Every gaze, scan, or digital derivative payout flows back to holders via high-frequency micropayment streams. Use the embedded wallet to sign into the canvas and x402 to stream ownership instantly.

The primitive.

full primer →

Access to the fractional art ownership 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 primitiveRedefines ownership from a monolithic 'buy and hold' event to a 'pay-per-fraction' utility. By using x402, the barrier to entry for fine art is lowered to the absolute minimum (one cent), enabling high-velocity secondary turnover and instant distribution of royalties without gas friction.
