Pacto

Pacto is a community messaging and governance tool that offers end-to-end encrypted chat, on-chain proposals and voting, and a shared treasury without middlemen holding the keys. Its site says it is built so no one can read members' messages, freeze their funds, or shut down the group. Encryption is described as the default rather than an optional mode, and group decisions are recorded on chain so outcomes are durable and hard to rewrite. The tool is described as live on macOS, Linux, and Windows, with source code also available to build.
