Terms of Use

(as revised on 30.10.2025)

1. Introduction

These Terms of Use (the “Terms”) govern the relationship between the provider of the Services, SHIROI (“SHIROI”, “we,” “us,” “our”), and any person using our services (the “User,” “you,” “your”), whether such person is a natural person, sole proprietor, or legal entity. The Terms set out the basis on which the User is permitted to use, interact with, or otherwise access SHIROI’s services via our official website [domain] and other official resources listed in Section 17 (“Official SHIROI Resources”), as well as in the official documentation. These Terms together with any exhibits, supplemental terms and policies, and documents expressly incorporated by reference (including the Privacy Policy posted on the site) form a legally binding agreement between you and SHIROI. “User” means any person or organization that accesses, uses, interacts with, or views the Services. By accessing any Services, you agree to these Terms, the Privacy Policy posted on the Instrumental Site, the service terms, and other instruments published on SHIROI.io (collectively, the “Site Terms,” and together, the “Site”), as well as the documents expressly incorporated by reference. These documents collectively govern your use of the Services. These Terms apply to your use of the Tools and Services regardless of the channel or point of access (including off-Site access) and regardless of device. From your first access to the Services, you accept these Terms; if you do not agree, discontinue use of the Services. We may unilaterally amend these Terms by publishing an updated version on the Site and/or Instrumental Site stating the date of last update. Unless stated otherwise, changes take effect upon publication. In case of material changes, we may provide additional notice. Continued use of the Services following publication signifies your agreement to the updated version. Attention. By accessing, interacting with, or using the Services, you confirm you have the capacity to enter into a legally binding agreement and that you have read, understood, and accept these Terms, including the documents attached to and supplementing them, the mandatory arbitration agreement, and the class action waiver (see Section 9), to the maximum extent permitted by applicable law. If you act on behalf of an organization, you represent and warrant that you are authorized to bind it to these Terms and to assume responsibility for any breach. If you do not agree in full, do not access or use the Services.

2. Tools and Services

SHIROI provides Tools and Services, as well as programs available in the “SHIROI.labs” repository (together with the Tools and Services, the “Software” or “SOFTWARE”), to operators of nodes on the Solana Network, validators, wallet and application providers, block builders, searchers, and other ecosystem participants.

Definition of “Software.” “Software” means technology and/or software developed by us for:

  • low-latency transaction submission;

  • low-latency transmission of blockchain data and shreds;

  • efficient transaction ordering;

  • ensuring atomicity of cross-transactions;

  • other products in the Solana ecosystem.

Our Services are underpinned by software (the Software) owned by us, with copyrights effective from the time of public discussion, presentations, and publications in our social media and/or in our repository.

We do not represent or warrant that the Tools, Services, or Software will be available uninterrupted, error-free, or for any particular period. To the maximum extent permitted by law, we are not liable to you for any losses, damage, costs, expenses, lost profits and/or missed opportunities, or other harm arising from interruption, delay, failure, error, suspension, or termination of access to the Tools, Services, or Software, including during scheduled or unscheduled maintenance. See Section 8 (Limitations of Liability) for details.

API Credentials. To the extent we provide you with API authentication means or other credentials (“API Credentials”), they are provided on a limited, non-exclusive, revocable, and non-transferable basis solely for your use to lawfully access the Tools and Services in accordance with these Terms and the documentation.

Prohibited:

  • selling, assigning, transferring, lending, publishing, or making API Credentials publicly available;

  • bypassing or altering technical limitations, security mechanisms, or usage limits.

You may disclose secret keys, access tokens, and other API Credentials only to your agents and subcontractors acting for and on your behalf strictly to the extent necessary to perform their tasks. Before disclosure, you must:

  • enter into written confidentiality and Terms-compliance obligations with such persons;

  • implement appropriate oversight of their actions;

  • remain fully responsible for their acts and omissions as if your own.

You must:

  • safeguard and keep API Credentials confidential;

  • restrict access on a need-to-know basis;

  • apply reasonable technical and organizational security measures;

  • promptly notify us of any loss, suspected compromise, or unauthorized use and rotate keys.

We may, at our discretion, suspend, limit, or revoke API Credentials, and modify or set usage limits upon breach of these Terms, security risks, or to prevent abuse. API Credentials and related rights remain the property of SHIROI; their provision grants you no rights other than as expressly set out in the Terms.

3. Modifications

We may amend these Terms at any time in our sole discretion. The updated version will be posted on the Site and/or the documentation site (Instrumental Site) stating the date of last update at the top. Unless expressly stated otherwise, changes are effective upon publication. For material changes, we may additionally post a notice on the Site, within the Services, or send a message to your account contacts if required by law, or without such requirement.

