To log out of the app please select the ‘Unlink’ option on Monolith. You will need your Seed to unlink your account.
Please keep a backup of your Seed somewhere safe (not on your device, in case your device is lost or stolen). You will need your Seed to reactivate both Monolith and your Contract Wallet. Monolith never sees your Seed nor keeps a copy of it, therefore we will not be able to assist if you lose it.
