LensSeal · x402

A sub-cent ledger for digital authenticity. Pay 0.01 USDC to seal every shutter press, edit, and transfer into an immutable provenance chain. Creators monetize the 'truth' by charging viewers to verify the original metadata and historical edits of high-value media.

The primitive.

full primer →

Access to the provenance tracking 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 provenance into a pay-per-event action (HTS transfer), we replace expensive high-fee minting with atomic 0.01 USDC event logging. This makes constant metadata updates financially viable for working photographers.
