Mejhool offers a comprehensive, secure communication experience to its users by allowing them to send text messages, make voice and video calls, and share images, documents, emojis, HZM stickers, and more, while maintaining their privacy. With the app, users can enjoy all the features of top-tier chat apps like WhatsApp, Telegram, and Signal, but with the added assurance of peer-to-peer or decentralized connections that eliminate the risk of third-party data breaches.



Private Messaging App.

Mejhool Private Messaging is a Decentralized web and mobile app with peer-to-peer text messaging, decentralized file transfer and voice-over-IP service. It allows users to send text, make voice and video calls and share images.


  • Voice and Video Calls
  • Available on all platforms including mobile and Desktop
  • Group Chat
  • Security/Privacy/Decentralized by default
  • End-to-end encryption
  • Photos, Audios and Videos Sharing
  • Documents Sharing
  • Completely Decentralized


The app is completely based on decentralized architecture which uses multiple servers/nodes in place of a single centralized server/node. Each of these servers are independent of each other and act as an independent master server and at the same time taking the necessary workloads as part of load balancing.

There is no central authority to control users' data, control is distributed between participants in the system/server/nodes, rather than being held by a central authority. The most secure decentralized end-to-end encrypted messaging apps send messages by routing them through a random selection of nodes on the network. The set of nodes being used changes with every new message. This additionally allows for zero downtime for the apps as the server would never go down. Also, no malicious activity can be performed as every time the data is being communicated through random nodes.

Security and Encryption

Decentralized encrypted messaging is based on a trustless system. You don’t need to place your trust or privacy in the hands of a central or controlling. There is no central authority to collect, sell or give away your conversation data. Also, they cannot control the availability of your app.

End to End Encryption

Users have the need to share their private moments; however, these moments are meant only for the sender and the receiver. With the end-to-end encryption, all the messages, files and calls are secured so that only the sender and the receiver can read or listen or view them and nobody else including us in any circumstance.

Web 3.0

Mejhool is completely Web 3.0 based. Web3 (Web 3.0) is a collection of JavaScript libraries that lets you interact with an Ethereum node remotely or locally. Simply, it provides us with an API to use so we can easily work with the blockchain. Web 3.0 works as a wrapper for JSON RPC to connect to a remote or local Ethereum node with either an HTTP or IPC connection.


MetaMask Wallet

No real user Identity

There is no real user identity in Mejhool, users are only identified by their MetaMask wallet address which uniquely identifies the user and is used for user registration and login.

Credit cards have made it extremely common for people in the West to carry no cash; some even depend on their cell phones for Apple Pay. In the Arab World, however, it is still more common to pay in cash. Sometimes, it is the only method accepted. But cryptocurrency has allowed people to move money into a digital format while profiting from their investments.
