Sanctioned Address
A sanctioned address is a wallet formally designated by a government body — most commonly OFAC in the United States — as blocked property, meaning it is illegal for U.S. persons to transact with it. It is the highest-severity label FreezeRadar assigns.

What it means
Sanctions designations are legal instruments, not technical ones. A government agency publishes a specific wallet address as part of a broader designation — against an individual, an entity, or a whole service like a mixer — and that publication itself creates legal exposure for anyone who knowingly transacts with the address afterward, regardless of what blockchain it sits on.
Because the designation is public and address-specific, it is directly and unambiguously checkable: a wallet either appears on a current sanctions list or it does not. This makes it one of the few risk categories that carries formal legal consequence rather than being a probabilistic or reputational judgment, which is why FreezeRadar treats a direct sanctions match as its most severe finding.
Real-world example
OFAC's SDN list has included specific wallet addresses tied to Lazarus Group hacks, the Tornado Cash mixer, and various ransomware operators — each addition is a legally binding designation, not a private company's internal risk assessment.

A direct match against a sanctions list is FreezeRadar's highest-severity finding, and it also drives our indirect-exposure checks for wallets that transacted with a sanctioned address one or two hops away.
