Cloud Sync

Cloud Sync

Avana Wallet enables you to backup your encrypted account data to the cloud, which helps you restore your account if you ever lose your device. Self-custody wallets provide you a lot of freedom and autonomy, but that also means that if you lose your device and do not have all of your backup phrases you could lose your accounts too.

There are countless stories of people losing their funds after their devices are misplaced. One man in the United Kingdom lost over 400 million dollars in Bitcoin after his girlfriend tossed his laptop.

Cloud Sync acts like a "password manager" where you just need one account - your Avana Wallet account - to restore all of your crypto accounts. Your Avana Wallet account encrypts your wallet data and then sends it to the cloud to store in an encrypted database. This feature is helpful when you have many accounts.

The cloud storage is very secure. We implement two layers of encryption (your encrypted data is wrapped in second layer of encryption):

  1. Your wallet data on your device is encrypted using your Avana Wallet account secret. Only you have access to this secret, and only your Avana Wallet account key can decrypt it. This encryption is the same that protects major blockchains such as Solana and Ethereum. Avana Wallet has no way to unencrypt or access the unencrypted data when it is sent to the cloud.
  2. Your encrypted data is then wrapped with another layer of encryption using Avana's keys when it is stored in the cloud.

Actual Encrypted Data Example

Below is an example of one of our developer's encrypted data stored in Cloud Sync. As you can see, the data are impossible to read and decipher without the decryption keys.

This form of encryption is commonly referred to as "military-grade encryption", which is used by organizations seeking the highest level of data security.

Lost Secret = Lost Wallet

Avana Wallet has no way to restore or unencrypt your Cloud Sync data if you lose your account secret key. Make sure you keep a record of your secret key in a safe location

Enabling Cloud Sync

You can enable Cloud Sync by going to Account Settings → Cloud Sync, then toggle the switch on. Cloud Sync will make an initial backup of your data when you enable it.

Disabling Cloud Sync

You can disable Cloud Sync at any time. Simply toggle the switch to disabled. Your stored data will remain on the cloud when Cloud Sync is disabled.

You can delete all of your data from the cloud by clicking on the "Delete Data" button. This action is permanent.

Restoring Data

Restore your Avana Wallet from a Cloud Sync snapshot by clicking on the snapshot version, then click "Restore" button. Restoring a prior snapshot will overwrite all of your current data.
