Definition
What is KYB (Know Your Business)?
KYB is KYC for companies: confirming that a business legally exists, identifying who owns and controls it (the ultimate beneficial owners, or UBOs) and screening the company and those people against sanctions and adverse lists. Exchanges, payment providers and OTC desks run KYB before onboarding corporate clients and partners.
Overview
Business verification (KYB) for B2B onboarding
When your counterparty is a company, a name is not enough — you also need ownership and related persons. Arya Crypto KYB collects company and UBO data, runs international screening and puts the case in your review queue. The final decision is delivered to your callback, and tokens are deducted on that final state.
Key advantages
- KYB business with a dedicated callback and public code
- Public form link valid for 7 days, or manual submit via API
- Beneficial owners with ownership %, role, nationality and PEP flag
- Risk report, approve/reject review and a completion webhook
