by arbitration.

All unresolved disputes shall be submitted to arbitration administered by the Swiss Arbitration Centre in accordance with the Swiss Rules of International Arbitration in effect at the time the arbitration is initiated. The arbitration shall take place in Zug, Switzerland, be conducted in English, and be overseen by a sole arbitrator. The proceedings will remain strictly confidential, and the arbitrator’s decision may be enforced in any court of competent jurisdiction.

This section will continue to apply even after the termination of these Terms, your use of the Interface, or any relationship you may have with the information or services provided through the Interface.

4. Class Action and Jury Trial Waiver

You agree to resolve any disputes or claims related to the Interface solely in your individual capacity. You will not initiate or participate in any class action, collective action, representative proceeding, or action brought on behalf of others, including under any private attorney general theory.

Additionally, you irrevocably waive any right you may have to a trial by jury in connection with any legal action or proceeding arising out of or relating to these Terms or your use of the Interface.

5. Governing Law

You agree that these Terms shall be governed by Swiss law, excluding its conflict of law rules.

6. About the Interface

The Interface is a non-custodial front-end that allows users to interact with smart contracts deployed on EVM-compatible blockchains. Labyrinth enhances transactional privacy while remaining compliant via SeDe mechanisms. Users initiate transactions via connected third-party wallets and remain in full control of private keys.

7. Middleware Relationship

Labyrinth operates as a middleware and SDK suite. Interaction with the Labyrinth smart contracts does not require use of this Interface. Users may interact with the protocol directly via on-chain calls or through third-party integrations.

Labyrinth does not operate validator nodes, manage wallets, or control on-chain deployments. It only provides reference tools and interfaces for developers and end-users.

8. Eligibility

17. Accountable Privacy and Risk Controls

• SeDe & Privacy: Labyrinth’s protocol enables privacy through zero-knowledge proofs while allowing limited, lawful de-anonymization upon guardian-approved legal requests. Logs of requests and approvals are public for transparency.
• Paymaster Mechanics: When enabled, a paymaster may cover transaction fees, deducting charges in the transacted asset based on on-chain logic disclosed at the time of use.
• Screening & Restrictions: The protocol may enforce deposit limits and integrate risk-screening to prevent illicit activity. Interactions may be restricted where risk thresholds are triggered.

18. Key User Risks

• Interface Availability: The Interface is informational, non-custodial, and may be modified or discontinued at any time without notice.
• No Regulatory Oversight: Labyrinth and its maintainers are not registered with or regulated by any governmental or financial authority.
• Legal Uncertainty: Digital assets are subject to evolving regulation. Changes may limit your ability to interact with the Interface or underlying protocols.
• No Warranties: The Interface is provided "as is." There are no guarantees of uptime, accuracy, or freedom from errors.
• Token Identity Risk: Token names and logos may be reused by unrelated contracts. Users must verify contract addresses independently.
• User Responsibility: You are responsible for your wallets, keys, devices, and security practices.
• Fees & Irreversibility: While the Interface itself may not charge fees, blockchain transactions are subject to non-refundable network fees. Paymaster-related charges, if applicable, are non-reversible.
• Accountable Privacy: Privacy protections can be lifted via guardian-approved legal requests, in accordance with the Compliance Policy.
• Sanctions & Risk Screening: Use may be limited based on sanctions and automated risk analysis.

19. License to Use the Interface

You are granted a personal, non-exclusive, non-transferable, revocable license to use the Interface in accordance with these Terms. The underlying smart contracts and SDKs are open-source and not owned by the Interface maintainers.

20. Privacy & Compliance

The Interface may process limited technical data (e.g., logs, wallet/IP addresses) for operational, security, and regulatory purposes. See the Privacy Notice and Compliance Policy for more details.

21. Non-Reliance

You confirm that you are familiar with blockchain systems, have independently evaluated the relevant technologies, and are not relying on the Interface maintainers for advice or guarantees.

22. Disclaimers & Liability Limits

• Third-party Content: The Interface may reference external tools or smart contracts. Use them at your own risk. Labyrinth disclaims responsibility.
• Cryptography Risks: Advances in computing (e.g., quantum) may compromise cryptographic systems.
• Forks: Chain reorganizations may affect your assets. Labyrinth does not commit to supporting forks.
• Third-party Dependencies: The Interface relies on wallets, nodes, and oracles not controlled by its maintainers.
• Taxes: You are solely responsible for understanding and fulfilling your tax obligations.
• Jurisdictional Limitations: Some regions may limit liability disclaimers. These Terms apply only as far as allowed by law.
• Indemnification: You agree to hold Labyrinth and its affiliates harmless against claims, losses, or damages arising from your use of the Interface.

23. Entire Agreement

These Terms, together with the Privacy Notice, Compliance Policy, and any documents referenced herein, form the entire agreement between you and the maintainers regarding use of the Interface, superseding any prior understandings.
