ZeqText is a full-stack encrypted messaging application built on the TESC (Temporal Entangled State Channels) protocol. Every message is encrypted with AES-256-GCM using Zeqond-indexed IVs and authenticated with Phase-Locked Authentication Tags (PLATs) that expire every 0.777 seconds. Your TESC UID serves as your phone number. Features: real-time messaging via WebSocket, typing indicators, read receipts, offline message delivery, contact management, and end-to-end encryption where the server never sees plaintext.
