How this service works
Crypto wallet sanctions check (OFAC): is this blockchain address on the US Treasury OFAC sanctions lists? Exact match against all 1,000+ digital currency addresses OFAC publishes on SDN and Consolidated entries (Bitcoin, Tron, Ethereum and EVM chains, USDT, Litecoin, Monero and more), returning the listing's program and entry ID. Use before sending or accepting a crypto payment. No tracing or risk scoring. Signed receipt.
Output
Returns whether the address is OFAC-listed (boolean), any matching SDN or Consolidated list entries (including entity name, OFAC program code, entry UID, currency), the exact-match method used, list publication date and record count, dataset coverage by currency (BTC, ETH, TRX, XMR, USDT, etc.), and a disclaimer notice. Also returns an Ed25519-signed receipt with timestamp, price, and hashes for auditability.
Example use cases
Pre-payment sanctions screening
“I'm about to send USDC to 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 — can you check if that wallet is on the OFAC SDN list before I confirm the transaction?”
Incoming payment compliance check
“A customer just sent us a payment from the Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na — can you verify it's not on any OFAC sanctions list so we can safely accept it?”
Tron address KYC screening
“We need to screen this Tron wallet address TRX7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t against OFAC's sanctions list before onboarding this customer — is it listed?”
Technical details
Endpoint
GEThttps://api.stablecoingateways.com/v1/sanctions/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, definitive, auditable OFAC exact-match check on a specific crypto wallet address before processing or accepting a payment. It covers all 1,000+ digital currency addresses across Bitcoin, Ethereum/EVM, Tron, USDT, Litecoin, Monero and more. Choose this over general compliance APIs when you need a signed receipt for audit trails, want a lightweight point-check without risk scoring or chain tracing, and require low-cost per-call pricing at $0.002 USDC. Not suitable if you need on-chain tracing, exposure scoring, or risk profiling beyond OFAC exact matches.
Side effects
- Invalid or malformed address (too short, too long, or invalid characters) returns a 400 error
- Address not found on any sanctions list returns listed: false with empty matches array (not an error)
- OFAC dataset may lag official publications by hours — loaded_at timestamp indicates freshness
- Only exact address matches are returned; no clustering, tracing, or indirect exposure detection
- Non-standard address formats may not be recognized across all chain types