By accessing and using the Services after changes take effect, you consent to the updated version. If you do not agree, you must immediately cease access to and use of the Services. Previously accrued rights and obligations remain in force to the extent permitted by law.

Changes to Services and Tools. We may:

  • modify, suspend, or discontinue the Tools, Services, and/or Software in whole or in part;

  • update, replace, disable, or deprecate features, endpoints, APIs, SDKs, libraries, methods, request/response formats, data schemas, and documentation;

  • remove, modify, or relocate materials in GitHub repositories;

  • adjust methods of interacting with networks and third-party services;

  • introduce, change, or cancel technical limitations (quotas, bandwidth, rate limiting, authentication requirements, security measures).

Scheduled and unscheduled maintenance may cause temporary unavailability. To the maximum extent permitted, SHIROI is not liable for the consequences of such changes; see Section 8.

4. Your Representations and Obligations

Your representations. The Services are intended solely for persons 18+. By accepting the Terms, you confirm your age and, when acting on behalf of a legal entity, your authority to bind it to the Terms and to assume rights and obligations. You further confirm that you:

We may, but are not obligated to, monitor access and use.

5. Intellectual Property Rights

Ownership. The Services, Tools, Software, and related content (excluding third-party content) belong to SHIROI and are protected by intellectual-property laws. You are granted the right to access and use solely for lawful internal purposes and to the extent necessary to interact with the Services. Updates and fixes are provided on the same terms unless expressly stated otherwise. You have no right to:

  • reproduce, distribute, publicly present on your behalf, or publicly discuss;

  • create derivative software;

  • reverse engineer, decompile, or disassemble;

  • circumvent technical protection measures;

  • remove rights notices;

  • use SHIROI marks beyond what is expressly permitted.

Third-party components and/or open-source software are governed by their own licenses—you must comply with them.

License to Use Content for Service Provision. By submitting content or data to us in connection with the Services (“User Content”), you grant us a free, limited, non-exclusive, worldwide permission to use, reproduce, store, modify, technically process, display, and distribute User Content solely to the extent and for the duration objectively necessary to provide, support, improve, and protect the Services and to perform these Terms. You retain all rights to User Content; we acquire no rights beyond those expressly stated. For these purposes, you authorize us to engage affiliates and confidentiality-bound contractors and to provide them with access to Content to the minimum extent required. Upon cessation of your use of the Services, you may request deletion of Content; we will delete it within a reasonable period except for backups and where retention is required by law or reasonably necessary to resolve disputes, ensure security, or enforce the Terms. You confirm you have the necessary rights to User Content and that its submission does not infringe third-party rights. If the Content contains personal data, its processing is carried out in accordance with our Privacy Policy and applicable data-protection law.

SHIROI Trademarks. The name SHIROI, logos, slogans, service names, designs, and other designations are identifiers of SHIROI. Their use is permitted only with our written authorization or per official guidelines.

Your Feedback. By providing feedback, ideas, and suggestions (“Feedback”), you either assign to SHIROI the rights in the Feedback free of charge and irrevocably, or grant a perpetual, worldwide, irrevocable, non-exclusive, royalty-free, sublicensable license to use it without restriction or compensation. You represent you have the rights and that no third-party rights are infringed.

6. Third-Party Information and Services

The Services may integrate with or provide access to third-party services, applications, websites, data, technologies, and features (“Third-Party Services”). We:

  • do not control such resources, nor do we endorse their content;

  • are not responsible for their availability, accuracy, security, legality, or timeliness;

  • may withdraw links and disable integrations without notice.

Access to and use of Third-Party Services are at your own risk and governed by their terms and policies. Relationships arise directly between you and the provider; SHIROI is not responsible for harm/loss from such use to the maximum extent permitted.

Integrations may involve data exchanges. You authorize us to transmit and receive data to the extent necessary to provide, support, improve, and protect the Services. You remain responsible for the lawfulness of data provision, obtaining consents, and complying with data-protection law. Compatibility and continuity of integrations are not guaranteed; third parties may change APIs/protocols. Required changes on your side are your responsibility.

7. Indemnification

General. You agree to defend, indemnify, and hold harmless SHIROI, its affiliates and licensors, and their directors, officers, employees, agents, representatives, and contractors (the “SHIROI Parties”) from any liability and claims for damages, including reasonable fees for legal, audit, and expert services, arising from:

  • your access to, use of, or interaction with the Services;

  • your (or your employees’, agents’, users’, customers’, or engaged persons’) breach of the Terms or law;

  • disputes between you and third parties;

  • infringement or misappropriation of intellectual-property rights, rights of name/reputation, confidential information, or trade secrets;

  • your Feedback, User Content, data, or materials;

  • use of your credentials, including API Credentials;

  • acts and omissions of your outsourcers and subcontractors.

