ThreadSeal · x402

A micro-metered verification protocol where garment manufacturers pay 0.01 USDC to unlock an immutable quality seal for individual fabric bolts. Designers pay per lookup to verify tensile strength, dye-lot consistency, and compliance certificates before cutting patterns. Pay-per-batch eliminates heavy subscription costs for independent ateliers.

The primitive.

full primer →

Access to the batch quality control 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 primitiveMoving from a broad 'log' system to a granular micro-payment model turns quality data into a liquid asset. It prevents 'data dumping' by making each entry a paid certification and each retrieval a paid verification, ensuring only high-fidelity data consumes chain space.
