TruePigment · Paid Certificate

Prove the provenance of every pigment. This turns transparency from a static claim into a verifiable micropayment event, allowing collectors to 'audit' an artwork's physical composition for cents. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.

The primitive.

One 0.01 USDC payment turns the supply chain transparency record into a signed certificate painters can email, attach or archive — and the page proves who signed it without asking anyone to trust the server.

Kernel
a 0.01 USDC payment over x402 that returns a relayer-signed provenance certificate over the WOTS+ head — a portable document anyone can verify without trusting the issuer
Drives the UI as
a certificate card with the signed fields, the issuing signer, and a 'recover signer' check that runs in the browser

A high-frequency licensing gateway where digital assets are metered by the millisecond. Each glance or API call triggers an EIP-3009 transfer, returning a Base tx hash as a cryptographically verifiable proof-of-usage. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
programmable artwork framing
BORDERLINE · Paid Certificate
A programmable border-engine where every aesthetic shift is a transaction. Use the QUIP primitive to meter 'Gaze-Based Evolution' (auto-shifting frames based on how many wall-clocks pass) or 'Oracle-Linked Skins' (weather/price/time-of-day) where each asset state-change is a paid, verifiable event. Pay to re-frame your collection for a specific gallery mood. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
