Sphinx Chat

Sphinx Chat is a decentralized messaging and social media platform built on the Bitcoin Lightning Network. It provides end-to-end encrypted chat without relying on central servers, allowing messages to be transmitted directly over Lightning infrastructure rather than through corporate data collection points. This architecture is designed so that users cannot be deplatformed by a central authority and retain control over their own data.

The platform integrates Bitcoin payments directly into messaging, enabling users to send and receive satoshis instantly to anyone globally. It supports paywalls for selling images, videos, and other content, allowing creators to monetize directly with their audience without advertising. Payments can also be attached to media such as memes within conversations.

Sphinx Chat serves individuals and content creators seeking privacy-preserving communication combined with built-in monetization, as well as users interested in alternatives to centralized social media platforms. It connects to self-hosted or third-party Lightning nodes, including Greenlight, Umbrel, RaspiBlitz, and myNode, giving users choice over their backend infrastructure. The app is positioned within the broader Bitcoin and Lightning Network ecosystem as a tool for rearchitecting internet communication around user-owned data and peer-to-peer value transfer.
