A regulatory process to verify the identity of clients to prevent fraud and comply with legal standards.
Know Your Customer (KYC) is a regulatory process used by financial institutions and crypto exchanges to verify the identity of their users. KYC helps prevent fraud, money laundering, and illicit activity by ensuring customers are who they claim to be.
It is a core component of global compliance standards (AML/CFT).
What KYC Typically Requires
Users may be asked to provide:
Full legal name
Date of birth
Residential address
Government-issued ID (passport, driver’s license)
Proof of address (utility bill, bank statement)
Sometimes biometric verification (selfie or video)
Higher account tiers or large transactions require enhanced verification.
Why KYC Is Important
Prevents financial crimes
Protects users from identity fraud
Required for regulatory compliance
Enables fiat on-ramps and off-ramps
Helps exchanges operate legally in multiple jurisdictions
KYC requirements vary widely by region and platform.
KYC in Crypto
Centralized exchanges (CEXs), certain DeFi gateways, and institutional services require KYC. Decentralized protocols often avoid KYC because they operate permissionlessly, though regulation may evolve.
Summary
KYC is a mandatory identity-verification process that helps exchanges and financial institutions comply with regulations and prevent fraud.
