ClipStamp · x402

Turn your camera roll into an immutable legal record. A $0.01 micro-transaction triggers an automated HTS transfer signed metadata hash anchored to Hedera testnet. Don't just claim authorship; prove the exact millisecond of creation to prevent AI scraping and deepfake plagiarism. Pay-per-frame authentication for creators who value their provenance.

The primitive.

full primer →

Access to the content authentication 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 shifting from a subscription model to a pay-per-timestamp (x402) model, the app captures the high-frequency needs of short-form creators. The friction of payment is eliminated by the the embedded wallet-signed auth, turning 'Protect' into a seamless, one-tap button that generates a verifiable transaction hash for every clip.
