Output
Returns a JSON object with a `sanctioned` boolean field. If `sanctioned: false`, the address is clean. If sanctioned, the response includes the listed entity name, the asset type (e.g. ETH, BTC, USDT), and the OFAC SDN list publish date. Covers ~20 chains including BTC, ETH, USDT, TRX, XMR, with EVM 0x addresses matched case-insensitively.
Example use cases
Pre-transfer compliance check for DeFi
“I'm about to send USDT to 0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43 — can you screen it against the OFAC sanctions list before I proceed?”
Screening incoming Bitcoin payment
“Someone just sent us a payment from bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — can you check if that Bitcoin address is on any US Treasury sanctions lists?”
Automated compliance gate for crypto exchange
“Run a sanctions check on this Tron address TQn9Y2khEsLJW1ChVWFMSMeRDow5KcbLSE — we need to know if it's flagged as an SDN before we allow the withdrawal.”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/sanctions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, per-address OFAC SDN sanctions screening before executing a crypto transaction across any of ~20 supported chains. It is ideal for compliance workflows, DeFi applications, exchanges, or any agent that must verify a counterparty wallet is not a Specially Designated National. Prefer this over manual OFAC lookups or general AML services when you need a simple sanctioned/not-sanctioned answer with entity metadata, at low cost per call, with no third-party risk scoring involved.
Side effects
- Address string too short or malformed — returns validation error
- Address format not recognized for supported chains
- Network timeout reaching OFAC data source
- Address on unsupported chain returns no match (not an error, but may be a false negative)
- Rate limiting if excessive calls are made without payment
