OFAC crypto sanctions check
Check whether a crypto address is designated on the U.S. Treasury OFAC SDN list. We track 991 sanctioned addresses across 8 chains, each with the entity name and sanctions programme.
Free, no signup. We never ask for keys, seed phrases, or a connected wallet. Read-only.
A sanctions hit is not the same as a freeze
A stablecoin freeze is an issuer locking tokens on a contract. An OFAC designation is a government naming a person or organisation, and it reaches every chain at once — including Bitcoin, where nobody can freeze anything.
That difference matters for what you do about it. Frozen tokens are a loss. A sanctioned counterparty is a legal exposure that does not go away because the transfer succeeded.
Coverage, and how we keep it honest
We ingest the OFAC SDN list directly from the Treasury's own publication service, daily. The full address set is verified against Treasury's own export — not sampled, not approximated.
A partial feed is more dangerous than an empty one: an empty response is obvious, while a half-response looks healthy and quietly drops whatever is missing. So the ingester alerts if the active count falls below a floor, or if a single run would deactivate an unusual number of addresses.
Crypto designations are rare events. Most publications add none at all, which is exactly why a silent gap would otherwise go unnoticed for months.
What we can tell you about a sanctioned address
- Entity
- The named person or organisation the address is attributed to.
- Programme
- The sanctions programme under which it was designated.
- Chain
- Bitcoin, Ethereum, TRON, XRP, Litecoin, Dash, Zcash and others.
- Recorded events
- Where the address is also on a stablecoin blacklist, the dated on-chain events and their transaction hashes.
What we will not tell you
- We do not publish a probability that any wallet will be sanctioned or frozen. We report exposure that exists, never odds we cannot stand behind.
- A failed check is never reported as clean. If we could not reach the chain, we say so.
- An exchange is not judged by its customers. A public hot wallet deals with everyone, so counterparty risk says nothing about it.
This is an information tool built on public data. It is not a sanctions-compliance programme and it is not legal advice.
Freezes we recorded, as they happened
Straight from our monitor. Median detection is about 6.5 seconds from the on-chain event.

Screen counterparties as a matter of routine
The bot checks sanctions and stablecoin status together, follows the money two and three hops out, and produces a PDF you can hand to a compliance officer or attach to a dispute.
No wallet connection. No keys. Read-only, always.
