GreenThread · x402

A high-resolution provenance layer for sustainable textiles. $0.01 USDC to mint a permanent, verifiable batch record or to query a fabric's deep-tier environmental audit. Designers pay per lookup to verify GOTS/GRS certifications, preventing greenwashing at the pattern-cutting table. Brands pay per batch to register supply chain data, creating a machine-readable 'green' identity for raw materials.

The primitive.

full primer →

Access to the sustainable textile 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 shifting from a subscription SaaS to a $0.01 per-query model, the app allows small-scale designers and AI-driven procurement tools to verify textile ethics without overhead. Payment acts as the audit trail; every transaction hash is the proof of verification.
