STITCH-LOCK · x402

A real-time verification layer for circular fashion. Pay 0.01 USDC to cryptographically seal the provenance of an upcycled garment, logging the transformation labor and material history. Every 'proof of rebirth' provides the creator an instant micro-settlement, turning sustainable labor into a liquid asset stream.

The primitive.

full primer →

Access to the sustainable 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 from a static NFT mint to a high-velocity attestation model where designers are paid per piece of supply chain evidence generated.
