Provenance · x402

A non-destructive editing ledger where every adjustment layer is captured on-chain. Producers pay 0.01 USDC to 'Rollback' or 'Fork' an edit state, turning creative history into a verifiable, liquid asset. Pay-per-reversion ensures accountability while rewarding creators who share their workflow 'recipes' for others to learn from.

The primitive.

full primer →

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

Why this primitiveBy monetizing the granular steps of the editing process (the 'history' rather than just the 'result'), we shift the value from a static JPEG to the intellectual property of the process itself. x402 handles the micro-metering required for high-frequency undo/redo or state-branching actions.

copyright registry
Snapshot Proof · x402
A high-frequency copyright layer for the screenshot era. 0.01 USDC per EIP-712 signature to timestamp image hashes on Hedera. Creators meter every license issuance, and platforms pay to verify provenance in real-time. No subscriptions, just provable ownership on-demand.
image authenticity
TrueLens · x402
A pay-per-seal protocol for photographers. Every shutter click or metadata injection requires a 0.01 USDC micro-settlement to anchor the image's SHA-256 hash and geolocation to Base. Instead of a subscription, users pay only for 'Truth-as-a-Service,' generating a cryptographically verifiable 'Proof of Origin' receipt. Protect your IP and verify reality in an era of Deepfakes, one cent at a time.
royalty automation
SHUTTER · x402
A headless licensing layer for digital imagery. Instead of subscription silos, developers and creators pay $0.01 USDC to programmatically unlock high-res source files or commercial rights. Every 'GET' request triggers an HTS transfer transfer directly to the photographer, enabling sub-cent licensing for AI training, social feeds, and micro-publishing.
