Terms of Service

1. Introduction

These Terms of Service (“Terms”) govern your access to and use of:

• blocksightlabs.com
• portal.blocksight.dev
• any BlockSight APIs, dashboards, software, documentation, reports and related services (collectively, the Services).

The Services are provided by Smart Software Services B.V. (“BlockSight”, “we”, “our” or “us”).

By accessing or using the Services, you agree to be bound by these Terms.

If you do not agree, you must not use the Services.

2. Eligibility

You must:

• be at least 18 years old;
• have legal capacity to enter into contracts;
• if acting on behalf of an organisation, have authority to bind that organisation;
• comply with all applicable laws and regulations.

You are responsible for maintaining the confidentiality of your account credentials and for all activity occurring under your account.

3. Description of the Services

BlockSight provides blockchain intelligence software designed to assist users in understanding blockchain activity and associated risks.

Services may include:

• wallet analysis;
• transaction analysis;
• entity identification;
• behavioural profiling;
• sanctions screening;
• fraud detection;
• risk scoring;
• predictive analytics;
• machine learning models;
• reporting;
• APIs;
• investigative tooling.

The Services may evolve over time. We may introduce, modify or remove features at any time.

4. Nature of BlockSight’s outputs

The Services generate analytical outputs designed to assist human decision-making.

These outputs may include:

• statistical analyses;
• behavioural assessments;
• predictive models;
• heuristic classifications;
• confidence scores;
• entity attributions;
• risk indicators.

Unless expressly stated otherwise, these outputs represent probabilistic analytical opinions rather than verified facts.

Risk scores represent an estimate of the likelihood of certain characteristics or behaviours based on available information and model outputs.

No output should be interpreted as conclusive evidence that a wallet, transaction or entity:

• is fraudulent;
• has engaged in criminal conduct;
• is controlled by a particular individual or organisation;
• violates sanctions;
• presents no risk.

5. Sources of information

Our analyses may incorporate information from multiple sources, including:

• public blockchain networks;
• open-source intelligence;
• publicly available records;
• commercial data providers;
• customer-provided information;
• internally generated datasets;
• machine learning models developed by BlockSight.

We perform quality assurance and continuously improve our data pipelines.

However, neither blockchain data nor third-party information is guaranteed to be complete, accurate or current.

New information may materially change previous analyses.

6. Continuous model evolution

Blockchain intelligence is inherently dynamic.

Our models, heuristics and datasets evolve continuously as:

• new blockchain activity occurs;
• additional intelligence becomes available;
• attribution improves;
• false positives are corrected;
• false negatives are discovered;
• machine learning models are retrained;
• behavioural models are refined.

Accordingly:

• historical reports may differ from current reports;
• risk scores may increase or decrease;
• classifications may change;
• confidence levels may change.

Such changes do not necessarily indicate that earlier analyses were incorrect.

7. Customer responsibilities

You remain solely responsible for:

• evaluating information produced by the Services;
• verifying conclusions before taking action;
• complying with applicable laws;
• exercising appropriate professional judgement.

You should not rely solely upon BlockSight outputs when making legal, financial, investment, regulatory or enforcement decisions.

8. No professional advice

The Services do not constitute:

• legal advice;
• financial advice;
• investment advice;
• accounting advice;
• tax advice;
• regulatory advice;
• compliance advice.

Nothing within the Services creates a solicitor-client, fiduciary or professional advisory relationship.

Independent professional advice should be obtained where appropriate.

9. Regulatory responsibility

BlockSight is an analytical platform.

Customers remain solely responsible for satisfying their own legal and regulatory obligations, including, where applicable:

• Anti-Money Laundering (AML);
• Counter-Terrorist Financing (CTF);
• Know Your Customer (KYC);
• sanctions compliance;
• suspicious activity reporting;
• financial crime investigations.

Use of the Services does not itself satisfy any statutory or regulatory requirement.

10. No warranty of accuracy

To the maximum extent permitted by law, BlockSight does not warrant that:

• any score is accurate;
• any entity attribution is correct;
• any prediction will prove correct;
• all malicious behaviour will be detected;
• all legitimate behaviour will be recognised;
• any blockchain address belongs to a particular person;
• all information is complete.

The absence of a risk indicator does not imply safety.

The presence of a risk indicator does not establish wrongdoing.

11. Investigation and enforcement

BlockSight is an intelligence and analytical platform intended to support investigations and risk assessment.

The Services are designed to assist users in identifying potential areas of concern, prioritising investigative effort and informing professional judgement. They are not intended to replace appropriate human review, due diligence or independent verification.

Before taking material action based on BlockSight outputs, including but not limited to:

• freezing or restricting assets;
• blocking or terminating customer accounts;
• filing Suspicious Activity Reports (SARs) or equivalent regulatory reports;
• reporting individuals or organisations to law enforcement or regulators;
• initiating legal proceedings;
• declining or terminating commercial relationships;

you are responsible for conducting your own investigation and corroborating relevant findings using appropriate evidence and procedures.

BlockSight does not determine whether any person or entity has engaged in unlawful conduct, nor does it make regulatory or enforcement decisions on behalf of its users.

You remain solely responsible for all decisions, actions and omissions arising from your use of the Services.

12. Fairness and intended use

BlockSight analyses blockchain activity.

Our models are not designed to infer, predict or classify protected personal characteristics such as race, religion, ethnicity, political opinion, sexual orientation or other protected attributes.
