Elon Musk has launched a new messaging feature on X called XChat, placing the platform in direct competition with messaging apps like WhatsApp, Telegram, and Signal.
The rollout introduces encrypted messages, disappearing chats, and file sharing, all integrated into the existing X platform.
XChat is a total rebuild. Musk revealed the messaging system has been reconstructed from the ground up using the Rust programming language, which is known for its strong memory safety and performance.
He also claims it uses a form of “Bitcoin-style” encryption, a phrase that has drawn attention of security experts due to its lack of clarity.
“All new XChat is rolling out with encryption, vanishing messages and the ability to send any kind of file. Also, audio/video calling. This is built on Rust with (Bitcoin style) encryption, whole new architecture,” Musk posted on X.
Here’s what’s changing:
- End-to-End Encryption: Conversations are now designed to be private. Only the sender and recipient can read messages.
- Vanishing Messages: Users can set timers for chats to disappear, offering more control over personal data.
- Universal File Sharing: The feature allows any kind of file to be sent—images, documents, videos—without restrictions.
- Audio and Video Calls: Available across devices and operating systems, with no phone number required.
For now, these features are only available to a limited number of users, primarily those on the platform’s paid tiers. Wider access is expected in the coming weeks, but no exact timeline has been announced.
Security professionals have questioned the encryption claims, arguing that comparing the app’s security to Bitcoin is misleading.
Ian Miers, assistant professor of Computer Science at the University of Maryland, stated, “Bitcoin primarily uses signatures, not encryption. This is like saying, we decided to run our rocket on water, since NASA uses Hydrogen and Oxygen.”
“Needless to say ‘Bitcoin style’ and ‘Rust’ are not descriptions of an encryption scheme, nor are they strong indicators of security for a messaging app. Also, unless encrypted DMs are only in app, odds are they aren’t just in Rust.”
What makes this move significant is its role in Musk’s vision. He’s not hiding the fact that he wants to turn X into a multipurpose platform, a Western version of China’s WeChat. The addition of a secure, flexible messaging tool is just one step in that transformation.
Last year, Musk announced plans to introduce payments and even dating features within the platform. Now, with the foundation of a private communications tool in place, X is inching closer to becoming a one-stop digital hub.
