Fungibull.ai — Terms and Conditions

Last updated May 25, 2026

These Terms and Conditions (the “Terms”) constitute a legally binding agreement between you (the “User”, “you”, “your”) and Vtail Ltd (“we”, “us”, “our”, registered at 20-22 Wenlock Road, London, N1 7GU, United Kingdom) governing your access to and use of the Fungibull.ai website, application, and any related services, tools, or features operated under the Fungibull brand (collectively, the “Service”).

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use the Service.

We may update or modify these Terms at any time. When we make changes, we will update the “Last Updated” date above and may notify you through the Service, by email, or by other means we deem appropriate. Your continued use of the Service after any changes constitutes acceptance of the updated Terms. If you do not agree to the revised Terms, you must stop using the Service immediately.

“Wallet Address” means any public blockchain address or blockchain-based naming identifier (such as a domain or alias registered on any supported naming service) submitted by a User to the Service for a persona reveal.

“Reveal” means the process by which the Service analyses a Wallet Address and generates a Persona Card.

“AI-Generated Content” means all text, descriptions, personality profiles, roasts, predictions, and other written content produced by artificial intelligence as part of the Service.

“Platform” means the Fungibull.ai website, any associated subdomains (including fungibull.com), mobile applications, and any other interfaces through which the Service is made available.

2. The Service

Fungibull.ai is a tool that generates personality-based persona cards from publicly available blockchain wallet data. Users submit a public wallet address, and the Service retrieves on-chain data and uses AI to generate a unique persona card with an archetype, personality traits, statistics, and commentary.

Certain features of the Service may be available without creating an account. Other features may require account registration. We reserve the right to change which features require an account at any time.

3. Entertainment Purpose Only — Not Financial Advice

THE SERVICE IS DESIGNED PURELY FOR ENTERTAINMENT, SOCIAL SHARING, AND FUN. IT IS NOT A FINANCIAL TOOL, INVESTMENT SERVICE, PORTFOLIO TRACKER, TRADING PLATFORM, OR ADVISORY SERVICE OF ANY KIND.

All content generated by the Service — including persona cards, archetype classifications, personality descriptions, roasts, predictions, statistics, trait assessments, and any other AI-generated or data-derived output — is created for entertainment purposes only. None of it constitutes, and none of it should be interpreted as:

  • Financial, investment, tax, or legal advice of any kind.
  • A recommendation, endorsement, or assessment of any cryptocurrency, token, NFT, blockchain project, or digital asset.
  • A factual, accurate, or reliable assessment of any individual’s financial behaviour, trading ability, portfolio performance, or net worth.
  • A personality assessment, psychological profile, or any form of professional analysis.
  • An indication or prediction of future financial performance or market outcomes.

The persona cards and all associated content are generated by AI based on publicly available blockchain data and may be inaccurate, incomplete, exaggerated, humorous, or entirely fictional. You should not rely on any content from the Service for financial decisions, investment choices, or any other consequential purpose.

The Service is intended for you to enjoy, share with friends, and post on social media for fun. By using the Service, you acknowledge and agree that you understand its entertainment-only nature and accept full responsibility for any decisions you make independently of the Service.

4. Eligibility

To use the Service, you must:

  • Be at least 18 years of age.
  • Not be located in a jurisdiction where use of the Service would be unlawful.
  • Not be listed on any government list of prohibited or restricted parties.

If you use the Service on behalf of another person or entity, you represent that you are authorised to accept these Terms on their behalf, and both you and the person or entity agree to be responsible for compliance with these Terms.

5. User Accounts

If the Service offers account registration, you agree to provide accurate, current, and complete information during the registration process and to update this information promptly if it changes. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account.

You must not share your account credentials with others, and you must notify us immediately if you suspect any unauthorised access to your account. We are not responsible for any loss or damage arising from your failure to maintain the security of your account.

We reserve the right to suspend, disable, or delete your account at our sole discretion, including if we reasonably believe you have violated these Terms. We may also reclaim usernames on behalf of individuals or businesses with legal rights, such as trademark ownership.

10. AI-Generated Content Disclaimer

The personality profiles, archetype descriptions, roasts, predictions, and all other text generated by the Service are created by artificial intelligence and are intended solely for entertainment.

We do not guarantee the availability of AI-Generated Content. If the AI service is unavailable, the Service may display generic archetype content in place of personalised copy.

11. Sharing and Social Features

The Service allows you to share your Persona Card via social media, direct links, and downloadable images. When you share a Persona Card, the content of the card (including archetype, statistics, commentary, and the associated wallet address) becomes publicly accessible via the shared URL or image.

You are solely responsible for any content you share through or in connection with the Service, including any commentary you add when posting on social media. You agree not to use shared Persona Cards to harass, defame, or mislead others.

Wallet addresses submitted to the Service are public blockchain addresses. By revealing a wallet address and sharing the resulting Persona Card, you acknowledge that the wallet address and associated card content will be publicly visible.

12. Rate Limiting and Access Controls

To protect the Service and ensure fair usage, we implement rate limits on the number of reveals and requests that can be made within a given time period. Exceeding these limits may result in temporary or permanent restriction of your access to the Service.

We reserve the right to modify rate limits, block access, or restrict usage at any time and without prior notice if we reasonably believe such action is necessary to protect the Service or its users.

13. Territories and Restrictions

Vtail Ltd is a UK-based company and is required to comply with UK sanctions law (administered by OFSI), UN Security Council sanctions, and applicable anti-money laundering regulations. We may restrict access to the Service from certain countries or territories at any time in order to comply with applicable laws, sanctions, or for fraud prevention purposes.

You are responsible for ensuring that your use of the Service is lawful in your jurisdiction. Access to the Service from territories where such access is prohibited is at your own risk and responsibility.

14. Disclaimer of Warranties

THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, VTAIL LTD DISCLAIMS ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY.

These limitations apply even if we have been advised of the possibility of such damages and even if a remedy set forth in these Terms is found to have failed its essential purpose.
