A Seed is a collection of 12 words you need to recover your Contract Wallet. These words were auto-generated when you set up your Monolith account. If you’ve lost these words, you can retrieve them by going to the 'Wallet' tab > 'Security' sub-tab (next to Balances) > 'Wallet Backed Up' 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. You should never share your seed with anyone. Monolith does not ever see your Seed, or keep a copy of it. We, therefore, will not be able to recover your account if you lose it.
