🎨 Visual Art · gamified art auctions

VELOCITY VOTE · x402

Bid-to-Stroke: the auction is the creation. 0.01 USDC unlocks a 10-second window to manipulate a collaborative 3D generative canvas. Every micro-payment moves the price floor and extends the timer. The final frame is minted as an NFT to the highest spender, with all 'bid-calls' distributed to the artist in real-time. Payment isn't just a bid; it's the brushstroke.

The primitive.

full primer →

Access to the gamified art auctions 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 primitiveMoving from a static bidding war to a pay-per-interaction model turns the auction into a high-velocity revenue stream. HTS transfer allows for frictionless ‘micro-bidding’ without gas-friction or pop-up fatigue, turning the UI into an addictive playground for collectors.
