Germ DM x ATProto is Now in Beta
Germ DM is now a Bluesky messenger.
We’ve integrated AT Protocol, the open social layer that powers Bluesky, directly into our iOS app—which means E2EE DMs have finally come to the Atmosphere!
ATProto lets us meet and discover, but real connections form in private.

Integrating Germ with AT Protocol
End-to-end encrypted Germ DM is now a Bluesky messenger. In this technical post, we introduce the architecture of Germ’s integration with AT Protocol. From the beginning, Germ has been building for an interoperable E2EE ecosystem, and this extends to our integration with AT Protocol. We’ll define the goals that we set for this integration, detail our first steps toward those goals, and outline our path forward.

Join the beta waitlist: Germ DM is integrating with your Bluesky handle!
We’re Germ, the secure messaging app that puts your boundaries and your priorities first. No phone numbers, no tracking, no pressure.
We’ve been live in the iOS App Store with standardized, MLS-powered end-to-end encryption for a minute. Now, we’re bringing secure messaging to your ATProto handle—the username you use on Bluesky and across the Atmosphere in apps like Skylight, Smoke Signals, and more.
With this integration, we’re making it seamless to get where you’re trying to go—into a secure chat—the way you already know each other—as your handles.
