What is XChat?

XChat is a brand-new messaging feature built right into the X app. It’s designed to give users a safer, more flexible way to communicate, going head-to-head with popular chat apps like WhatsApp, Signal, and Telegram.

It comes with end-to-end encryption, vanishing messages, calls without phone numbers and more.

XChat Key Features

Here’s what XChat brings to the table –

• End-to-End Encrypted Chats – Messages are fully secure, only you and the person you’re chatting with can read them.
• Disappearing Messages – Just like on WhatsApp or Signal, you can set messages to vanish after a certain time, giving you more control over your privacy.
• No Phone Number Needed – You can make both audio and video calls without linking a phone number, something rare among major messaging apps.
• File Sharing – You can send images, documents, and other media directly through chats.
• Extra Security – There’s a 4-digit passcode option to lock and protect your chats, adding another layer of privacy.
• Built with Rust – The entire chat feature is built using the Rust programming language, known for performance and safety.
• Bitcoin-Style Encryption – Musk says the app uses encryption similar to Bitcoin’s cryptographic system, likely referring to elliptic curve cryptography.

With these features, Elon Musk isn’t just tweaking social media, he’s aiming to reshape how we message and stay secure online.

XChat is now live inside the X app, marking a big step toward Musk’s long-promised all-in-one communication platform.
