What is City of Hats?

City of Hats is a secure messaging platform introducing a new concept called location-controlled messaging.

Messages can be locked so they can only be opened inside a specific geographic area defined by the sender. Access can be verified using telecom network signals or GPS depending on the region.

The platform also integrates telecom-based verification through AIS in Thailand, helping confirm device ownership and reduce account impersonation.

This approach creates a new type of conditional communication where a message can only be accessed under certain physical conditions, adding an additional layer of security beyond traditional end-to-end encryption.

City of Hats is available on Google Play and Microsoft Store, with an iOS version currently awaiting App Store approval.
