KYB, or Know Your Business, is a due diligence process used to verify the legitimacy and identity of a company or organization before it can access financial services. It ensures that businesses operate legally and that their activities comply with regulations designed to prevent fraud, money laundering, and other financial crimes.

The KYB process typically involves confirming a company’s legal registration, address, ownership structure, and ultimate beneficial owners (UBOs). This helps financial institutions and platforms understand who controls the business and how it operates.
