How this service works
Screen an EVM address against the US OFAC SDN digital-currency address list at $0.001 — the cheapest sanctions lookup in the ecosystem, Ed25519-signed so you can verify it offline. Exact-list-match, refreshed daily. Screens that one list only — not EU, UN or UK/OFSI — and a non-match is not evidence the counterparty is legitimate. Not a regulated AML/KYT service and does not discharge any legal screening obligation.
Output
Returns a signed JSON response indicating whether the queried EVM address matched the OFAC SDN digital-currency address list. The result includes the match status (hit or no-match), the screened address, the list date (refreshed daily), and an Ed25519 signature that allows offline verification of the result's authenticity. A no-match result does not certify the address is legitimate — it only confirms absence from this specific list.
Example use cases
Pre-transfer compliance check
“I'm about to send ETH to 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — can you check that address against the OFAC SDN list before I proceed?”
DeFi protocol counterparty screening
“Our protocol needs to block sanctioned wallets — can you run 0x742d35Cc6634C0532925a3b844Bc454e4438f44e through the OFAC digital currency SDN list right now?”
Automated agent wallet gatekeeping
“My agent is about to interact with wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — screen it against the OFAC sanctions list and tell me if there's a hit before it executes anything.”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/screen/address/:addrWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.001), verifiable OFAC SDN check for a single EVM address before executing an on-chain transaction. The Ed25519-signed response is ideal when you need an auditable proof of screening that can be verified offline. Prefer this over broader AML/KYT services when cost per call matters and OFAC US SDN coverage is sufficient for your use case. Not suitable when EU, UN, or UK/OFSI list coverage is required, or when you need a regulated AML service that discharges legal compliance obligations.
Side effects
- Invalid or malformed EVM address returns a 400 error
- Address not found in list returns a no-match (not an error)
- Daily refresh lag may mean very recently added SDN entries are not yet reflected
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Service downtime could make the endpoint unreachable, returning 5xx errors
- Only screens OFAC SDN digital-currency addresses — EU, UN, UK/OFSI lists not covered
