LENSFLOW · Pay to Verify

Embed metadata-rich caption files (SRT/VTT) into video players that only render upon a signed QUIP micro-transaction. Pay the translator or writer per view, not per project. Every time a viewer toggles your CC track, you settle a sub-penny royalty instantly to your Privy wallet. Validates ownership through consumption rather than static minting. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
