## Description

Stamp every photo with time, GPS and address, fingerprint it with SHA-256, and anchor it on-chain for independent verification.

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.
