THE VAULT · Pay to Anchor

A design-leak protection layer for luxury accessory patterns. Each payment triggers a cryptographically signed provenance receipt on Base, verifying the viewer’s identity and intent, converting window shoppers into trackable leads. For limited releases, the 100th 'Peep' payment automatically triggers the minting of an exclusivity certificate, closing the vault forever. One 0.01 USDC payment over x402 anchors the WOTS+ seal on-chain — no subscription, no account.

Fashion designers pay 0.01 USDC once, in-page, and the limited-edition accessories seal is written on-chain for them — no funded host-chain wallet, no subscription, just a payment log that ends in a real transaction.
