How this service works
Use when an agent must check a crypto wallet against the digital currency addresses on the U.S. Treasury OFAC SDN list before paying or accepting funds. Input: address (EVM matched on every EVM chain; BTC, TRX, SOL...), optional chain. Output: JSON listed yes/no, SDN entry, programs, listed currency and network, OFAC link, list as-of date, data age. Not a legal determination. Example: ?address=0x098B716B8Aaf21512996dC57EB0615e2383E2f96
Output
Returns a JSON object with: a boolean 'hit'/'listed' indicating sanctions status, an array of matches each containing the SDN entry (name, UID, type, programs, countries, OFAC URL, associated digital currency addresses), the query details (address, chain, EVM flag, normalized address), list metadata (source, as-of date, published date, checked-at timestamp, data age in days, entry counts, stale flag), and a disclaimer noting this is not a legal determination.
Example use cases
Pre-payment sanctions screening
“I'm about to send USDC to 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 — can you check that address against the OFAC sanctions list first and tell me if it's flagged, which SDN entry it matches, and which sanctions programs it's under?”
Accepting crypto payment compliance check
“A customer just submitted a payment from the Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf NA — run it through the OFAC SDN list before we accept it and let me know if there's any sanctions hit.”
Solana wallet onboarding screening
“We're onboarding a new user who gave us their Solana wallet address HN7cABqLq46Es1jh92dQQisAq662SmxELLLsHHe4YWrH — screen it against the OFAC SDN list on the solana chain and tell me if it's sanctioned.”
Technical details
Endpoint
GEThttps://1gateway.dev/v1/compliance/sanctions/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or automated system needs a real-time, programmatic OFAC SDN sanctions check on a specific crypto wallet address (EVM, BTC, TRX, SOL, or other chains) before executing or accepting a blockchain payment. It is purpose-built for crypto compliance with multi-chain support, EVM address normalization, and structured JSON output including SDN entry details and list freshness metadata. Prefer it over generic sanctions name-search endpoints when you have a wallet address rather than a person or entity name, and over manual OFAC lookups when you need automated, auditable compliance screening in an agentic payment workflow.
Side effects
- Invalid address format — address does not match expected pattern (returns error)
- Address not found in SDN list — returns listed:false with empty matches array
- Stale list data — list.stale flag set to true with a warning if OFAC data has not refreshed recently
- Unsupported chain value — unrecognized chain parameter may cause unexpected results
- Missing required address parameter — returns 400/validation error
- Service unavailable — upstream OFAC data fetch failure
