StitchTrack · x402

A digital sketchbook where every stroke is a commit. Pay 0.01 USDC to 'Save & Seal' a sketch state to Base. Instead of a single final NFT, designers build a micro-payment audit trail that proves the evolution of an original garment, creating a verifiable 'proof of process' that protects against AI scraping and design theft.

The primitive.

full primer →

Access to the fashion sketching 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 primitiveBy shifting from 'one-time minting' to 'per-save settlement,' the app creates a high-velocity utility for USDC. It captures the value of the creative process rather than just the final product.
