Yardage · x402

A hyper-liquid ledger for textile scraps and deadstock. Pay-per-entry to list high-fidelity fabric scans, and pay-per-match to unlock shipping credentials and fiber composition data. Every scrap is a tradeable asset, precision-metered to favor the micro-designer over the industrial landfill.

The primitive.

full primer →

Access to the material bartering 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 listings and data-access into $0.01 micro-transactions, we eliminate the subscription barrier for independent designers while creating a high-velocity dataset of textile availability. The pay-per-unlock model ensures the facilitator only settles when a designer finds the exact material match.
