Ephemeral. Encrypted. Zero-Knowledge.
Communicate when it matters most — then leave no trace. Hats, Dead Drops, and Warrant Canary, built for organizations that refuse to compromise on security.
Work email required. No phone number. No contact list. No message history.
Three tools. One principle: nothing persists.
Each Secure Channel product is purpose-built for a different communication need — but they all share the same zero-knowledge, ephemeral architecture.
Hats — Encrypted Chat
Temporary, anonymous identities for real-time encrypted conversations. No phone number, no contact list, no history. When the Hat expires, everything disappears.
Learn More →Dead Drops — One-Time Messages
Send encrypted, self-destructing messages with retrieval limits and burn-on-read. Perfect for credentials, sensitive instructions, or whistleblower communications.
Learn More →Warrant Canary — Transparency
A cryptographically signed, public-facing transparency statement. If we ever receive a government data request, the canary stops singing.

Secure Channels are designed to be simple for users and impossible for everyone else — including us.
Verify with Work Email
Register using your organizational email. No Gmail, no Yahoo, no disposable addresses. Your email is hashed and never stored in plaintext.
Create a Hat or Dead Drop
Spin up an anonymous identity (Hat) for real-time chat, or create a Dead Drop for one-time encrypted message delivery.
Communicate Securely
End-to-end encryption. Zero-knowledge architecture. We cannot read, intercept, or recover your messages — by design.
Auto-Destruct
Messages burn on read, expire on schedule, or get destroyed when you say so. Once gone, gone forever — no backups, no recovery.
Secure Channels are intended for legitimate organizational use and are subject to usage limits and abuse monitoring.
Built so we can't betray your trust — even if we wanted to.
Our zero-knowledge architecture means City of Hats has no technical ability to access, decrypt, or recover your communications.
Zero-Knowledge
We cannot read your messages. We don't store encryption keys. There is nothing to hand over.
No Phone Required
No phone number, no contact list, no social graph. Hat IDs replace personal identifiers entirely.
Ephemeral by Design
Burn-on-read, time-limited, retrieval-capped. Every message has an expiration — and we enforce it at the infrastructure level.
Enterprise Compliance
SOC 2 ready. GDPR, PIPEDA, and Thailand PDPA aligned. Warrant Canary provides public transparency.
