A Seed is a collection of 12 words you need to recover your Contract Wallet. These words were auto-generated when you set up the TokenCard app. If you’ve lost these words you can retrieve them by going to 'More page'> ‘Backup Seed in the app. Please keep a hard copy 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 the app and your Contract Wallet. TokenCard does not ever see your Seed or keep a copy of it therefore we will not be able to assist if you lose it.
