# Compax

> An end-to-end encrypted group messenger with a multi-chain wallet built into
> it. A group holds money together with a multisig on the chain it is on, and
> the conversation about that money is in the same thread as the money.

Compax is free and its source is public. The delivery service, the Bot API
gateway and the clients are in one repository and can be run by anybody.

## What it is

- Messaging: end-to-end encrypted with MLS (RFC 9420). The server carries
  ciphertext it cannot read.
- Wallet: Bitcoin, Ethereum, BNB Smart Chain, Tron and Solana, with each
  chain's own multisig rather than one written by us.
- Groups: a shared wallet needs the signatures the group set — any 3 of 5,
  any 2 of 3 — and the keys stay on the members' own devices.
- Bots: the Telegram Bot API shapes, against a gateway of ours, plus native
  widgets a bot can draw in a chat.
- Self-hosting: one image, one compose file, two instances by default.
