THE W4CHECK SERVICE, INCLUDING THE @W4CHECK_BOT TELEGRAM BOT, WEBSITE, AND ALL REPORTS GENERATED ("SERVICE"), IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT ANY WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. WE EXPRESSLY DISCLAIM ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, RELIABILITY, AVAILABILITY, AND NON-INFRINGEMENT.

No Guarantee of Accuracy

The information and reports provided by the Service are for informational purposes only. We do not guarantee the accuracy, completeness, timeliness, or reliability of any data, analysis, or results provided. Sanctions data may not reflect the most recent government updates. Risk intelligence data is sourced from third parties and may contain errors, omissions, or inaccuracies. Behavioral analysis is algorithmic and may produce false positives or false negatives.

Not Legal, Financial, or Compliance Advice

Nothing provided by the Service constitutes legal advice, financial advice, regulatory guidance, or a complete compliance program. The Service is a screening assistance tool and does not replace professional legal or compliance counsel. Any decisions made based on information provided by the Service are made at your own risk.

No Responsibility for Decisions

We accept no responsibility for any decisions you make, actions you take, or consequences that arise from using the Service or relying on its output. This includes, without limitation, decisions to approve or reject transactions, onboard or offboard clients, file or not file suspicious activity reports, or any other compliance or business decisions.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, W4CHECK AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE SERVICE, INCLUDING BUT NOT LIMITED TO:

Third-Party Data

The Service incorporates data from third-party sources including government sanctions lists, blockchain infrastructure providers, and risk intelligence services. We are not responsible for the accuracy, availability, or reliability of third-party data. Third-party data providers may change their data, APIs, or terms at any time without notice to us.

Service Availability

We do not guarantee that the Service will be available at all times. The Service may be interrupted, suspended, or discontinued at any time without notice. We are not liable for any losses arising from service unavailability.

Blockchain Data Limitations

Behavioral analysis is performed on publicly available blockchain transaction data. This analysis has inherent limitations including but not limited to: inability to identify off-chain transactions, inability to verify the identity of wallet owners, limited transaction history (analysis covers the most recent operations only), and the possibility that normal transaction patterns may be flagged or that suspicious patterns may be missed.

Your Responsibility

You are solely responsible for your own compliance obligations under applicable laws and regulations. You should not rely on this Service as your sole compliance measure. You are responsible for conducting your own due diligence and for engaging qualified compliance and legal professionals.
