Methmine™ VPN — Open Source Notices
Last updated: October 15, 2026
The Methmine VPN apps are built with open source software. We are grateful to its authors. This page lists the components that ship in the apps and the licenses they are distributed under. Each component is governed by its own license, which prevails over our Terms for that component (Product Schedule 13.4). The full license texts are also included in the apps, under Support → Open source licenses.
The list was generated from the apps' dependency manifests. Where we could not confirm a license from the component's own license file, it says so.
Tunnel core
| Component | License | Notes |
|---|---|---|
| Xray-core v26.9.9 | MPL-2.0 | The VPN core in every app. We build it from a copy of the upstream release with one change: the Shadowsocks configuration files (infra/conf/shadowsocks.go and its registration) are removed. No other file is modified. |
| REALITY | MPL-2.0 | Part of the Xray-core build. |
Source code for MPL-2.0 components. The Source Code Form of Xray-core and REALITY is available from their upstream repositories linked above. The exact source of the copy we build, including our one change, is available on request: write to contact@methmine.com with the subject "Legal notice", and we will provide it at no charge beyond the cost of delivery.
