CanvasSwap · x402

Curate and trade digital canvases where every view, bid, and swap is metered via micropayments. A high-velocity 'Art Tinder' where artists earn 0.01 USDC for every swipe-right (buy-interest) and collectors pay-per-offer. Settlement occurs instantly, turning low-fidelity discovery into high-signal liquidity.

The primitive.

full primer →

Access to the peer-to-peer art exchange 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 replacing high-friction flat fees with 0.01 USDC per-interaction (view high-res, place bid, reveal hidden metadata), the protocol monetizes the discovery process itself, not just the final sale. This creates a sustainable income stream for active artists even when pieces aren't trading.
