Feather is a Monero wallet with a graphical interface similar to that of Electrum.

To learn how to use Feather in Tails, see XMRGuide: Setting up Feather on Tails.

If you follow the guide linked to above, you will install Feather as an AppImage instead of using the Additional Software feature. This is because Feather is not included in Debian.

Because Feather is not included in Debian, it does not receive the same high level of scrutiny as software in Debian. This makes it much more likely for a security issue in Feather to go undiscovered.

Also, because Feather is not being installed using the Additional Software feature, it will not be automatically updated.

Please report your findings about using Feather in Tails on #17823.
