Stitchflow · x402

A modular design canvas where every brushstroke, pattern overlay, or seam tweak is a $0.01 micro-contribution. 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.

The primitive.

full primer →

Access to the collaborative design 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 primitiveShifts collaboration from slow DAO voting to high-frequency aesthetic iteration. x402 turns the canvas into a metered coordinate system, ensuring every contributor has economic weight behind their design choices.
