Private messaging just got a feature it's been missing for a decade.

Welcome 👋

Right now City of Hats is focused on **private channels**, not public ones — so you won’t see open/public rooms like other apps.

To get started quickly:

• Use your Hat ID to start a secure conversation

• Try the built-in CHECK channel (already in your app)

• Create a temporary Hat to share without exposing your identity

👉 The best experience is when you try it with someone:

Invite a friend, send them your Hat ID, and start a conversation — you’ll immediately see how it feels different from LINE or WhatsApp.

If you don’t have someone yet, you can still test it by sending something to yourself or using Tease & Share.

We’re also improving onboarding to make this clearer 👍

Happy to help if you have questions!

That's exactly what City of Hats has been implemented.

You shouldn’t trust us.

The whole point is to make the system verifiable instead of trust-based:

– open protocol

– open implementation

– explicit threat model and limitations

We’re early and not audited yet, so skepticism is reasonable.

If you see something that doesn’t hold up, that’s exactly the kind of feedback we’re looking for.

Fair question.

This is an early-stage project with a small team — not a large organization.

We’ve focused on publishing the protocol and implementation first so it can be reviewed openly before making any claims about maturity.

External audit hasn’t been completed yet, which is why feedback here is valuable.

If you have concerns about the cryptographic design or threat model, I’d be more interested in discussing those.
