Looking for an OFAC sanctions check on an Optimism address? Optimism shares Ethereum's exact 0x address format, so we cannot reliably tell an Optimism address apart from a real Ethereum address without a Optimism-specific block explorer — an integration this tool does not yet have. Rather than silently label a Optimism address as Ethereum and produce a misleading OFAC sanctions check, we honestly decline it.
Why Optimism isn't checked yet
L'initiative Superchain d'Optimism le connecte à Base et à d'autres chaînes OP Stack. Le risque entre les chaînes peut se propager dans tout l'écosystème Superchain.
Every EVM-compatible chain — BNB Chain, Polygon, Arbitrum, Avalanche, Optimism, and others — shares this exact address format with Ethereum. Format alone can never tell them apart; only a chain-specific block explorer can confirm which network an address is actually active on.
What you can check right now
Bitcoin, Ethereum mainnet, and TRON addresses are fully screened against the OFAC SDN list via the checker above or @cryptoamlscan_bot.
