PROOF-SHEET · x402

A metadata-in-frame camera plugin that seals every slider adjustment, crop, and color grade as a cryptographic proof. $0.01 USDC per 'Save' triggers an HTS transfer transfer, anchoring the edit hash to Base and returning a permanent provenance receipt. Instant authenticity for professional workflows without gas friction.

The primitive.

full primer →

Access to the edit provenance 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 switching to a pay-per-seal model, the app treats 'truth' as a micro-service. Pros pay for the security of verifiable edits, while the facilitator handles the Base gas, making the transaction feel like a native app feature rather than a blockchain interaction.

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.

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.
