🎨 Visual Art · generative art minting

Gen-Seed · x402

A headless seed-to-string engine where 0.01 USDC triggers a unique generative iteration. Instead of a heavy upfront minting fee, users pay per 'Evolution Sign-off.' Artists deploy logic; collectors pay per high-fidelity render, receiving a Hedera transaction id as proof of unique generation. The payment is the shutter click.

The primitive.

full primer →

Access to the generative art minting 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 moving from 'Art as a Service' to 'Payment as the Shutter,' we capture the high-frequency nature of generative exploration. x402 eliminates the friction of gas-estimation for collectors, turning every 0.01 USDC micro-payment into a cryptographically signed creative act.
