Navano

Navano is an opensource featherweight Nano wallet in your browser.

Nano is a fast & fee-less currency secured by a decentralised network. The Navano wallet stores all sensitive data locally (encrypted) and never communicates it to a server.

Navano injects a rudimentary Nano API into every website's javascript context, to allow some basic Nano dapps. For this reason it requires permission to read and write to any webpage. However, the injected code is only a few lines long, and you can read it here:

v0.0.3: fixes signing and improves the robustness of receiving transfers to new wallets.
