Blockchain Analytics

Blockchain analytics is the systematic inspection of on-chain transaction data — wallet addresses, transaction graphs, and token flows — to trace fund movements, cluster related addresses, and detect exposure to sanctioned entities, mixers, or high-risk jurisdictions.

How blockchain analytics supports sanctions compliance

A sanctions check answers "is this specific wallet on the SDN list?" Blockchain analytics answers the harder question: "has this wallet interacted with a sanctioned entity, even indirectly?" It traces the transaction graph to identify indirect exposure that a simple list lookup would miss.

Key techniques

• Address clustering: Grouping wallets controlled by the same entity based on shared inputs, change addresses, and behavioral patterns.
• Transaction graph analysis: Mapping the flow of funds between addresses to identify indirect exposure paths.
• Entity attribution: Linking wallet clusters to known entities (exchanges, mixers, sanctioned groups) using public data and heuristics.
• Risk scoring: Assigning a quantitative risk score based on proximity to sanctioned addresses, mixer interaction, and jurisdictional factors.

SanctionsAI's approach

The SanctionsAI wallet checker combines direct SDN list matching with heuristic risk indicators — mixer interaction, exchange deposit patterns, and jurisdiction flags — to give a fuller picture than a binary sanctioned/not-sanctioned answer.
