OFAC-sanctioned crypto addresses, by chain

OFAC publishes digital-currency addresses as fields on SDN entries. As of 2026-07-24 there are 963 of them across 19 chains, belonging to 91 designated persons. Every address is listed on the chain pages below.

Addresses by chain

OFAC also publishes one or two addresses each on Arbitrum, BNB Smart Chain, Bitcoin SV, Bitcoin Gold, Dogecoin, Ethereum Classic, USD Coin (USDC), XRP Ledger, Verge. Those are included in the API's matching set but do not have their own page — a page for a single address would say nothing this table does not.

What a sanctioned address actually obliges you to do

An address on this list is the property of a blocked person. For a U.S. person, dealing in it is prohibited and the property must be blocked and reported to OFAC, generally within 10 business days. OFAC applies strict liability, so a transfer made without knowing the address was listed is still a violation. Non-U.S. persons face secondary sanctions exposure rather than direct liability. None of this is legal advice.

The practical consequence for anything automated is that screening has to happen before the transaction is signed, against a list fetched now rather than a copy taken at build time.

Screen this programmatically

The same data behind this page is available as a single unauthenticated GET. It checks an address against every digital-currency address on the SDN list, and returns a match list rather than a yes/no so you can log what matched and why:

curl "https://sanctionsai.dev/sanctions?wallet=TNiq9AXBp9EjUqhDhrwrfvAA8U3GUQZH81"

The free tier allows 5 checks per day with no signup, which is enough to wire the call up and see the response shape. Production limits and the audit log are on the paid tiers; the API reference covers batch screening and the degraded flag you should alert on.
