OFAC Crypto Address Checker
Paste any crypto wallet address to check it against the OFAC SDN sanctions list, instantly and free. Works for Bitcoin, Ethereum and EVM (0x) chains, and Zcash. No account, no API key, and the address never leaves this check. This is the same OFAC screening Shieldz runs on every payment.
What is an OFAC crypto address checker?
The U.S. Office of Foreign Assets Control (OFAC) publishes the Specially Designated Nationals (SDN) list, and it includes specific cryptocurrency wallet addresses tied to sanctioned people, entities and services. An OFAC crypto address checker looks up a single wallet address against that sanctioned-address list and tells you whether it appears on it. Sending or receiving funds to a sanctioned address can carry serious legal consequences, so screening an address before you transact is a basic, sensible precaution.
How to check if a crypto address is sanctioned
Paste the wallet address into the box above and press check. The tool screens it against the OFAC-derived sanctioned digital-currency address list and returns one of two results in a fraction of a second:
- Clear, the address is not on the OFAC sanctioned-address list.
- Sanctioned, the address matches an entry on the OFAC list. Do not transact with it.
It works for Bitcoin addresses, Ethereum and EVM addresses (the 0x… format shared by Base, Arbitrum, Optimism, Polygon and Ethereum), and Zcash addresses. EVM addresses are matched case-insensitively.
Where the sanctions data comes from
The list is derived directly from the OFAC SDN list and refreshed daily from a public, CI-maintained dataset of sanctioned Bitcoin, Ethereum and Zcash addresses that is widely used across the industry. Shieldz loads it in memory and runs the exact same check on every payment address it processes, so this tool shows you what Shieldz itself sees. If the list has not loaded, the tool tells you rather than returning a false "clear".
Why address screening matters for merchants
If you accept crypto, screening the paying address protects you from unknowingly receiving funds from a sanctioned wallet. A non-custodial crypto payment gateway like Shieldz builds this in: it screens paying and settlement addresses against the OFAC list automatically, on the counterparty, without ever holding your money in an account it could freeze. That is the key difference from custodial processors, where compliance friction lands on your payout instead of on the counterparty. Read the case study on how custody creates AML holds.
Screening is built into every Shieldz payment
You do not have to run this check by hand. Every payment link, tip jar and API invoice is OFAC-screened automatically, and Shieldz only ever sees a public address, so it can screen a counterparty but can never freeze, hold or seize your funds. You can verify that non-custodial design yourself. Accept Bitcoin, USDC, USDT and shielded Zcash, all with $0 platform fee and no KYC to start.
FAQ
Is this OFAC address checker free?
Yes. It is completely free, with no signup and no API key. Paste an address and check it.
Which address types can I check?
Bitcoin, Ethereum and all EVM chains (the 0x… format), and Zcash addresses. EVM addresses are checked case-insensitively.
Does a "clear" result guarantee the address is safe?
No. It means the address is not on the OFAC SDN sanctioned-address list at check time. It is not legal advice and not a substitute for a full compliance program.
Is my address stored or shared?
The check is a simple, rate-limited lookup against an in-memory list. Shieldz screens the address and returns the result; it does not publish it.
How often is the list updated?
The sanctioned-address list is refreshed daily from the OFAC-derived public dataset.
