Kursal-style Decentralized Encrypted Messenger Starter Kit

Help developers quickly build E2E encrypted messaging apps with libp2p and Signal protocols

Problem

Indie developers are interested in decentralized, quantum-resistant communication apps, but implementing libp2p networking, Double Ratchet, and PQXDH from scratch is extremely difficult and takes months. They need a reliable starter template to skip the low-level complexity.

Solution

An open-source template that encapsulates libp2p peer discovery, Double Ratchet encryption, and PQXDH key exchange, letting developers focus on application-layer features (groups, file transfer, UI). It includes a Rust backend and simple client examples with detailed docs.

Users

Indie developers with some Rust or systems programming experience who are interested in private communication.

MVP

Libp2p-based peer discovery and connection; Double Ratchet encrypted messaging; PQXDH key exchange; CLI or simple UI example; one-click Docker deployment.

Revenue

Open-source core free; paid enterprise support, custom development, or hosted relay service.

Why now

Privacy and quantum-resistant encryption are gaining attention, and projects like Kursal already prove technical feasibility. Indie developers can build a template on mature components to lower the barrier for newcomers.
