Radar Chat Launches iOS App Merging Signal Messaging with Lightning Payments

Radar Chat released its mobile app on July 7 2026, combining Signal Protocol encrypted messaging with self-custodial Bitcoin Lightning payments. The Cake Wallet team’s open-source product enables users to send sats directly inside chats without leaving the conversation or relying on custodians. Built on the Breez SDK and initially available via the Apple App Store, the app targets the firm’s two million users to boost Lightning Network adoption. Earlier coverage highlighted the iOS-first rollout and privacy focus, while later pieces noted competitive risks and lack of immediate user metrics.
