In the context of AML/CFT frameworks for cryptoassets, the investigation of transaction histories involves blockchain analysis tools to trace the flow of funds to and from crypto addresses. Specifically, it is essential to assess whether the addresses involved have had prior exposure to illicit activities such as known darknet marketplaces, ransomware payments, or sanctioned entities. This form of "address screening" helps identify potentially tainted cryptoassets.
The DFSA AML Module and associated guidance emphasize that transaction monitoring for cryptoassets requires analyzing the provenance of funds, not just ownership. While identifying the owner is part of customer due diligence (CDD), the transactional exposure itself reveals laundering risks embedded in the chain of transfers.
Extract from DFSA AML Module and COB Module on Crypto Business Rules:
"Transaction monitoring systems must include blockchain analysis to detect suspicious activity related to crypto tokens, including tracing transactions against known illicit sources."
"Enhanced due diligence (EDD) is required when a cryptoasset transaction involves addresses or wallets with a history of illicit activity."
"Risk-based approaches must integrate forensic review of transaction histories to assess financial crime risks in crypto asset transfers"【AML/VER25/05-24: Sections 6.3, 7.3, 13.3; COB/VER45/05-24: Sections 6.13, 15】.
Therefore, assessing the receiving exposure of cryptoasset addresses to illicit activity (Option C) is the most direct and effective method to detect laundering.
