Frequently asked questions
Is the wallet check really free?
Yes. Checking a BTC, ETH or USDT (ERC20/TRC20) address against our sanctions and ransomware databases is free and doesn't require signing up. A business API with higher limits is available for exchanges.
What data sources do you check against?
Sources include OFAC, UK, UN, EU, Ransomwhere, Scam Sniffer, Tether/Circle, OpenSanctions and the live Chainalysis oracle for Ethereum. Sources can overlap. Results show applicability, availability and freshness. The operator confirmed permission to use OpenSanctions.
What does "indirect exposure" mean?
The address interacted with a labeled counterparty directly or through an intermediary. Percentages use separate denominators per asset in the latest history page; an intermediary link does not prove a transfer of funds.
Which cryptocurrencies and networks are supported?
Bitcoin, Ethereum, USDT-ERC20, USDC-ERC20 and USDT-TRC20 are supported. No release date for additional networks is announced: reliable free sources and a validated method come first.
