KYC documents for sellers vs bidders

Bidder KYC (buyer identity)

Bidders submit government-issued photo ID (passport or driver's licence) and optionally proof of address. This unlocks Verified tier bid limits.

Seller KYC (business / ACH payouts)

Sellers must also verify identity to receive ACH / bank payouts via Stripe Connect. Upload at /account/verification or /account/seller/kyc.
