Effective Date: April 6, 2026

These Terms of Service (“Terms”) constitute a legally binding agreement between you (“you,” “your,” or “User”) and Hgraph, Inc., a Delaware corporation (“Hgraph,” “we,” “us,” or “our”). These Terms govern your access to and use of the website located at hgraph.com (“the Website”), our application programming interfaces (“API”), and all related services, tools, documentation, and data (collectively, “the Services”).

By accessing or using the Services, creating an account, or clicking “I agree” (or similar affirmation), you acknowledge that you have read, understood, and agree to be bound by these Terms. If you are using the Services on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

If you do not agree to these Terms, you may not access or use the Services.

Hgraph provides production-grade blockchain infrastructure, including indexed data APIs, analytics, and related tools. The specific features and capabilities available to you depend on your subscription tier, as described in our Fulfillment Policy.

  • Provide accurate, current, and complete information during the registration process

  • Maintain the security and confidentiality of your account credentials and API key
  • Accept responsibility for all activity that occurs under your account

You must be at least 18 years old (or the age of legal majority in your jurisdiction) to create an account and use the Services. By creating an account, you represent and warrant that you meet this requirement.

You may not assign or transfer your account to any other person or entity without our prior written consent. You may not create more than one account per person without our prior written consent.

This indemnification obligation shall survive the termination of these Terms and your use of the Services.

13. Termination

Termination by You

You may terminate your account at any time by following the cancellation procedures described in our Fulfillment Policy or by contacting us at contact@hgraph.com. Termination does not entitle you to a refund of any prepaid fees.

We may suspend or terminate your access to the Services at any time, with or without cause, and with or without notice. Without limiting the foregoing, we may suspend or terminate your access if we reasonably believe: (a) you have violated these Terms or any applicable law; (b) your use poses a security risk to the Services or other users; (c) your account is being used for fraudulent or illegal activity; or (d) continued provision of the Services to you is no longer commercially viable.

Informal Resolution

Before initiating any formal dispute resolution proceedings, you agree to first contact us at contact@hgraph.com and attempt to resolve the dispute informally for at least 30 days. Most disputes can be resolved this way.

Jurisdiction

If a dispute cannot be resolved informally, you agree that any legal action or proceeding arising out of or related to these Terms shall be brought exclusively in the state or federal courts located in the State of Delaware. You consent to the personal jurisdiction and venue of such courts.

Waiver of Class Actions

We reserve the right to modify these Terms at any time. We will notify you of material changes by posting the updated Terms on our Website and updating the Effective Date at the top of this page. For material changes, we will make reasonable efforts to notify you via email or through a prominent notice on the Website at least 30 days before the changes take effect.

Your continued use of the Services after the effective date of any changes constitutes your acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the Services and terminate your account.
