# Data Sources and Storage Our assessments combine **on-chain, off-chain, and risk analysis data**. ### Data Sources * **On-chain data** * Contract events, calls, balances, transfers * Historical behaviour (e.g., exploits, depegs, slashing events) * **Off-chain disclosures** * Audit reports and security reviews * Whitepapers, docs, governance forums, legal disclosures * **Proprietary heuristics** * Signals, derived from on-chain events and enriched with off-chain classification and machine learning models * **Direct protocol information** * Where data is not publicly available, we may request additional information from protocol teams, if necessary under **NDA** * For compliance, we run **KYB and sanctions checks** via an external provider where relevant ### Storage and Documentation * Each **rating question** is answered by the analyst and documented with sources, proof, and reasoning in an internal, secure data storage. * Where possible, **sources and proofs are cited** in the risk reports and fact sheets so that users can trace back the rationale. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
