Crypto Wallet Risk Check
Paste any Bitcoin or Ethereum address to screen it against the US Treasury OFAC sanctions list and known mixers — and see whether it has transacted with flagged addresses.
Why check a crypto address?
A wallet address is pseudonymous, not anonymous. Before you send funds to a counterparty, accept a payment, or chase stolen crypto, the address itself carries signal: whether it appears on a sanctions list, whether it has interacted with a mixer used to launder funds, and who it moves money with. Sending funds to a sanctioned address can carry legal consequences even if you did not know.
Leads, not verdicts
Blockchain attribution is probabilistic. Clustering heuristics used across the industry can link wallets that merely share a service, and third-party labels can be outdated or overly broad — a well-documented source of false positives in commercial tools. Aletheia shows the source of every label so you can verify it, and presents findings as investigative leads rather than conclusions.
Frequently asked questions
How do I check if a crypto wallet address is sanctioned?
Paste the Bitcoin or Ethereum address into the tool above. Aletheia screens it against the US Treasury OFAC Specially Designated Nationals (SDN) list of sanctioned digital-currency addresses, plus a set of known mixer and burn addresses, and then screens its immediate transaction counterparties.
Is this crypto address check free?
Yes. The wallet risk check is free and requires no signup. It performs a one-hop screen. Multi-hop tracing, mention discovery, continuous monitoring and evidence export are part of the paid Aletheia platform.
What does it mean if my address shows 'no flags found'?
It means no sanctioned or known-mixer address was found on the wallet itself or among its immediate counterparties in this limited one-hop check. It is not proof of legitimacy. Attribution findings should always be treated as investigative leads rather than determinations.
Where does the sanctions data come from?
From the US Treasury's OFAC SDN list of digital-currency addresses, refreshed regularly. Every attribution in the result shows its source, so you can independently verify any label rather than trusting an unexplained score.
Can I trace where the stolen funds went?
The free check shows flagged immediate counterparties. Full multi-hop tracing — following funds through intermediaries until they reach an exchange or mixer — is available in the Aletheia platform, along with a court-ready evidence report.
Also free: check what your domain exposes to attackers.
