Free AML Check for Crypto: Screen BTC, ETH and USDT-TRC20 Addresses Before You Accept Them

Short answer: XMRList's AML check is a free tool that screens a crypto address or transaction before you accept it, send it on or deposit it to an exchange. Paste a Bitcoin, Ethereum, USDT-TRC20, BNB Chain, Base, Arbitrum, Polygon, Optimism or Litecoin address or transaction ID and it tells you three things: whether anything involved is on the US Treasury OFAC sanctions list, whether Tether or Circle has frozen it, and whether the wallets one step away are flagged. You get a 0 to 100 risk score and a plain recommendation. There is no sign-up, no fee and nothing is stored.

Why screen crypto before you accept it

Crypto is easy to receive and hard to give back. If someone pays you with coins that came from a sanctioned wallet, a hack or a frozen stablecoin address, the problem becomes yours the moment they land. Regulated exchanges screen every deposit, and funds linked to flagged addresses can be frozen while the exchange asks you to explain where they came from. In the worst case, holding or moving funds tied to a sanctioned address can expose you to legal risk.

The people this hits most are not criminals. They are P2P traders, freelancers paid in USDT, small shops that accept crypto, and anyone buying from a stranger on a forum. Paid AML services exist, but most charge per check and ask you to make an account first. A quick free screen catches the most serious problems before they reach you.

What the free AML check looks at

Every check runs the same three tests. The tool lists exactly which of them applied to your result, so you always know what was and wasn't covered.

1. OFAC sanctions list

The Office of Foreign Assets Control, part of the US Treasury, publishes crypto addresses belonging to sanctioned people and groups on its SDN list. The tool matches every address in your check against that list, refreshed daily. As of 4 November 2026 the list holds 1,068 addresses across 18 currencies, including 532 Bitcoin, 266 TRON, 123 Ethereum and 94 USDT addresses. A match is the strongest flag there is, and it scores 100 out of 100.

2. Stablecoin freezes

Tether and Circle can freeze USDT and USDC at any address, and frozen tokens cannot be moved. The tool asks the token contracts directly, live, whether the issuer has blacklisted the address: USDT on Ethereum and TRON, and USDC on Ethereum, Base, Arbitrum, Polygon and Optimism. An address frozen by an issuer scores 85, because exchanges will refuse anything coming from it.

3. Direct (one-hop) exposure

Clean-looking wallets can still receive dirty money. For an address, the tool reads its recent incoming transfers and screens every sender. For a transaction it goes further: it finds the wallets that funded the exact coins being spent and screens those. The result shows how many counterparties are flagged and what share of the value they account for. Exposure to sanctioned or frozen wallets scores between 55 and 95, depending on that share. Exposure to addresses publicly labelled as scams, where the explorer provides such labels (on Ethereum), scores between 30 and 60.

How to run a check, step by step

1. Open the AML check.
2. Paste an address or a transaction ID (TXID, also called the hash). You don't need to say which network it is: the tool recognises 0x… Ethereum-style addresses, T… TRON addresses, bc1…, 1… and 3… Bitcoin addresses, Litecoin addresses and transaction hashes. If a hash could belong to several networks, pick the network from the list.
3. Press Run AML check. Most checks finish in under five seconds. A large Ethereum transaction with many token transfers can take longer.
4. Read the score and the recommendation at the top, then the details: every party with its flags, the exposure table, and the list of checks that ran.
5. Optional: press Create share link to save the report for 30 days and send it to a counterparty or an exchange's support team, or Print / save PDF to keep a copy.

How to read the risk score

The score follows published rules, not a black box. The highest-weighted flag wins: a sanctioned address in the check means 100, whatever else is found.

Address check or transaction check?

They answer different questions. Use an address check before you deal with someone: it tells you whether the wallet itself is sanctioned or frozen and who has been paying it lately. Use a transaction check after you receive a payment: it looks at that one transfer, every party in it, and the wallets that funded those specific coins. A busy P2P trader's wallet may have mixed history while the payment they just sent you came from a clean source, and the transaction check shows that difference.

Which networks are supported

Monero is the exception for a good reason. It hides senders, receivers and amounts by default, so nobody can trace where XMR came from, including us. You can still check whether a Monero address appears on the OFAC list, which currently names 11 XMR addresses. To confirm a Monero payment arrived, use the Monero transaction checker instead.

What it does not check (and why that matters)

Commercial AML firms sell large databases that label exchange wallets, mixers, darknet markets, scams and hacked funds, and they trace funds through many hops. This tool doesn't use paid data and looks only one hop back. That keeps it free and transparent, but it means a low result says "no flags in the public sources we check", not "these funds are clean". An exchange running a commercial tool may see something this check can't. The page says this on every result, and lists the checks that ran and the ones that didn't.

Privacy: what happens to what you paste

• Your address or hash is sent with a form, not in the page address, so it doesn't end up in links, browser history or server access logs.
• The lookups go from our server to public blockchain APIs; your browser never talks to them.
• Results are cached for 10 minutes so a repeat check is instant, then discarded.
• Nothing is saved unless you click Create share link. Shared reports expire after 30 days.
• No account, no email, no tracking scripts. The tool also works through our Tor mirror.

Who it helps

• P2P and OTC traders: screen a buyer's address before releasing coins, and screen the payment after it arrives.
• Merchants and freelancers paid in USDT: check that a customer's payment isn't frozen or tied to a sanctioned wallet before you rely on it.
• Anyone about to deposit to an exchange: see what the exchange's own screening is likely to find first.
• Researchers and journalists: check an address quoted in a news story against the sanctions list, or browse the full list of sanctioned crypto addresses by blockchain.
