Elon Musk announced the rollout of a new feature called “XChat” for select X Premium subscribers, set to reach all paying users within a week. XChat includes enhanced messaging features such as full encryption by default, vanishing messages, the ability to send file attachments, and audio/video calls without a phone number. The service is built using "Rust with (Bitcoin style) encryption.” Musk envisions integrating messaging with financial transactions, aiming to launch X Payments later this year, similar to WeChat's model in China. Despite challenges in attracting Western consumers to comprehensive platforms, Musk's experience in payments may help make XChat appealing. The updated XChat begins its rollout this week, subject to potential scaling issues.
