OPCam turns your iPhone into a tamper-evidence camera for fieldwork, inspections, and any photo that has to be trusted. • Time, GPS coordinates and address are burned into the original photo — they can't be edited out • Every photo gets a SHA-256 fingerprint of the exact image file you share — so anyone holding the photo can recompute it and check it themselves • Optional on-chain anchor: the fingerprint is recorded on Optimism, so anyone can independently verify the photo existed at that time • Record library with timeline, place and live map views • Choose exactly which fields go into the watermark • 24 languages Your photos stay yours — saved to your photo library. The on-chain anchor stores only a hash fingerprint, never the image.
