Radar Chat debuted July 7, turning Signal chats into Bitcoin Lightning payment rails for up to 70 million users; see how the fork works and what to monitor.

Radar Chat, a fork of Signal released on July 7, lets users send and receive Bitcoin instantly via the Lightning Network without custodial intermediaries, aiming at Signal’s estimated 70 million monthly active users【2】. The launch arrives amid growing regulatory pressure on private messaging, positioning the app as a privacy‑focused payment tool for non‑Bitcoiners and those seeking financial freedom.

| Payment tech | Lightning via Breez Spark SDK (self‑custodial) |

## How Radar integrates Bitcoin payments  
Radar builds on Signal’s open‑source code, copying and extending it to add a Lightning‑based payment layer. By using the Breez Spark SDK, the app avoids the complexity of running a full node or managing inbound liquidity, encrypting the user’s seed phrase into the Signal profile backup for seamless recovery【1】. This design mirrors Apple’s iMessage cash flow, allowing payments without a separate app while keeping keys in the user’s device.  

## Market context and risks  
The timing aligns with EU chat‑control proposals and UK VPN restrictions, which could tighten surveillance on messaging platforms【2】. Radar’s reliance on Signal’s servers means the Signal Foundation could block third‑party forks if client signatures conflict, a risk highlighted by the team despite precedent from other forks like Molly【1】. Funding details remain opaque, with the team raising an undisclosed amount from angel investors and Ego Death Capital【1】.  

## What to watch  
- **Signal Foundation response** – any official statement or technical block of Radar’s client could halt adoption.  
- **Feature rollout** – planned additions such as desktop app, bill‑splitting, stablecoin support, and privacy‑preserving cloud backups may drive user growth.  
- **Regulatory developments** – EU chat‑control legislation and UK VPN restrictions could boost demand for privacy‑first payment tools like Radar.  

Radar’s debut demonstrates that Bitcoin’s Lightning Network can be embedded into mainstream messaging apps without sacrificing user experience, but its longevity hinges on Signal’s tolerance for forks and the broader regulatory environment.
