STITCH-TRACE · x402

A decentralized provenance ledger for high-end garments. Pay 0.01 USDC to append or verify a lifecycle event (fabric sourcing, dye lab tests, sewing completion) to a design's immutable chain of custody. Turn 'Made in Italy' from a label into a verifiable, audit-by-call timeline.

The primitive.

full primer →

Access to the design lifecycle tracking 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 turning supply chain updates into granular pay-per-event transactions, brands move from nebulous 'sustainability claims' to a metered, cryptographically signed ledger. x402 ensures that only authorized entities (suppliers, ateliers) can update the record for a nominal fee, preventing data spam and ensuring high-integrity tracking.
