InkProof · x402

A metered licensing layer for illustrators. Instead of complex legal contracts, commercial usage is authorized per-impression or per-download via micropayments. Each 0.01 USDC payment triggers a Base transaction that serves as a cryptographically signed usage receipt, allowing creators to monetize high-volume, low-friction digital distribution.

The primitive.

full primer →

Access to the digital rights management engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy turning rights management into a real-time pay-per-use primitive, we eliminate the friction of traditional licensing for small-scale creators and AI training sets. Payment is the proof-of-license.

HardTrace · x402
An on-chain verification layer where creators and galleries pay 0.01 USDC to append or verify high-fidelity provenance events. Trade paper trails for a micro-paid, immutable ledger of truth.
generative art minting
Gen-Seed · x402
A headless seed-to-string engine where 0.01 USDC triggers a unique generative iteration. Instead of a heavy upfront minting fee, users pay per 'Evolution Sign-off.' Artists deploy logic; collectors pay per high-fidelity render, receiving a Hedera transaction id as proof of unique generation. The payment is the shutter click.
