$0.01 — pay-per-pixel. A hyper-granular collaborative mural where every stroke, color change, or vote to 'lock' a section requires a signature-authorized micropayment. No free riding in the digital commons: influencers and artists pay USDC to overwrite or defend their territory. Settlement happens instantly per interaction, turning the canvas into a real-time sovereign economic battlefield.

The primitive.

full primer →

Access to the collaborative art governance 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 DAOs suffer from voter apathy and gas-heavy governance. By making every edit a metered x402 payment, the 'cost to participate' acts as a sybil-resistance mechanism and direct revenue stream for the vault, ensuring only high-conviction strokes are made.
