PATCHLOCK · Pay to Anchor

Stop buying bulk packs to find one sound. DAW-integrated QUIP plugins allow synth designers to monetize individual presets via EIP-3009. No subscription, no bloated libraries—just a per-click logic that settles on Base, turning every 'Load Preset' action into a micro-royalty for the designer. One 0.01 USDC payment over x402 anchors the WOTS+ seal on-chain — no subscription, no account.

The primitive.

Musicians pay 0.01 USDC once, in-page, and the synth programming 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
