Crossmint requires certain user identity information from your customers to provide regulated products. The required data varies by product and can be collected through several supported methods. Crossmint supports progressive onboarding, with lighter verification for eligible users up to $1,000 in transaction volume.
KYB or KYC — which do you need?
  • KYB (Know Your Business) verifies your company. You complete it once, with the Crossmint team, before you get production access for the products that require it. See Account Verification.
  • KYC (Know Your Customer), covered on this page, verifies your users. You complete it per product, as shown below.
  • KYB and KYC are separate checks — passing one does not satisfy the other.

FAQs

Crossmint supports Persona and Sumsub as identity verification (IDV) vendors. To use any other vendor, you must get it approved first—raise it with your Customer Success Engineer (CSE).
Token sharing is not yet supported. If this is something you need, reach out to your Customer Success Engineer (CSE).
A hybrid approach is not yet supported. You either run your own identity verification and pass that data to Crossmint, or use Crossmint’s embedded KYC in the checkout.
Not yet. The Create or Update User endpoint accepts identity data for individuals only (name, date of birth, nationality, identity document, and so on) — there is no business or entity user type. Support for business users is coming soon. If your users are companies, reach out to your Customer Success Engineer (CSE).
