If you've deleted the Monolith app from your phone, your Contract Wallet is no longer paired with your device. This means that your private key will be automatically removed from your device’s storage.
You will need your Seed to reactivate both the app and your Contract Wallet. Please keep your Seed somewhere safe (not on your device, in case your device is lost or stolen). Monolith never sees your Seed, or keeps a copy of it, therefore we will not be able to assist if you lose it.
You can reinstall the app on your device by downloading the Monolith app from the iOS/Android App store and selecting ‘Recover Existing Seed’ during the signup process.
