Chat

Private chat and calls for people with keys.

Chat is a pseudonymous messaging, video call, and coordination surface for users who enter with Bitcoin/Nostr-style cryptographic identity instead of real-name accounts.

How it works

Chat is not just messages. It is presence, calls, and coordination.

HODLXXI /app is the live surface where identity, presence, messages, video calls, small group calls, reputation signals, and optional Bitcoin-native context can meet.

Enter with key

You enter through HODLXXI by proving control of a key, not by receiving a platform account.

→

Become present

Your session becomes a presence signal: online, available, ready to coordinate.

→

Talk or call privately

Use the app as a communication surface for pseudonymous users, trusted contacts, and direct calls.

→

Coordinate in groups

Move from chat and calls into requests, appointments, attestations, receipts, and agreements.

For anonymous users

Talk and coordinate without turning your real name, phone number, or corporate login into your identity.

For cypherpunk groups

Use presence and key-owned identity instead of Discord-style accounts and surveillance social graphs.

Video calls and group calls

Start direct video calls or small group calls with up to 4 users, without turning the chat app into a real-name social network.

For Bitcoin users

Bring identity, chat, calls, and optional Bitcoin/Lightning context into one coordination surface.

For agents

Let humans and agents coordinate through keys, capabilities, signed requests, signed receipts, and reputation.

Live HODLXXI runtime

The chat app is backed by a live identity runtime.

The public status endpoint exposes online users, active sockets, Bitcoin height, Lightning status, and runtime uptime.

Security boundary

Chat should never ask for your seed phrase, private key, macaroon, wallet password, or secret token. You enter by proving control of a key. Your secrets stay on your device.

No. This page is about the chat app. Identity is key-owned and handled by the HODLXXI runtime.

Why does /app send me to login?
