SyncStream · Paid Certificate

A real-time synchronization engine for multi-angle footage. The app settles a Base tx for every finalized sync, anchoring the edit signature to the chain for verifiable creative provenance. Create a rough cut, pay for the compute, and export the EDL instantly. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.

One 0.01 USDC payment turns the multi-camera editing record into a signed certificate videographers can email, attach or archive — and the page proves who signed it without asking anyone to trust the server.
