With Elon Musk Gradually Releasing XChat, X Abandons Old Direct, Promises Encryption, File Sending and Temporary Messages, and Signals Integrated Payments to Reduce Conversation Leakage to WhatsApp; The Dispute Becomes About Trust, Digital Identity and Who Controls the History of Personal Data.
Elon Musk confirmed XChat as the new messaging and encrypted calling system integrated with X. The rollout starts for some users and is expected to expand throughout the week, shifting X’s role from a public square to a direct competitor of WhatsApp and Telegram in private conversations.
The central point is not just a new chat, but the attempt to eliminate the bridge between a public post and a private negotiation. If XChat reduces the need to “leave X,” Elon Musk’s strategy aims to compete for something more valuable than audience: trust, file storage, and on the horizon, payments within the same ecosystem.
XChat: From Fragile Direct Messages to Conversation Infrastructure on X
XChat replaces the old direct messaging system associated with Twitter, described as insecure and limited.
-
With a cost per shot close to zero, the DragonFire laser could change naval warfare in 2027 and provide British ships with nearly unlimited defense against drones.
-
A British startup creates tires that generate electricity in electric vehicles when passing over potholes, speed bumps, and cracks.
-
Scientists have created robots made with living cells that have their own nervous system, swim on their own, explore the environment, and self-organize without any genetic engineering, and now they want to do the same with human cells.

Students create a solar-powered ambulance that operates without a plug, without fuel, and still keeps medical equipment running in remote areas.
The proposal is to bring the experience closer to what the public already recognizes in WhatsApp and Telegram, with encrypted conversations, the ability to send any kind of file, and disappearing temporary messages.
The change also reorganizes the most common flow of online interaction: it starts publicly and ends privately.
By keeping the entire journey within X, XChat attempts to reduce friction, concentrate history, and transform messages into a permanent layer of relationship, with encryption as a technical promise and as a trust argument.
“Juicebox” Encryption and the Sensitive Choice of Where the Keys Are Stored
To support XChat, the platform rebuilt the messenger’s base from scratch and adopted Rust as the main language, seeking performance and security.
The mentioned encryption uses a proprietary protocol called “Juicebox,” with a design that grabs attention for one detail: users’ private keys are stored encrypted on X’s servers, divided into fragments.
This model changes the practical experience. By using a user-defined PIN, XChat promises to recover conversations even after a phone change, something that differentiates it from rivals like Signal.
At the same time, the decision to keep the keys within X’s infrastructure has become the most debated point, as it shifts the discussion of encryption to governance: what happens under governmental pressures, sophisticated attacks, and operational failures.
Payments Within the Chat: Why Conversation Becomes the Business Layer
XChat is presented as part of a larger strategy, in which Elon Musk seeks to unify conversations, files, calls, and, in the future, digital payments within X.
The logic is simple: a conversation that is already there can become a purchase, hiring, donation, subscription, or transfer, without migrating to another app.
In practice, payments in the same messaging environment redefine what “contact” means. An account ceases to be just a profile and begins to function as an operational identity, with social backing coming from the feed and trust trails built in the chat.
When payments enter the conversation, risk and value rise together, and the messenger starts to compete with WhatsApp not only for messages but for permanence in daily life.
The Real Risk to WhatsApp Is Not Technology, It’s Habit and Network
WhatsApp dominates daily life precisely because it is predictable: groups, contacts, routines, and the feeling that “everyone is there.”
For a competitor to displace this habit, it needs to cut the switching cost, and this is where XChat’s integration with X tries to be aggressive: taking the user from the post to private without leaving the place.
However, network is a powerful defense. Even with encryption, files, and payments on the radar, XChat needs to overcome a classic obstacle: convincing that the new combination is safer and more convenient than what already works.
If XChat wins, it won’t be due to an isolated feature, but by chaining encryption, payments, and identity into a frictionless experience, something WhatsApp has historically avoided by separating networks and transactions.
“Bitcoin-Style Encryption”: Technical Precision and the Public Trust Problem
Elon Musk described XChat as using “Bitcoin-style encryption,” a phrase that creates noise because Bitcoin uses encryption primarily to authenticate transactions, not to ensure message privacy.
The most plausible reading is that XChat uses common concepts from the crypto universe, like public and private keys, but that does not replace transparency regarding implementation and audits.
And this is where the dispute is decided in detail. So far, there has been no mention of complete independent audits of the “Juicebox” protocol, which opens room for technical and political doubts about the encryption.
Without external validation, the promise of encryption becomes narrative, and narrative, in messaging systems, is worth less than proof because the cost of a mistake is high and the damage to trust is difficult to reverse.
XChat places Elon Musk at the center of a bet that impacts behavior, not just software. If encryption, payments, and integration with X are perceived as concrete gains, WhatsApp could see conversations migrate out of convenience and business strategy; if trust fails, XChat becomes just another function within a feed.
In your routine, what would weigh more in switching from WhatsApp to XChat: encryption with independent audit, integrated payments in the chat, or the convenience of resolving everything without leaving X?
Eu concordo com essa idea e vejo futuro nela, por mais que possa parecer algo arriscado, prometem uma boa segurança e uma criptografia como a do Bitcoin então, eu acho que vale a pena esse XChat, podendo facilitar a vida de muitos em um contrato e pagamentos sem precisar do uso de vários aptos para uma ação tão simples.
