How this service works
Check up to 50 crypto addresses (ETH, BTC, TRX, USDT, SOL and more) against the OFAC SDN list's digital currency addresses: PASS or BLOCK with the sanctioned party and program. Use as a pre-payment AML gate.
Output
For each submitted address, the endpoint returns a PASS or BLOCK verdict. For blocked addresses, it includes the name of the sanctioned party and the specific OFAC program (e.g., UKRAINE-EO13685, CYBER2) associated with the address. Clean addresses receive a simple PASS.
Example use cases
Pre-payment crypto AML gate
“I'm about to send USDC to this Ethereum address — 0xAbCd1234EfGh5678IjKl — can you check it against the OFAC SDN list first and tell me if it's safe to pay?”
Bulk exchange onboarding screen
“We're onboarding new users and need to screen these 20 wallet addresses across BTC, ETH, and SOL for OFAC sanctions before activating their accounts — can you run them all through at once?”
DeFi protocol compliance check
“Our smart contract is about to interact with this Tron address TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t — flag it if it matches any OFAC sanctioned entity or program.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/compliance/sanctions-wallet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call OFAC sanctions screen for crypto addresses across multiple chains (ETH, BTC, TRX, SOL, USDT, etc.) without maintaining your own SDN list integration. Ideal as a pre-payment AML gate in agent workflows processing crypto transactions, or for compliance checks during user onboarding on crypto platforms. Supports batch screening of up to 50 addresses per call, making it efficient for bulk use cases.
Side effects
- Invalid or malformed address format causes rejection
- Exceeding 50 addresses per request returns an error
- Unsupported blockchain network address types may not be recognized
- Network timeout from the hosted render.com service under load
- OFAC SDN list may have a slight update lag vs. the official database
