Is this crypto address sanctioned?
Paste the address into a sanctions check that reads the US Treasury SDN list, which publishes the crypto addresses of designated people and groups. If it is listed, a US person or business must not pay it. If it is not listed, that is true only as of the date the list was read, and it says nothing about where the funds came from.
Sanctions are the one crypto risk that is not a property of the address itself. Nothing on chain marks a wallet as designated: a government decides it and writes it into a list. So the only honest way to answer the question is to read that list, say which list it was and when it was read, and be plain about what a negative does not cover.

Public address only. No wallet connection. Nothing to sign.
Where the answer actually lives
The US Treasury's Office of Foreign Assets Control (OFAC) publishes the Specially Designated Nationals list, known as the SDN list. Since 2018 some entries on it carry digital currency addresses, published per asset: a designated group might have Bitcoin, Ethereum, USDT and Tron addresses listed against its name. That list is the authoritative source for the question most people mean when they ask whether an address is sanctioned. A designation is a legal act recorded in a document, so no chain analysis, score or heuristic can produce it. A tool either reads the list or it is guessing.
How to check in a few seconds
Our Sanctions Check reads a daily mirror of the SDN list and answers for EVM chains, Bitcoin, Solana and Tron. It needs no wallet connection and no signature, because reading a public list does not require access to anything you own. A positive result names the list it came from. A negative result carries the date the list was last refreshed, because not listed is only ever true as of a date. If a site asks you to connect a wallet to run a sanctions check, treat that as the warning sign.
What a listing means for you
For a US person or business, sending funds to a listed address is a sanctions violation, whatever the reason for the payment and whether or not you knew. Receiving from one is also a problem, because the funds are blocked property. Outside the US the obligations depend on where you are and which lists apply to you, and many exchanges apply the SDN list globally regardless. If an address you are about to pay is listed, do not pay it. If you have already received funds from one, talk to a lawyer or your exchange's compliance team before you move them, not after.
What a negative does not tell you
Not on the SDN list means exactly that and nothing more. It does not mean the address is honest, it does not mean the funds are clean, and it does not cover other authorities: the EU, the UK and the UN keep their own lists, and most of them do not publish crypto addresses at all. It also does not follow money. An address can be one hop away from a designated wallet and appear on no list. That is why our check reports a sanctions designation separately from everything else, rather than folding it into a score where a clean number would imply more than the list says.
Sanctioned, frozen and scam are three different answers
People often treat these as one question. They are not. A sanctioned address is designated by a government. A frozen address is one a stablecoin issuer such as Tether or Circle has blacklisted on its own token contract, so tokens sent there can never move again. A scam address is one somebody has reported for drainers, phishing or fraud. An address can be any combination of the three. Before a large payment it is worth asking all three questions, and our Scam Address Checker and USDT Freeze Checker answer the other two.
Why we never turn a designation into a score
A sanctions listing is a fact with a named authority and a date, not a degree of risk. If a tool shows it as a low number on a 0 to 100 scale, the reader is invited to weigh it against other signals, and a designation is not something to weigh. So on Veriql a listed address gets its own label naming the list, never a band and never a number, and the wallet scanner does the same: a designated wallet is reported as sanctioned rather than as a risky one.
FAQ
Which sanctions list does the check use?
The US Treasury OFAC SDN list, through a daily mirror of the digital currency addresses it publishes. We name the list on every positive result and print the refresh date on every negative one. Other authorities keep their own lists and most of them do not publish crypto addresses, so a negative here is a statement about the SDN list only.
How often is the list refreshed?
Once a day, on a schedule. The result always carries the date the list was last read, so you can see how current the answer is rather than having to trust that it is.
Can an address be sanctioned without appearing on the list?
Yes, in effect. Designations name people and groups, and the published addresses are the ones Treasury chose to list. A designated group can control addresses that were never published. Funds can also pass through intermediate wallets that appear on no list. A negative result is therefore a statement about the list, not a clearance of the address.
I received crypto from a sanctioned address. What should I do?
Do not move it and do not try to send it back. Funds from a designated party are generally blocked property for a US person. Speak to a lawyer, or to the compliance team of the exchange where the funds sit, before you act. We can tell you what the list says, but not what your obligations are where you live.
Does the check cover Bitcoin and Tron as well as Ethereum?
Yes. The SDN list publishes addresses per asset rather than per chain, and much of the USDT on it sits on Tron, so a check that only read Ethereum addresses would miss most of what is listed. Ours answers for EVM chains, Bitcoin, Solana and Tron.
