PlotProof · x402

Secure your IP at the speed of thought. PlotProof enables authors to notarize narrative beats, character arcs, and full drafts directly to Base. Every 'Proof' event anchors your creative timeline with a cryptographic timestamp, creating an immutable trail of originality that protects against plagiarism while providing a verifiable history of your story's evolution. Pay only when you protect.

The primitive.

full primer →

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

Why this primitiveBy turning narrative validation into a pay-per-use primitive, we replace expensive legal registrations with 0.01 USDC micro-notarizations. This allows writers to 'save' their progress on-chain at every milestone, ensuring their IP is defendable from the first sentence.
