Notes 
Wide range of features but a highly experimental protocol, use with caution.

Hardened
A hardened pick. Worth the effort once you have chosen to shrink your footprint on purpose. Enough for most people. Threat levels
Our take
The protocol carries its own warning label, and you should take it seriously: experimental means no security guarantees you can lean on. Treat Tox as a tinkerer’s project to explore, not the messenger you trust with anything sensitive. If you need real protection today, a maintained app with an audited protocol is the responsible choice.
