FinalDraft Trust · x402

Pay-per-version professional provenance for screenwriters. Instead of high-friction NFT minting, writers sign 0.01 USDC x402 calls to 'stamp' screenplay drafts. Each stamp provides a cryptographic proof-of-existence and immutable time-record on Hedera. Producers and agents pay a 0.05 USDC micro-fee to unlock a watermarked PDF for reading, with payments flowing directly to the writer’s the embedded wallet-secured wallet. It turns the script ledger into a high-velocity, metered rights-management engine.

The primitive.

full primer →

Access to the screenwriting rights 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 shifting from bulky NFT minting to x402 micropayments, we remove the technical overhead for non-crypto writers while enabling a new 'pay-to-read' primitive. The facilitator handles the gas, and the writer pays only for the 'stamp' action, while readers pay to 'unlock.'

poetry archiving
VerseLedger · x402
A granular attribution layer for poets. Instead of a one-time mint, VerseLedger meters the "Proof of Originality." Pay 0.01 USDC to cryptographically timestamp a stanza or signature, or 0.01 USDC to query the chain for a similarity check against the ledger. It turns the archive from a static list into a pay-per-verification utility for publishers and literary scouts.
interactive storytelling
PlotLine · x402
A real-time collaborative logic engine for fiction where every narrative branch is a pay-per-vote micro-transaction. Authors publish 'Fractured Chapters' where the plot path is gated by liquidity; the story only progresses when the collective pool for a specific outcome hits its threshold. 0.01 USDC per vote ensures skin in the game while preventing bot-spamming of plot arcs. Readers don't just consume; they fund the creative direction one sentence at a time.
