Scanning

Paycrest runs a series of checks against transactions they send to their escrow contract. These checks include verifying the addresses involved are not sanctioned by OFAC, using data gathered by Shield3 and Chainalysis. Addresses are also verified against the database of labelled addresses provided by Forta's scam detector.

Monitoring & Reporting

Paycrest uses Shield3 to monitor the activity on their smart contracts, and receive alerts whenever something is awry. Lastly, reporting is a crucial component of remaining compliant. Using Shield3's UI, Paycrest easily generates the reports they need.
