Welcome to the Kaiko Data On-Ramp Services (the “Service”), provided by Challenger Deep SAS (“Kaiko”, “we”, “us”, or “our”), registered under French SIRET number 80738837600061 and headquartered at 128 rue La Boétie, 75008 Paris, France. These Terms of Use (the “Terms”) govern your access to and use of the Service. By accessing or using the Service, you (“User” or “you”) agree to be bound by these Terms. If you do not agree to these Terms, you must not access or use the Service.

SECTION 1 – SCOPE OF THE SERVICE
The Service is a production service that makes certain off-chain data feeds available through blockchain-based interfaces, including smart contracts, oracle mechanisms, APIs, and other technical infrastructure. The Service may include Kaiko data products and data products supplied by third-party data owners or licensors. The available data may include market data, pricing information, reference data, fair market value data, and other information identified in the applicable product documentation or commercial terms.
The Service may operate across multiple blockchain networks and may support additional networks from time to time. Unless expressly stated otherwise in the applicable product documentation or commercial terms, these Terms apply equally to the Service and to your use of the Service on each supported network. Network-specific technical requirements, limitations, fees, operating conditions, and risks may nevertheless differ between networks.
The Service and its data coverage, supported networks, technical architecture, and functionality may be updated, suspended, or discontinued in whole or in part. Kaiko does not guarantee that any particular data feed, network, endpoint, smart contract, or feature will remain available or continuously available.

SECTION 2 – LICENSE AND ACCESS
The Service may be technically accessible without a login, account, or other front-end access control. Technical accessibility does not, however, grant you a right to access or use any particular data feed. Access to a data feed is functionally subject to your having all licences, permissions, and other rights required for that feed and for your intended use of it.
Kaiko may verify your entitlement to access a data feed through a dedicated entitlement-verification process. Depending on the relevant data source and technical implementation, that process may rely on an account, API key, wallet address, smart-contract interaction, credential, contractual identifier, or other identifier or verification method. If you are not properly licensed or otherwise entitled to access the relevant feed, the Service may reject your request, withhold the data, return an error, or restrict your use of the data.
The applicable rights to use a data feed may be granted by the owner or licensor of the relevant data product, whether Kaiko or a third party. Kaiko may provide the technical infrastructure through which a third-party data product is made available but does not, solely by making that product technically accessible, grant rights that are owned or controlled by the relevant third-party data owner or licensor. Your use of each data feed is subject to the applicable data-feed licence, order form, product terms, documentation, or other contractual terms governing that feed.
You must not attempt to circumvent, disable, interfere with, or otherwise defeat any entitlement-verification, authentication, access-control, or licensing mechanism. The fact that data or transaction information may be visible on a blockchain or otherwise technically retrievable does not grant you any ownership or licence to use that data.
Subject to these Terms and the applicable data-feed licence, Kaiko grants you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable right to access and use the Service for the permitted purposes expressly authorised for the relevant data feed. No broader licence is granted by implication, estoppel, or otherwise.

SECTION 3 – FEES AND PAYMENT
You are solely responsible for all fees charged by a blockchain network or other infrastructure provider in connection with your access to or interaction with the Service, including gas fees, transaction fees, validation fees, execution fees, and other network or infrastructure charges. Kaiko does not subsidise these fees. Such fees are generally payable directly to the relevant network or infrastructure provider and may vary depending on network conditions, transaction complexity, congestion, and other factors outside Kaiko’s control.
The applicable data owner or licensor may impose a fee or mark-up in connection with access to a data feed. Where applicable, Kaiko may also impose a fee or mark-up in connection with the provision, operation, maintenance, or support of the Service, including to support the economic and operational viability of the Service on the relevant networks. Any applicable fee, pass-through charge, or mark-up will be identified in the applicable product documentation, commercial terms, user interface, transaction flow, or other notice made available to you before or at the time it becomes payable, to the extent reasonably practicable.
You are responsible for confirming the applicable fees before initiating a transaction or requesting access to a data feed. Kaiko is not responsible for losses arising from network fees, third-party charges, changes in network conditions, or your failure to review applicable fees before using the Service.

