Pattern Proof · x402
A high-fidelity CAD silhouette vault where designers pay 0.01 USDC to 'cut' (fork) a professional block or 'seam' (merge) metadata into a collaborative tech pack. Every structural iteration is an on-chain commit, ensuring pattern-makers are paid for the underlying geometry before a single stitch is sewn.
The primitive.
Access to the design silhouette sharing engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so fashion designers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveMoving from simple 'sharing' to 'micropayment-gated CAD blocks' creates a high-velocity marketplace where the primitive is the design foundation itself. x402 allows for granular licensing of shapes, where a designer pays per iteration/download rather than a heavy upfront seat license.
