P2P Chat & File Transfer

A secure, serverless peer-to-peer chat application built with Rust and iroh.

Features

• Decentralized: No central server; peers connect directly via QUIC and NAT traversal.
• Commands:
  • /connect <peer_id>: Connect to a peer.
  • /nick <name>: Set your display name.
  • /file <path>: Send a file.
  • /accept <file_id_prefix>: Accept a file transfer.
  • /mic: Select microphone input.
  • /speaker: Select speaker output.
  • /bitrate <kbps>: Set audio bitrate.
• Cross-Platform: Works on Linux, Windows, and macOS.
  • File sharing supported on all platforms.
  • Voice/Screen share (Linux only for now, requires PipeWire).
