BORDERLINE · x402

A programmable border-engine where every aesthetic shift is a transaction. Collectors or algorithms pay 0.01 USDC to 'Cycle' the visual context of an asset. Use the x402 primitive to meter 'Gaze-Based Evolution' (auto-shifting frames based on how many wall-clocks pass) or 'Oracle-Linked Skins' (weather/price/time-of-day) where each asset state-change is a paid, verifiable event. Pay to re-frame your collection for a specific gallery mood.

The primitive.

full primer →

Access to the programmable artwork framing 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 static NFT metadata to a pay-per-mutation model, the frame becomes an active service rather than a one-time purchase. Owners can 'subscribe' their art to dynamic environment changes, creating a continuous revenue stream for the developer/artist for every border refresh.
