The Office of Foreign Assets Control (OFAC) maintains a Specially Designated Nationals (SDN) list that includes cryptocurrency wallet addresses. Transacting with an OFAC-sanctioned Optimism 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.
Optimism's Superchain initiative connects it to Base and other OP Stack chains. Cross-chain risk can propagate across the entire Superchain ecosystem.
OFAC sanctions and Optimism wallets
OFAC regularly adds OP wallet addresses linked to: terrorist financing, ransomware operators (REvil, Conti, DarkSide), North Korean hacking groups (Lazarus Group), Iranian financial institutions, and Russian sanctioned entities. Like all EVM Layer 2s, Optimism shares address formats with Ethereum. Bridge activity can transfer AML risk from Ethereum mainnet to Optimism and vice versa.
