DeepProof · x402

Instantly verify the provenance and integrity of any video asset. ContentTrust enables filmmakers to sign metadata and users to verify authenticity for 0.01 USDC. Every verification call returns a Hedera transaction id, creating an immutable audit trail that prevents deepfake manipulation and preserves original intent. Pay per verification, protect per frame.

The primitive.

full primer →

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

Why this primitiveBy moving from a static 'badge' to a pay-per-verification x402 model, the app transforms into a live security protocol. This creates a sustainable micro-economy for videographers to monetize their reputation and for viewers/newsrooms to filter truth from AI-generated noise.
