By accessing or using the Service, you agree to be bound by these Terms and our Privacy Policy. If you are accepting these Terms on behalf of an organization, you represent and warrant that you have the authority to bind that organization. If you do not agree to these Terms, you must not access or use the Service.

2. Definitions

  • "Analysis Output" means decompiled source code, vulnerability reports, security findings, exploit validation results, fuzzing results, and any other data generated by the Service from your Analysis Inputs.
  • "Analysis Inputs" means contract addresses, bytecode, network identifiers, configuration parameters, and any other data you submit to the Service for processing.
  • "API" means the programmatic interfaces provided by Sigvex for accessing Service functionality.
  • "Content" means all text, data, code, images, and other materials available through the Service, whether provided by Sigvex, Users, or derived from blockchain networks.

The Service analyzes publicly available on-chain bytecode. Analysis Output is generated through automated processes and is provided for informational and defensive security purposes.

4. Eligibility

You must be at least 16 years of age to use the Service. By using the Service, you represent and warrant that you meet this age requirement, have the legal capacity to enter into these Terms, and are not prohibited from using the Service under any applicable law or regulation (including export control and sanctions laws).

5. Account Registration and Security

  • Certain features of the Service require you to create an account. You must provide accurate and complete registration information.
  • You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.
  • You must notify us immediately of any unauthorized use of your account or any other security breach.
  • We may suspend or terminate accounts that violate these Terms, exhibit suspicious activity, or remain inactive for an extended period.
  • You may not share account credentials or allow multiple individuals to use a single account unless your Subscription expressly permits team access.

6. Acceptable Use

You agree to use the Service only for lawful purposes and in compliance with these Terms and our Acceptable Use Policy. You agree not to:

  • Use the Service to facilitate unauthorized access to any system, network, or smart contract, or to exploit vulnerabilities in live contracts without explicit authorization from the contract owner.
  • Use vulnerability findings, exploit outputs, or any Analysis Output to steal funds, cause financial loss, or engage in any illegal activity.
  • Attempt to disrupt, degrade, overload, or impair the Service or its underlying infrastructure, including through denial-of-service attacks or excessive automated requests.

If you access the Service through our APIs, the following additional terms apply:

  • API Keys: API keys are issued to you personally (or to your organization) and must not be shared, published, or embedded in client-side code.
  • Rate Limits: API usage is subject to rate limits as documented in our API documentation. Exceeding rate limits may result in temporary throttling or suspension of API access.
  • Availability: APIs are provided on an "as available" basis. We may modify, deprecate, or discontinue API endpoints with reasonable notice. Breaking changes will be communicated in advance where feasible.
  • Attribution: If you display Analysis Output generated through the API in a public-facing application, you must include attribution to Sigvex unless your Subscription terms state otherwise.
  • Compliance: You are responsible for ensuring that your use of the API complies with these Terms and all applicable laws.

9. Intellectual Property

9.1 Sigvex Intellectual Property

The Service, including its source code, algorithms, detection methods, user interface design, documentation, and branding (logos, trademarks, trade names), is the proprietary property of Sigvex and is protected by intellectual property laws. All rights not expressly granted in these Terms are reserved.

9.2 Your Content and Inputs

You retain ownership of any Analysis Inputs you submit to the Service. By submitting Analysis Inputs, you grant Sigvex a limited, non-exclusive, worldwide license to process, store, and use those inputs solely as necessary to provide the Service and improve our analysis capabilities (in aggregated, anonymized form).

9.3 Analysis Output

10. Trademarks

The Sigvex name, logo, and all related trademarks, trade names, service marks, and trade dress displayed on the Service are the property of Sigvex. You may not use any Sigvex trademark without our prior written consent. Nothing in these Terms grants you any right or license to use any Sigvex trademark for any purpose.

Other trademarks, product names, and company names or logos appearing on the Service are the property of their respective owners. Reference to any third-party products, services, or trademarks does not constitute or imply endorsement, sponsorship, or recommendation.

WITHOUT LIMITING THE FOREGOING:

  • We do not warrant that Analysis Output is complete, accurate, or free of false positives or false negatives. Automated security analysis has inherent limitations.
  • We do not warrant that the Service will detect all vulnerabilities in analyzed contracts. The absence of findings does not mean a contract is secure.
  • Decompiled source code is a best-effort approximation and may not exactly reproduce the original source code or reflect the developer's intent.
  • We do not warrant that the Service will be uninterrupted, timely, secure, or error-free.
  • We do not endorse, verify, or guarantee the security, functionality, or legitimacy of any smart contract analyzed through the Service.

You acknowledge that the Service should be used as one component of a comprehensive security review process and not as a sole or definitive security assessment. Decisions based on Analysis Output are made at your own risk.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SIGVEX, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION:

  • Loss of profits, revenue, data, goodwill, or anticipated savings.
  • Financial losses resulting from reliance on Analysis Output, including losses from exploited vulnerabilities that the Service failed to detect.
  • Losses resulting from unauthorized access to or alteration of your data.
  • Losses arising from actions taken by third parties based on Analysis Output you shared.
  • Cost of procurement of substitute services.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED US DOLLARS (USD $100).

These limitations apply regardless of the legal theory (contract, tort, strict liability, or otherwise), even if we have been advised of the possibility of such damages.

15. Indemnification

You agree to indemnify, defend, and hold harmless Sigvex and its officers, directors, employees, agents, and affiliates from and against any third-party claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to:

18. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of England and Wales, without regard to conflict of law principles.

Any dispute arising out of or relating to these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If the dispute cannot be resolved within 30 days of written notice, either party may submit the dispute to the exclusive jurisdiction of the courts of England and Wales.

Nothing in this section prevents either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to prevent the actual or threatened infringement of intellectual property rights.

19. Changes to These Terms

We may update these Terms from time to time. When we make material changes:
