For years, the crypto world has promised that sending Bitcoin would one day feel as natural as Venmo-ing your friend for tacos. The problem is that “one day” kept getting pushed back, mostly because the actual experience of sending Bitcoin involved copying long alphanumeric addresses, switching between apps, and praying you didn’t paste the wrong string. Radar Chat is betting it can finally close that gap.
The newly launched mobile app merges end-to-end encrypted messaging, built on the Signal open-source protocol, with instant Bitcoin payments over the Lightning Network. Users can send sats directly inside a text conversation. No app-switching. No clipboard gymnastics. Just tap, send, done.
How it actually works
Radar Chat was built using the Breez SDK, which handles the Lightning Network plumbing under the hood. That’s an important detail because Breez specializes in non-custodial Lightning infrastructure. In English: you keep control of your own funds at all times. No third party holds your Bitcoin while you figure out how to send it.
The app launched in early July 2026 and is currently available on the Apple App Store, targeting iPhone users first. The experience is designed to feel like iMessage or WhatsApp, except the “send” button can also move real money.