If SHIROI receives a subpoena, compulsory request of a government authority, court order, or other legal process relating to the foregoing, you further reimburse our time and expenses at prevailing hourly rates and reasonable attorneys’ fees.

Process. SHIROI may, at its sole discretion:

  • assume control of the defense and settlement negotiations;

  • determine settlement terms and facts.

You must:

  • promptly notify us of any claim;

  • cooperate fully and in good faith;

  • provide requested information and documents.

No settlement imposing obligations/admissions/encumbrances on SHIROI or restricting public statements is permitted without our written consent. In case of conflict of interest, we may engage separate counsel; its reasonable costs are indemnifiable.

8. Disclaimers and Limitations of Liability

Tools and Services. The Services are provided without warranties of uninterrupted operation, security, availability, or fitness for a particular purpose. Technologies are subject to failures and changes; you assume all risks. We do not warrant that the Services or content are appropriate in your jurisdiction. Security incidents may lead to loss or damage of data—for which we are not liable. We are not responsible for unauthorized access to the Services, including access obtained via fraud/phishing/other criminal acts against you.

We are not liable for failures/delays caused by circumstances beyond our control (force majeure), including natural disasters, war/hostilities, terrorism, civil unrest, states of emergency, epidemics/pandemics, acts of government, sanctions, labor disputes, power outages, cyberattacks and ransomware, telecom/provider failures, carrier limitations, or material shortages. You bear the risk of losses related to use of the Services; changes in the value of cryptoassets, individual transactions, or bundles are outside our responsibility.

Other Disclaimers. Nothing in the Services/Site constitutes an offer, recommendation, or endorsement to buy/sell cryptoassets or other instruments, nor investment, legal, tax, or other professional advice. You act independently and at your own risk.

No Warranties. THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE.” To the maximum extent permitted, we and the other SHIROI Parties disclaim all express, implied, and statutory warranties, including merchantability, satisfactory quality, fitness for a particular purpose, non-infringement, and quiet enjoyment, as well as warranties arising from course of dealing, usage, or trade practice. We do not warrant accuracy, timeliness, completeness, error-free operation, absence of malicious components, preservation of content or feedback.

Liability Limitations. To the maximum extent permitted, the SHIROI Parties are not liable for indirect, punitive, incidental, special, or consequential damages, including:

  • lost profits, revenue, or opportunity;

  • loss of goodwill, data, content, or other assets.

We are also not liable for:

  • inability or delay in using the Services (including termination of the Terms/access, our suspension/termination, downtime);

  • cost of substitute services;

  • your investments, expenses, or obligations under the Terms;

  • unauthorized access to, alteration, deletion, destruction, damage, loss, or failure to store your data;

  • changes in the value of cryptoassets.

In any event, SHIROI’s aggregate liability is limited to USD 100 (one hundred). If any limitation is held invalid, the remaining provisions of this Section continue to apply.

9. Governing Law, Dispute Resolution, and Class-Action Waiver

Governing law (at our discretion). These Terms and any dispute, claim, or disagreement arising out of or relating to them or the Services (a “Dispute”) are governed by the substantive law of the jurisdiction that we designate for the specific Dispute in our written notice, without regard to conflict-of-laws rules—to the extent such choice is permitted by applicable law. If we do not designate the law for a specific Dispute or such choice is invalid, the default governing law is the substantive law of Switzerland (without conflict-of-laws rules).

Amicable resolution. Disputes are to be resolved consensually through voluntary out-of-court procedures.

Pre-litigation procedure. Either party undertakes to seek good-faith resolution by joint agreement: • The initiating party sends written notice describing the claims and grounds. • A response is provided within 20 calendar days. • Within 45 days from notice, the parties negotiate and make reasonable efforts to settle. • If within 90 days no settlement is reached, the parties may agree to mediation; only in exceptional cases and absent agreement may a party file for arbitration under Section 9. These periods do not preclude seeking interim injunctive relief (see Section 9).

Arbitration (tribunal)—at our option. We may, at our discretion, refer any Dispute to arbitration. In that case: • Institution and rules: as we designate (e.g., ICC, LCIA, SIAC, HKIAC) or ad hoc under the UNCITRAL Rules. • Seat of arbitration: as we designate; if none, Geneva, Switzerland. • Language: as we designate; if none, English. • Tribunal: one arbitrator; if claims exceed the equivalent of USD 1,000,000—three arbitrators. • Procedure and timelines: the parties and tribunal will aim for expedited, economical, and confidential proceedings; remote hearings and electronic filings are permitted. • Enforcement: the award is final and enforceable by courts of any competent jurisdiction. Nothing herein prevents recourse to courts for interim measures (see Section 9).

