🎨 Visual Art · signed digital prints

Imprint · x402

A high-fidelity digital gallery where every 'Right-Click Save' is a paid micro-transaction. Unlock a cryptographically signed, full-resolution master file for 0.01 USDC. Payment triggers an HTS transfer transfer that instantly settles a royalty to the illustrator, returning a Base transaction hash as your permanent proof of patronage. No subscriptions, just a 1-cent toll for high-art provenance.

The primitive.

full primer →

Access to the signed digital prints 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 primitiveMoving away from the 'minting' friction, this reframes digital art as a metered asset. By utilizing x402, we turn the act of viewing or downloading high-quality assets into a seamless micro-payment event, eliminating the need for complex NFT marketplaces for simple attribution and ownership.
