How it works
- Run initial verification: Your company runs or identifies existing KYC, ID verification, and liveness checks with your own IDV provider (such as Persona or Sumsub)
- Pass KYC data to Crossmint: Share that KYC data with Crossmint via API so that regulated actions (onramp, offramp, payouts) can leverage that existing KYC data
- Crossmint handles additional screening: Crossmint runs sanction and PEP (Politically Exposed Persons) screens, and performs ongoing monitoring to ensure compliance
If your company has not provided all required information, users will be prompted to provide it client-side when initiating a regulated activity, as it’s done with Crossmint Onramp.
Data Requirements Vary
The information required for each user depends on the country and the activity type:- Payouts: Basic user details for payouts
- Onramp/Offramp: Additional user information
