KYC: who checks what

Verification happens in layers, and each layer checks something specific. Identity verification confirms who you are - an individual with government ID, or a business with its registration and beneficial owners. Sanctions screening checks you against watchlists. Bank-account verification checks that a payout account genuinely belongs to you.

Each layer unlocks a little more: browsing needs nothing, buying needs a verified identity, and financing needs full business verification. You are only ever asked for what the next step actually requires.
