SceneStamp · x402

Pay-per-write metadata anchoring for collaborative pipelines. Instead of a monolithic database, animators pay $0.01 USDC to permanently stamp Frame-Level JSON (composition, lighting, focal length) onto the Base ledger. SceneMeta enables a 'pay-per-query' model where VFX vendors or AI renders pull exact scene state via HTS transfer authorized reads, ensuring the metadata stays with the asset across every handoff.

The primitive.

full primer →

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

Why this primitiveBy making every metadata write a micro-transaction, technical directors can audit the exact flow of scene changes while ensuring the data is decentralized. It transforms metadata from a sidecar file into a verifiable, paid event.

frame provenance
IMPRINT · x402
A frame-by-frame provenance layer where animators pay-per-seal to cryptographically anchor work-in-progress frames to Base. Studios and agencies pay-per-verify (0.01 USDC) to audit the derivation path of any asset, ensuring zero unauthorized AI-injection or frame-snatching. Proof of authorship is now a metered utility.
script rights tracking
ScriptMint · x402
Turn screenplays into metered assets. Producers pay $0.01 per page-read via HTS transfer, with instant USDC settlement to the writer. Unlock high-resolution downloads or character bibles for a micro-fee. Every access event is an on-chain receipt, creating an immutable paper trail of who has read the script and when—eliminating 'idea theft' disputes while providing writers with instant, granular revenue.
crowd animation funding
DirectorSign · x402
Turn animation production into a real-time meritocracy. Animators upload character design variants or storyboard beats behind x402 gates. Supporters don't just 'vote'; they pay 0.01 USDC to unlock and sign off on specific creative directions. Each micropayment is a granular vote of confidence that instantly streams to the production wallet, enabling frame-by-frame funding where every creative pivot is validated by the crowd's capital.
