Drape · x402

A high-fidelity textile physics engine where every draping simulation is a paid computation. Users pay 0.01 USDC to render a fabric's gravity, shear, and friction on a 3D avatar. Pro designers monetize their proprietary 'weaver' files by charging per download or per simulation run. No subscriptions—just pay-per-poly cloth physics for precise garment prototyping.

The primitive.

full primer →

Access to the online fabric simulation 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 'hub' to a 'metered engine' turns heavy CPU/GPU simulation tasks into a revenue stream. By pricing the computation and the intellectual property (the fabric data) via x402, it prevents bulk scraping of textile research.

material provenance
FiberProof · x402
Micro-verify the origin of every thread. Designers pay 0.01 USDC to pull a real-time provenance certificate via HTS transfer, instantly unlocking a secure Hedera transaction id that validates organic claims for the consumer. Zero subscriptions—pay only per fabric roll audited.
design copyright
PatternGuard · x402
A high-throughput timestamping layer for garment patterns and textile prints. Designers pay 0.01 USDC to instantly log a cryptographic fingerprint of their work to Base, generating a verifiable 'Proof of Creation' certificate. This replaces slow, expensive legal filing with a sub-cent digital notary that protects designs the moment they leave the iPad.
