Understanding KYC in Cryptocurrency

Know Your Customer (KYC) is a foundational component of anti-money laundering (AML) compliance for financial institutions (FIs) and cryptocurrency exchanges. It involves verifying the identity of customers during onboarding to assess their risk profiles and prevent financial crimes.

KYC Compliance Steps for VASPs

Virtual Asset Service Providers (VASPs) follow a structured KYC process:

  2. Document Verification
    Cross-check submitted data with official IDs (passport, driver’s license) and utility bills.
  3. Sanctions Screening
    Screen customers against databases of Politically Exposed Persons (PEPs) and sanctioned individuals.
