$0.01 — Reveal the next panel. A branching, collaborative graphic novel where your micro-payment triggers the generative expansion of the narrative. No subscriptions, no ads; pay-per-frame to influence the story's direction. Every 'turn' is a signed HTS transfer transaction that instantly settles the artist and the compute agent providing the AI-assisted art.

The primitive.

full primer →

Access to the interactive storytelling engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveMoving from 'NFT minting' (high friction, ownership focus) to 'Pay-per-Panel' (low friction, consumption focus). x402 allows for a 'Netflix-style' consumption experience with a 'Quarter-in-the-Arcade' payment model, creating a direct value link between reading a page and rewarding the creator.
