🎨 Visual Art · limited print tracking

Provenance · x402

A high-fidelity registry for digital and physical rarities where every provenance check and edition claim is a micro-settlement. Artists issue assets; buyers pay $0.01 to verify authenticity or claim the next serial in a sequence, eliminating the overhead of gas and friction of subscription tools. It turns every 'check' into a direct micro-royalty for the creator.

The primitive.

full primer →

Access to the limited print tracking 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 moving from a 'database' model to an x402 'metered' model, the act of verification becomes a revenue stream. Collectors pay a negligible fee to ensure their print is authentic, and artists are incentivized to maintain active registries because every interaction generates immediate USDC.
