# AML Security > Free AML risk screening for USDT and other crypto addresses. Paste an address, > get a sanctions check, a two-hop counterparty trace, and a timestamped PDF report. ## What it does AML Security screens a blockchain address against the OFAC SDN crypto-address list and other consolidated sanctions sets, then traces the addresses that sent funds into it, two hops back, screening each one. Output is a risk index (0–100), a verdict band (clear / caution / flagged), and a downloadable PDF. Supported: USDT on Tron (TRC20), Ethereum (ERC20) and BNB Chain (BEP20); native BTC, ETH and TRX addresses. Network is detected from the address format. Timing: sanctions-only check ~2 seconds. Deep two-hop trace 20–40 seconds, because each counterparty is retrieved from public chain APIs and screened individually. ## Best suited for - P2P sellers, before releasing fiat or goods against USDT that has already landed - Freelancers and merchants, before depositing a client's payment to an exchange - OTC desks, before quoting a counterparty - Anyone needing a dated written record of what was known at the time of a trade Not suited for: recovering or unfreezing your own blocked funds. No screening service can do that. ## Three distinctions the site explains - Block explorer vs AML check: an explorer shows what happened; a screening shows whether the history behind it should change your decision. - Direct vs indirect exposure: direct means the sending address itself touched a sanctioned entity, mixer or fraud wallet; indirect means funds passed through intermediaries first, and the signal weakens with every hop. - Quick vs deep scan: quick is two exact lookups in about three seconds; deep adds two hops of counterparty tracing and takes 20-40 seconds. ## What it explicitly is not - Not a certificate of clean funds, and not legal or financial advice - Not able to freeze or unfreeze USDT. Only Tether Limited can do that, at law enforcement request. Any service claiming an AML check will release frozen funds is running a known scam. - Not a licensed compliance provider ## Key pages - Home and checker: https://amlsecurity.financial/ - What the check covers: https://amlsecurity.financial/#coverage - Method and timing: https://amlsecurity.financial/#how - Report contents: https://amlsecurity.financial/#report - FAQ: https://amlsecurity.financial/#faq ## Data sources US Treasury OFAC SDN list (sanctioned digital currency addresses); EU and UK consolidated lists where addresses are published; TronGrid and Etherscan public APIs for transaction data; optional commercial analytics providers where the operator has connected one.
