How this service works
OFAC SDN list digital-currency addresses (from the Remarks field 'Digital Currency Address - <CODE> <address>'): list up to 200 entries with currency code, address and sanctioned entity name, optionally filtered by currency or checked for one address. Covers the current SDN.CSV only; the list is not complete for every chain, and a miss is not proof an address is clean.
Output
Returns a JSON object with: the data source (OFAC SDN.CSV via mirror), a timestamp of when the data was fetched, the total number of sanctioned entries, a list of matched entries each containing entity name, wallet address, and currency code, and an addressCheck field indicating whether a queried address matched any entry. Supports pagination via a limit parameter (1–200, default 20).
Example use cases
Pre-transaction sanctions screening
“Before I send funds, check if the Ethereum wallet 0xAbCd1234 is listed on the OFAC SDN sanctions list — I need to be sure it's not a flagged address.”
Compliance audit of crypto currency list
“Pull the full OFAC-sanctioned wallet list filtered to USDT addresses, up to 100 entries, so I can cross-reference our customer wallets for AML compliance.”
Regulatory dashboard for sanctioned wallets
“Get the latest 50 OFAC-sanctioned crypto wallet entries across all currencies so I can update our sanctions screening dashboard with current data.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/sanctioned-crypto-wallets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to screen cryptocurrency wallet addresses against the OFAC Specially Designated Nationals (SDN) list for compliance, AML, or sanctions enforcement purposes. It is ideal for pre-transaction screening, automated compliance checks, or building regulatory dashboards. Prefer this over general blockchain analytics tools when you specifically need authoritative OFAC SDN data with no signup or API key overhead, and when pay-per-call pricing at $0.002 USDC is preferable to a subscription.
Side effects
- Address not found in SDN list returns addressCheck: null rather than an error
- Stale mirror data may lag behind the latest OFAC SDN publication
- Invalid currency code may return empty results rather than an error
- Limit out of range (below 1 or above 200) may return a validation error
- Payment failure (402) — call is not charged if it fails
