TrueLens · x402

Photographers and journalists pay 0.01 USDC to seal a photo's origin, timestamp, and GPS coordinates into an immutable cryptographic proof. Every metadata 'anchor' generates a permanent Base transaction hash, providing instant proof of authenticity for newsrooms and collectors without forcing users to own ETH. Buy truth one frame at a time.

The primitive.

full primer →

Access to the photo metadata 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 turning metadata verification into a per-usage fee, we solve the 'junk data' problem. The x402 model makes 'Proof of Reality' affordable for smartphone users while ensuring the storage cost is covered by the creator at the moment of capture.

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.
