sanctions — OFAC SDN address screening
OFAC SDN exact-address screening for crypto addresses across every chain in the US Treasury sdn_advanced.xml snapshot ('Digital Currency Address' entries; ~974 addresses). A 'clean' verdict means ONLY that the exact address is not present in the OFAC SDN snapshot — it is NOT a safety clearance: the service runs no heuristic, malicious-address, or on-chain behavioural analysis, and absence of a match is negative evidence, not proof a counterparty is safe.
