Chromatix · x402

A hyper-granular digital palette where color is equity. Users pay $0.01 USDC to 'claim' a specific Hex/RGB coordinate, minting a transient chromatic asset. Every time another creator uses your protected color code in a generative canvas or spatial environment, a micro-royalty is settled on-chain. It transforms color theory into a liquid, metered economy.

The primitive.

full primer →

Access to the chromatic art NFTs 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 primitiveBy commoditizing the individual pixel/color coordinate via x402, we shift from selling 'finished' art to selling the atomic components of art. It creates a 'Proof of Pigment' protocol where every interaction with a specific hue is a metered event.