SECTION 4 – ELIGIBILITY AND COMPLIANCE
By using the Service, you represent and warrant that you and that your use of the Service complies with all applicable laws, regulations, sanctions, contractual restrictions, and licensing requirements.
You must not use the Service where its provision or your use of it is prohibited by applicable law or regulation, or where doing so would cause Kaiko or any data owner or licensor to breach an applicable legal, regulatory, contractual, or licensing obligation.

SECTION 5 – INTELLECTUAL PROPERTY AND DATA RIGHTS
The Service and its components, including software, source and object code, smart contracts, APIs, interfaces, documentation, methodologies, databases, data compilations, trademarks, logos, designs, metadata, attestations, signatures, proofs, and other materials, are owned by Kaiko, its affiliates, or their respective licensors and are protected by applicable intellectual-property and other laws.
No ownership, title, or other proprietary interest in the Service, any data feed, or any associated material is transferred to you. Except for the limited rights expressly granted under these Terms and the applicable data-feed licence, you may not copy, reproduce, modify, adapt, translate, distribute, publish, transmit, display, perform, sell, license, sublicense, create derivative works from, reverse engineer, disassemble, decompile, extract, aggregate, or otherwise exploit the Service or any data or material made available through it.
Your use of a data feed is subject to all restrictions, limitations, attribution requirements, use-case limitations, redistribution restrictions, and other conditions imposed by the applicable data owner or licensor. Those restrictions and limitations apply whether the relevant data is accessed directly from Kaiko, through a third-party interface, through a blockchain network, or through any other part of the Service. Where a data-feed licence or other applicable contractual terms impose more specific requirements than these Terms, those more specific requirements will apply to the relevant data feed.
The Kaiko name, logo, and other Kaiko trademarks and service marks may not be used without Kaiko’s prior written consent. Nothing in these Terms grants you any right to use Kaiko’s branding or the branding of any data owner or licensor.

SECTION 6 – PROHIBITED USES
You must not use the Service, any data feed, or any associated artifact in a manner that:
Violates any applicable law, regulation, sanction, court order, contractual restriction, data-feed licence, or other legal obligation;
Accesses, uses, copies, redistributes, publishes, commercialises, or otherwise exploits a data feed without the licence, entitlement, or permission required for that use;
Circumvents, disables, interferes with, or defeats any entitlement-verification, authentication, access-control, payment, licensing, or technical protection mechanism;
Uses a data feed for a purpose, in a jurisdiction, or in a manner prohibited by the applicable data-feed licence or by the relevant data owner or licensor;
Uses, displays, republishes, transmits, or otherwise makes use of a fetched data point without the associated artifact propagated by Kaiko with that data point, including the relevant on-chain attestation, signature, proof, metadata, or other integrity or entitlement artifact (the “Associated Artifact”);
Separates, strips, suppresses, alters, obscures, or removes the Associated Artifact from a data point, or uses the data point after the Associated Artifact has been removed or is no longer available for verification;
Scrapes, mines, harvests, systematically extracts, indexes, aggregates, or automates access to the Service or any data feed, except as expressly authorised in writing by Kaiko and permitted by the applicable data-feed licence;
Interferes with, disrupts, overloads, damages, or attempts to gain unauthorised access to the Service, any network, smart contract, server, endpoint, or related infrastructure;
Reverse engineers, decompiles, disassembles, or attempts to discover the source code, algorithms, methodologies, or underlying structure of the Service, except to the extent that such restriction is prohibited by applicable law; or
Involves fraud, deception, market abuse, money laundering, terrorist financing, sanctions evasion, or any other harmful or unlawful activity.
Kaiko may suspend or terminate your access to the Service, refuse or limit requests, invalidate or disable credentials, and take any other action reasonably necessary to protect the Service, Kaiko, its licensors, the relevant networks, or other users if you engage in a prohibited use or if Kaiko reasonably believes that you have done so.

SECTION 7 – DISCLAIMERS
The Service, each data feed, and all associated materials are provided on an “as is” and “as available” basis. To the fullest extent permitted by applicable law, Kaiko disclaims all representations, warranties, and conditions, whether express, implied, statutory, or otherwise, including those relating to accuracy, completeness, timeliness, reliability, availability, uninterrupted operation, fitness for a particular purpose, merchantability, satisfactory quality, title, non-infringement, and suitability for your intended use.
Data may contain errors, omissions, delays, interruptions, or inaccuracies and may be changed, corrected, or withdrawn without notice. Kaiko does not warrant that any data, data point, Associated Artifact, smart contract, endpoint, or network interaction will be available, error-free, secure, or suitable for any particular application or transaction.
The Service provides information and technical infrastructure only. It does not constitute financial, investment, legal, tax, accounting, trading, or other professional advice, and it should not be relied upon as the sole basis for any decision or transaction.

