SporePrint · x402

A pay-per-sample terminal where designers unlock genetic recipes and fabrication protocols for mycelium, algae, and bacterial cellulose. Instead of bulky crowdfunding rounds, innovators monetize 'Lab-Drops'—charging 0.01 USDC per recipe download or growth-parameter update, creating a real-time revenue stream for sustainable material R&D.

The primitive.

full primer →

Access to the biomaterial crowdfunding 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 primitiveBiomaterial R&D is currently gated by high academic walls or opaque startups. By atomizing access to protocols into 0.01 USDC micropayments, creators get instant liquidity while designers get high-fidelity material instructions without a subscription.

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.
color curation
