Enhanced Due Diligence (EDD) is an extra verification step required under AML and CFT regulations. It confirms that a user’s activity, source of funds, and transaction purpose are legitimate. EDD reviews usually complete in 24 to 48 hours. For the API calls, limits and statuses, see Limits and EDD. The purpose values in POST /payin/edd/save match the rows in the table below.

When EDD is triggered

EDD can be triggered for both Onramp (Payin) or Offramp (Payout) flows when any of the following occur:
  • A transaction volume threshold is reached
  • A suspicious activity or red flag indicator is detected
  • The user asks for a higher daily limit

Documents required for EDD

The documents required depend on the declared purpose of the user’s crypto activities.

EDD failure reasons

Under the “Prohibition of Tipping Off” clause in FIU India’s AML/CFT guidelines, we may not be able to share exact reasons for EDD failures. Disclosing specific reasons could allow users to manipulate documents or responses to bypass compliance checks.
