How this service works
Is this address sanctioned? Screens a crypto address against the US Treasury OFAC SDN list's published digital currency addresses (ETH, USDC, USDT, XBT, SOL, TRX and others): the listed entity, programs and listing date on a match, or not found as of the list date. Adds whether it is a wallet (EOA) or contract on Base, Ethereum, Arbitrum, Optimism or Polygon, or a wallet or program-derived address on Solana. Not legal advice.
Output
Returns whether the address is found on the OFAC SDN list (sanctioned: true/false), matched entity name, OFAC programs, listing date, the currency type matched, plus the account classification (EOA wallet vs contract on EVM chains, or wallet vs program-derived address on Solana). Also includes the date and age of the SDN list copy used.
Example use cases
Pre-transfer sanctions compliance check
“Before I send USDC to 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on Ethereum, can you verify it's not on the OFAC SDN sanctions list and tell me whether it's a regular wallet or a contract?”
Solana wallet due diligence
“I'm about to interact with the Solana address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM — can you screen it against the OFAC SDN list and let me know if it's a wallet or a program-derived address?”
Flagging sanctioned counterparty in a transaction
“A user just tried to deposit from 0x7F367cC41522cE07553e823bf3be79A889debe1B on Arbitrum — run an OFAC sanctions screen on that address and tell me which entity and programs it's linked to if it's a match.”
Technical details
Endpoint
GEThttps://onchaincheck.dev/address/screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.005 USDC) per-address OFAC SDN sanctions screen for crypto addresses across EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon) or Solana, combined with on-chain account type classification. Prefer it over general blockchain explorers when you specifically need OFAC SDN compliance data with entity, program, and listing date details in a single call.
Side effects
- Address format invalid or too short (pattern mismatch) — 400 error
- Chain enum value not recognized — 400 error
- Address not found on SDN list returns result: 'not found' with sanctioned: false (not an error)
- List may be a few days old (listAgeDays field indicates staleness)
- Payment not completed or insufficient USDC — 402 Payment Required
- Endpoint only covers addresses explicitly published by OFAC for digital currencies, not all sanctioned entities
