Free AML check

Is an address or a name on the sanctions list?

In shortPaste a crypto address or type a name, and this free tool checks it against the US Treasury's OFAC sanctions list, the official list that names the crypto addresses of sanctioned people and groups. It runs in your browser, so nothing you type is sent anywhere. No account and no limit.

  • Official OFAC list, read twice a day
  • Every listed crypto address
  • Names and other names
  • No account, no limit

What it checks

Crypto addresses
Every crypto address OFAC lists, on every network and coin it names.
Names
Every person, organisation, ship and aircraft on the list, with the other names OFAC gives for them.
Spelling differences
Names are compared without accents and punctuation, in any word order, and close spellings are shown as possible matches.

What it does not check

  • Other sanctions lists, such as those of the EU, the UK or the UN.
  • Politically exposed persons (PEP) and their relatives.
  • News reports, court records and company registers.
  • Where an address's coins came from or went to. That needs blockchain analysis.

It gives no risk score: it says whether OFAC lists something, and nothing more.

When to use it

A quick first check before you send coins or do business with someone new.

Before a peer-to-peer trade

Check the address a buyer or seller gives you before you send them coins.

Before you pay a new address

An invoice or a payment request from someone you do not know: check the address first.

Checking a company or a person

See whether a business partner or a counterparty appears on the list under any of its names.

Where the list comes from

OFAC, the US Treasury's Office of Foreign Assets Control, publishes the list of Specially Designated Nationals as a file anyone may download. AltoSwap reads that file twice a day and checks against the copy it holds.

Your privacy

The list is loaded into your browser and compared there. The name or address you type is not sent to AltoSwap, to OFAC or to anyone else, and this page runs no analytics.

Questions about the AML check

Is the AML check really free?

Yes. There is no account, no daily limit and no payment. It uses OFAC's public list, which anyone may use.

Which addresses can it check?

Any address on any network. The list names addresses on Bitcoin, Ethereum, Tron, Litecoin, Monero, Solana and other networks, and USDT addresses on several of them. An address of a coin the list does not mention simply has no match.

What should I do if an address is on the list?

Do not send coins to it, and get advice before you accept coins from it. OFAC says US persons are generally prohibited from dealing with anyone on the list, and many exchanges and swap services screen deposits against it.

Does a clear result mean an address is safe?

No. It means OFAC has not listed that address. The list names only a small number of addresses, and an address that has received coins from a listed one is not listed itself. Finding that out takes blockchain analysis, which this tool does not do.

Does AltoSwap check swaps against this list?

The exchanges that carry out AltoSwap swaps run their own screening, and a deposit they flag can be stopped. This page is a separate, free tool that anyone can use, with or without a swap.

How up to date is the list?

OFAC updates the list whenever it adds or removes names. AltoSwap reads it again twice a day, and every result shows the date of the copy it was checked against.

Can I use the result for compliance?

Use it as a first check, not as proof. A business with screening duties needs every list that applies to it, checks on the people involved and records of what was checked. For an official answer, use OFAC's own search.
