FLIPBOOK · Pay to Anchor

Instead of static NFTs, collectors pay to 'flip' through the creative process in real-time. Each stroke sequence is gated by an EIP-3009 signature, allowing fans to micro-fund the labor-intensive act of hand-drawn animation as it happens. Payment settles the frame to the ledger, turning 'process' into a metered asset. One 0.01 USDC payment over x402 anchors the WOTS+ seal on-chain — no subscription, no account.

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

Why this primitiveLoading details…

Kernel
a 0.01 USDC payment over x402 on Base Sepolia that buys one on-chain anchor — the server verifies the settlement, then a relayer writes the user's WOTS+ seal into the QUIP verifier on the host chain
Drives the UI as
a numbered payment log running from 402 challenge to settled USDC to the host-chain anchor tx, every hash a clickable explorer link
