XChat, the new messaging platform from X, has officially launched globally, replacing the traditional Direct Messaging system.

Elon Musk has announced the launch of XChat, a new messaging feature that utilizes Bitcoin as its encryption standard, enhancing security for users.

XChat features end-to-end encryption, vanishing messages, and supports file sharing, audio, and video calls, enhancing secure communication for users.

The platform is built using Rust, a programming language known for its focus on security and efficiency, enabling a robust architecture.

The technology behind XChat utilizes the Signal protocol, known for its strong encryption, but aims for a more decentralized and censorship-resistant approach.

XChat's launch could disrupt the messaging landscape by challenging WhatsApp's dominance, leveraging X's existing user base of over 436 million daily users as of early 2025.

The announcement has generated significant excitement in crypto communities, with users expressing enthusiasm over potential security benefits.

The messaging tool is designed for anonymity and portability and does not require a SIM card or cellular number, unlike competitors such as WhatsApp and Telegram.

For verifying identities, XChat may use ECDSA, the same digital signature method as Bitcoin, and could also implement advanced options like EdDSA for faster signature verification.

Musk's push for enhanced privacy led to the pause of the previous encrypted DM feature in May 2025, focusing resources on XChat's development.

XChat represents a significant step in Musk's vision for X as a multifaceted platform, with its impact on secure communication and the tech landscape expected to unfold in the coming months.

A 256-bit ECC key provides similar security to a 3072-bit RSA key, making ECC a faster and less resource-intensive option for cryptography.
