GhostWriter · x402

A pay-per-branch narrative engine where game designers charge per story node traversal. Instead of static NFTs, writers monetize the 'Decision Flow'. Developers pay 0.01 USDC to pull the next narrative state, variable set, or dialogue tree directly from the writer's authenticated logic. Pay-per-read triggers instant settlement for the creative lead, turning interactive scripts into metered APIs for indie games.

The primitive.

full primer →

Access to the game narrative design 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 primitiveMoving from NFT minting to x402-native micro-metering allows for granular narrative consumption. In game dev, assets are often bloated; this trims the cost to only the paths players actually take, while providing the writer with immediate, high-frequency revenue.

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.
screenwriting rights
DraftFlow · x402
A granular narrative licensing engine where screenwriters monetize at the scene level. Producers and AI pre-viz tools pay 0.01 USDC to 'Read & Reference' specific plot points or dialogue blocks. Each interaction triggers an HTS transfer transfer directly to the script's contributors, turning a static PDF into a metered IP asset. Payment is the permission layer for adaptation.
