Streamline your compliance efforts with 0xProtect: a smart contract registry designed to aid Ethereum block production stakeholders with transaction filtering.

0xProtect maintains an on-chain copy of the OFAC sanctions list, allowing stakeholders such as MEV searchers, block builders, relays and validators, to automatically filter out transactions where sanctioned wallet addresses are present.

How it works

Through the use of a smart contract and intermediary app (Sanctions List Service or SLS), 0xProtect makes filtering requirements available on a common platform, with data stored as a smart contract.

The contract receives updates as relevant changes are detected in the OFAC Sanctions List, meaning stakeholders can have a common understanding of each other's requirements.

Apps and stakeholders can connect directly to the 0xProtect smart contract to automate OFAC checks on every single transaction they process.
