# retired: A hardware wallet is one more device to trust and keep. For most people the safer,
# simpler thing is to write the seed words on paper or metal and back them up on an encrypted
# USB stick (usb mount unlocks LUKS). The wallets it paired with (Sparrow, Electrum, Feather)
# are retired from the desktop too; Whonix has Electrum and Feather behind Tor.
# What is left of this extra is its --remove, for whoever still has it set up: update.sh offers
# it, and so does wrenctl remove hardware-wallet. It can't be installed any more.
# Usage: bash hardware-wallet.sh --remove
# summary: Hardware wallets over USB (Trezor, Ledger...)
# security: most
# category: money
# status: file:/etc/udev/rules.d/60-wren-hardware-wallets.rules
