Warren VPN Beta

Welcome to the Warren VPN client app source code repository.

Warren VPN is a fork of the Mullvad VPN app (GPL-3.0, Mullvad VPN AB). This repository preserves the complete upstream git history, back to 2016, with original authorship intact. It is standalone rather than a GitHub-native fork: the project started in a private repository, GitHub does not allow a private fork of a public repository, and a repository cannot join a fork network after creation. The upstream remote stays wired: security and correctness fixes in the platform layers (routing, DNS, firewall, split tunneling, leak checker) are cherry-picked from upstream, per docs/UPSTREAM-DETACH.md.

Warren VPN carries traffic over a QUIC tunnel and identifies its users by a non-custodial wallet. One Ed25519 key, derived from a BIP39 mnemonic that never leaves the device, authenticates the tunnel's TLS handshake to the exit and signs every request to the Warren backend, which serves accounts, subscriptions and devices. There is no account number and no bearer token. The backend host follows the build channel (api.beta.warrenbrowse.com for the beta builds shipped today).
