The Office of Foreign Assets Control (OFAC) maintains a Specially Designated Nationals (SDN) list that includes cryptocurrency wallet addresses. Transacting with an OFAC-sanctioned Cosmos address can result in serious legal and financial consequences.
What is the OFAC SDN list?
The OFAC SDN list is maintained by the US Treasury Department and includes individuals, organizations, and cryptocurrency addresses that Americans are prohibited from transacting with. Violations can result in fines up to $1M per transaction and criminal prosecution.
Cosmos addresses are chain-specific despite sharing the same bech32 format. A 'cosmos1' address is for the Cosmos Hub; other chains use different prefixes (osmo1, juno1, etc.).
OFAC sanctions and Cosmos wallets
OFAC regularly adds ATOM wallet addresses linked to: terrorist financing, ransomware operators (REvil, Conti, DarkSide), North Korean hacking groups (Lazarus Group), Iranian financial institutions, and Russian sanctioned entities. IBC (Inter-Blockchain Communication) transfers between Cosmos chains can be used to obscure fund origins. Cross-chain IBC routing is tracked in comprehensive AML analysis.
