Provenance · x402
A programmable provenance layer for physical art. Collectors pay 0.05 USDC to verify a painting's high-res authenticity history or 'dip' into a painter’s process reel. Artists meter access to private viewing rooms and high-fidelity source files, turning the traditional portfolio into a per-view economy. Each view returns a Hedera transaction id, cryptographically linking the interest to the asset.
The primitive.
Access to the painting portfolios engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveShifts the portfolio from a static resume to a metered discovery engine. By charging micro-fees for verifiable history, it filters for high-intent collectors and provides immediate micropayment liquidity to artists for their digital 'footprint' without requiring a full NFT sale.
