Casa Pay is a simple, lightweight wallet secured by a single key for either BTC or ETH.
Different than our multisig vaults, you don't need multiple keys to send funds when using Casa Pay. Pay allows you to sign and send transactions using just your mobile device.
Casa Pay makes storing a key on your mobile device (and backing it up) simple, safe, and easy, and it's available for all membership levels.
How is it backed up?
The Pay key is generated and stored within the secure enclave of your personal mobile device and backed up to your device's default cloud service. No need to write down a seed phrase!
If you're using an iPhone, Pay's key is backed up to iCloud. If you're using an Android phone, it is backed up to Google Drive.
In order for the Pay key to be backed up automatically, you need to be signed into your Apple (if you're using an iPhone) or Google (if you're using an Android phone) account in the system settings of your device.
You also have the option to back up your Pay key via QR code by following these instructions: QR Code Backups for Mobile and Pay Keys.
At no point does Casa ever have access to your key, and since the backup is encrypted, your cloud storage provider can't access your key either.
What if I get a new phone?
If you get a new phone and want to restore the Pay key, simply log into the Casa app on your new phone, and restore the key from backup. As long as you're signed in to the same Apple or Google account on the new phone as when you first set up the key, you're good to go.