SECTION 8 – TECHNOLOGY AND NETWORK RISKS
The Service depends on blockchain networks, smart contracts, wallets, nodes, cryptographic systems, telecommunications networks, third-party infrastructure, and other technologies that may be affected by bugs, exploits, cyberattacks, congestion, forks, reorganisations, validator or node failures, oracle failures, loss of keys, changes to network rules, or other events. These risks may result in delays, failed or irreversible transactions, inaccurate or unavailable data, loss of access, or loss of digital assets or fees.
You are solely responsible for assessing the risks of using the relevant network and for ensuring that your wallet, systems, applications, integrations, and security practices are appropriate for your use of the Service. Your use of the Service constitutes your acknowledgement and acceptance of these risks.

SECTION 9 – LIMITATION OF LIABILITY
To the fullest extent permitted by applicable law, Kaiko and its affiliates, officers, directors, managers, employees, agents, contractors, licensors, and service providers (together, the “Kaiko Parties”) will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, business, opportunity, goodwill, anticipated savings, data, digital assets, or fees, arising out of or relating to the Service, any data feed, any Associated Artifact, or these Terms, whether arising in contract, tort, negligence, strict liability, statute, or otherwise, even if advised of the possibility of such loss.
To the fullest extent permitted by applicable law, the Kaiko Parties will not be liable for any loss or damage resulting from your use of, or inability to use, the Service; reliance on any data or Associated Artifact; network fees or third-party charges; network conditions, failures, reorganisations, or attacks; unauthorised access to your systems or wallet; or any act or omission of a data owner, licensor, network operator, node provider, or other third party.
To the extent liability cannot lawfully be excluded or limited, it will be limited to the maximum extent permitted by applicable law. Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited.

SECTION 10 – INDEMNIFICATION
You agree to indemnify, defend, and hold harmless the Kaiko Parties from and against claims, proceedings, liabilities, damages, losses, costs, and expenses, including reasonable legal fees, arising out of or relating to your use of the Service, your use or misuse of any data feed or Associated Artifact, your breach of these Terms or an applicable data-feed licence, your violation of applicable law or third-party rights, or your acts or omissions in connection with the Service.

SECTION 11 – DATA PRIVACY
Kaiko processes personal data in accordance with its applicable Privacy Policy. By using the Service, you acknowledge that personal data may be processed as described in that Privacy Policy, including for account management, entitlement verification, security, fraud prevention, service operation, compliance, and support purposes.

SECTION 12 – CHANGES TO THESE TERMS
Kaiko may amend these Terms from time to time. Any amended Terms will become effective when posted or otherwise made available, unless a later effective date is specified. Your continued use of the Service after the effective date of amended Terms constitutes your acceptance of those amendments. If an amendment materially affects your rights or obligations, Kaiko may provide additional notice where reasonably practicable.

SECTION 13 – SUSPENSION AND TERMINATION
Kaiko may suspend, restrict, or terminate your access to all or part of the Service, with or without notice, if you breach these Terms, exceed your entitlement, fail to pay applicable amounts, engage in a prohibited use, create a security or legal risk, or if suspension or termination is necessary due to a change in the Service, a data-owner or licensor requirement, a network issue, or applicable law.
Upon suspension or termination, you must immediately cease using the Service and the affected data feed, including any Associated Artifacts, except to the extent that continued retention or use is expressly permitted by the applicable data-feed licence or required by law. Provisions that by their nature should survive termination will survive, including provisions concerning intellectual property, prohibited uses, disclaimers, limitation of liability, indemnification, governing law, and dispute resolution.

SECTION 14 – GOVERNING LAW AND DISPUTE RESOLUTION
These Terms are governed by and construed in accordance with the laws of France, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the Service will be submitted to the exclusive jurisdiction of the competent courts of Paris, France, subject to any mandatory rules of applicable law.
