  description

  Keychat is end-to-end encrypted, wallet-to-wallet messaging that lives in your browser side panel. No accounts. No phone numbers. No servers that can read
    your messages. Your wallet is your identity.
  
    ━━━━━━━━━━━━━━━━━━━━━━━━━
    WHAT IT DOES
    ━━━━━━━━━━━━━━━━━━━━━━━━━
  
    • Send and receive end-to-end encrypted messages between any two Ethereum-compatible wallet addresses
    • Open Keychat in a side panel without leaving your current tab
    • Connect with MetaMask, Coinbase Wallet, or any wallet via WalletConnect (300+ supported)
    • Manage multiple accounts and switch between them in one click
    • Customizable themes (Ocean, Default, and more) with light/dark mode
  
    ━━━━━━━━━━━━━━━━━━━━━━━━━
    WHY KEYCHAT
    ━━━━━━━━━━━━━━━━━━━━━━━━━
  
    🔒 PRIVACY BY ARCHITECTURE
    Every message is encrypted on your device using MLS (RFC 9420) and AES-256-GCM before it ever leaves your browser. Only you and your recipient hold the keys.
    There is no Keychat server in the middle — relays only see ciphertext.
  
    👛 NO ACCOUNTS, NO PASSWORDS
    You sign in by signing one message with your existing crypto wallet. No emails, no phone numbers, no seed phrases collected. Nothing for us to lose, nothing
    for hackers to steal from us.
  
    🌐 DECENTRALIZED BY DEFAULT
    Built on the public XMTP protocol — a decentralized messaging network that no single company controls. If we walked away tomorrow, your wallet could keep
    messaging via any other XMTP-compatible client.
  
    ⚡ POST-QUANTUM READY
    The protocol stack is designed for the post-quantum era. AES-256-GCM is already considered quantum-resistant for symmetric encryption; key exchange and
    signatures will roll over to Kyber-1024 and Dilithium as MLS-PQ matures.
  
    ━━━━━━━━━━━━━━━━━━━━━━━━━
    HOW IT WORKS
    ━━━━━━━━━━━━━━━━━━━━━━━━━
  
    1. Click the Keychat icon in your toolbar — the side panel opens
    2. Connect your wallet (MetaMask, Coinbase, or WalletConnect)
    3. Sign one message to create your XMTP identity (one-time)
    4. Paste any wallet address to start a chat
    5. Send messages, reactions, replies, edits — all end-to-end encrypted
  
    ━━━━━━━━━━━━━━━━━━━━━━━━━
    SECURITY HIGHLIGHTS
    ━━━━━━━━━━━━━━━━━━━━━━━━━
  
    • Forward secrecy — past messages stay protected even if a key is later stolen
    • Post-compromise security — rotate your wallet to restore end-to-end protection
    • Block at the protocol level (not just a UI filter)
    • New senders land in a Requests inbox — no notification spam
    • Group chats coming soon, with the same MLS guarantees
