Pars Messenger Android

Private messaging for the Pars Network - Built on pars.network

Overview

Pars Messenger Android is a privacy-focused messaging app for the Pars Network, featuring end-to-end encryption with post-quantum cryptography. Messages are stored on decentralized storage nodes and routed through onion routing for maximum privacy.

Current Status

Integration Status: In Progress

The Android app uses libsession-util for networking. Full Pars Network integration requires modifications to the underlying C++ library.

What Works

• Building and running the app
• Core messaging functionality

What Needs Work

• Network configuration for Pars SessionVM
• libsession-util modifications
• Pars branding updates
