🎨 Visual Art · tokenized generative art

LUMINA · x402

A micro-curation protocol where viewers pay $0.01 per minute to 'illuminate' generative art manifests. High-fidelity rendering isn't free; users stream micropayments to keep the art alive on-chain. Artists receive continuous revenue based on dwell time rather than single-sale speculation. Every 'Heartbeat' event is a 0.01 USDC transaction returned with a Hedera transaction id, proving the artwork was rendered for a specific viewer in real-time.

The primitive.

full primer →

Access to the tokenized generative art 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 primitiveTraditional NFT galleries are static; x402 turns display into a metered utility. By requiring a micropayment to trigger the generative seed and maintain the render, the app creates a direct value link between attention and compute, making the 'view' a programmable economic event.
