Whoever holds the keys
holds the messages.
No emails. No phone numbers. No central server that can read, delete, or surrender your conversations — and no future quantum computer that can break them.
5 chains · 1 inbox
Three steps. Zero accounts.
One signature with the wallet you already own — keys derive locally, never leave the device, then talk to any address on chain.

Keys derive locally
Your encryption keys derive in-browser from your wallet — wrapped in a hybrid X25519 + Kyber-1024 handshake. They never leave the device.

Talk to any address
Search by ENS or paste a wallet address. Inbox requests gate strangers. Group chats encrypt at every epoch.
Cryptography is the only contract
we sign.
Wallet-based identity, AES-256-GCM, MLS RFC 9420, Kyber-1024 and Dilithium3 — composed from open standards, never proprietary.

Frequently Asked Questions
Telegram founders get arrested. Meta quietly disables E2EE. Signal still wants your phone number. We started Keychat because none of those things are accidents — they are the architecture.
No. Messages are encrypted on your device with AES-256-GCM and wrapped in MLS (RFC 9420) before they ever leave your browser. Only you and your recipient hold the keys — relays only see ciphertext, and there is no Keychat server in the middle.
Not your keys, not your chats.
Take the key back. Start sending messages only you and your recipient can read — secured by AES-256-GCM, MLS RFC 9420, Kyber-1024 and Dilithium3.
