What is City of Hats?

City of Hats is a secure messaging platform with built-in cyber intelligence. It requires no phone number, email, or personal information. You create anonymous Hat identities and communicate through end-to-end encrypted channels with post-quantum key exchange, while accessing security intelligence tools directly inside the chat.

What are Security Modes?

Security Modes are nine granular content controls unique to City of Hats. They include View Once (self-destructing messages), Recall (pull back sent messages), Sealed File (PIN-locked content), Unlock Content (paid access), Verified Eyes Only (biometric verification), GeoLock (location-restricted viewing), Voice Lock (voice verification), Hold to Reveal (continuous touch required), and Certified Send (cryptographic proof of receipt).

What is the CHECK intelligence bot?

CHECK is a built-in intelligence bot inside City of Hats. Type commands like 'check email', 'check phone', 'check domain', 'check ip', 'check username', or 'check password' directly in the chat to receive instant security reports. Results include risk scoring, credential exposure detection, SIM swap detection, IP reputation analysis, and more — delivered as self-destructing secure reports.

Is City of Hats really anonymous?

Yes. City of Hats uses a zero-knowledge architecture. No phone number, email, or personal information is required to create an account. You communicate through anonymous Hat identities. The platform cannot read your messages, does not create cloud backups, does not harvest metadata, and keeps no logs.

What encryption does City of Hats use?

City of Hats uses the Double Ratchet protocol for forward secrecy, CRYSTALS-Kyber hybrid key exchange for post-quantum protection, and AES-256-GCM symmetric encryption for every message, file, and call. The zero-knowledge architecture means the platform cannot decrypt any user content.