Judicial forum (if not arbitration)—at our option. If a Dispute is not referred to arbitration under Section 9, it shall be brought in the state courts of the jurisdiction we designate for the specific Dispute. You irrevocably agree to such forum and waive objections based on forum non conveniens to the extent permitted by law.

Interim measures and protection of rights. Regardless of forum, either party may at any time seek interim measures (including injunctive relief) in the courts of any competent jurisdiction, as well as protection of intellectual-property and confidential-information rights. Seeking such relief is not a waiver of arbitration/jurisdiction on the merits.

Consumers and mandatory norms. If you act as a consumer, nothing herein deprives you of the protection of mandatory laws of your habitual residence and the right to bring claims in local courts where such right is granted by law. Where mandatory rules disallow arbitration and/or court waivers for consumers, such rules apply and any contrary provisions here do not.

Class-action waiver. To the extent permitted by law, Disputes are resolved solely on an individual basis; class, collective, representative, consolidated, or joint proceedings, as well as “class” arbitration, are not permitted. The arbitrator (or court) is not authorized to consolidate cases, preside over a class proceeding, or issue relief for persons outside your individual matter. The parties waive jury trial where such waiver is permitted.

Severability and conformity. If any provision of this Section is held invalid or unenforceable, it shall be modified to the minimum extent necessary to conform with applicable law, and the remaining provisions continue in force.

10. No Relationship

Nothing in the Terms creates relationships other than those expressly stated. The Terms do not constitute a partnership, joint venture, employment, franchise, agency, mandate, association, or fiduciary relationship. The parties act as independent contractors. You are not authorized to act on behalf of SHIROI or bind us without our written consent.

11. Assignment and Transfer

You may not assign, transfer, delegate, or pledge rights or obligations under the Terms without our prior written consent; any attempt otherwise is void. SHIROI may assign, transfer, or delegate rights and obligations without your consent, and may engage affiliates and subcontractors. The Terms bind permitted successors and assigns.

12. Entire Agreement

These Terms and documents incorporated by reference constitute the entire and exclusive agreement between you and SHIROI on the subject matter and supersede prior arrangements. Other statements, promises, and marketing materials have no legal effect unless set out in writing by an authorized representative of SHIROI. Amendments are effective only in writing and upon publication on the Site/Instrumental Site or execution of a separate document. In case of conflict with special terms, such special terms prevail as to the relevant element. Section headings do not affect interpretation.

13. No Waiver

Failure or delay in exercising a right is not a waiver and does not prevent further exercise. A single/partial exercise does not preclude any other/further exercise. A waiver by SHIROI is effective only if expressly in writing and only for the specific instance. Rights and remedies under the Terms supplement those provided by law.

14. Severability

If any provision is invalid, illegal, or unenforceable, the remainder remains in force. Such provision shall be applied to the maximum extent to effectuate the original intent; if impossible, it is deemed severed without affecting the rest. Invalidity in one jurisdiction does not affect validity elsewhere.

15. Notices

You agree to receive communications from us electronically. We may send notices to the email of your account and/or post them within the Services, on the Site, and/or Instrumental Site. Emails are deemed received upon sending absent bounce-back; posted notices upon publication. You will keep contact details current and ensure receipt of emails from SHIROI domains. We are not responsible for non-receipt due to reasons within your control.

Legally significant notices from you must be sent to [insert contact address/form] and are deemed received upon actual receipt. Where paper form is required, send to our postal/legal address listed on the Site; receipt is deemed upon delivery per the carrier’s records.

16. Contact Us

Questions about the Terms or Services: [email protected]. You may use the feedback form on the Site and/or Instrumental Site (if available) or the contacts listed there. Do not send seed phrases, private keys, passwords, 2FA codes, payment-card data, or other secrets. We never request them. Support inquiries do not replace the notice procedure in Section 15 and do not create obligations to respond within a set period. Messages may be recorded and processed by us/affiliates to provide, improve, and protect the Services.

17. Official SHIROI Resources

Only the channels listed below are “Official SHIROI Resources.” Any other sites, accounts, chats, bots, mirrors, and domains are not official. — Site: https://shiroi.io/ — Instrumental Site: https://docs.shiroi.io — Discord server: soon — Telegram channel/chat: https://t.me/shiroi_official / https://t.me/shiroi_official_chat — GitHub: https://github.com/shiroi-labs — Support: [email protected]

We may update this list by publishing changes in this section. In case of discrepancies between third-party information and the Site/Instrumental Site, the Site and Instrumental Site prevail. SHIROI does not communicate “via admin DMs” and does not request seed phrases, private keys, passwords, or 2FA codes; communications from resources not listed above should be treated as unauthorized.
