Stitchflow · Paid Certificate

Instead of bulky governance votes, the design evolves through 'Proof of Stake' aesthetics; designers pay to commit changes to the master garment file. This creates a real-time, skin-in-the-game leaderboard for lead designers, where the final high-fidelity tech pack is unlocked and exported via a collective micropayment pool. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.

One 0.01 USDC payment turns the collaborative design record into a signed certificate fashion designers can email, attach or archive — and the page proves who signed it without asking anyone to trust the server.
