E2E · no identifiers · no plaintext
Talk privately.
Leave less behind.
Designed so the network learns as little as practically possible about who you are, who you talk to, and what you say.

Keys made on your device
Your identity is a 12-word phrase. It never leaves your device.
End-to-end encrypted
The server stores only scrambled data it cannot read.
No phone, no email
No sign-up form, no KYC, no wallet connection required.
Disappearing messages
Set a timer per chat: 1 hour, 24 hours or 7 days.
Invite by link or QR
One-time links for private chats, reusable links for groups.
Private groups
Each message is locked separately for every member.
Honest note: no app can promise perfect anonymity. A compromised device, malware, or your own sharing can still reveal things. BlockChat keeps what the service learns to a minimum.
