<summary>How many sub-wallet can I create?</summary>

<details>

<summary>Are the transactions of a sub-wallet private?</summary>

To the world these transactions are as private as any other bitcoin payment over the lightning network.\
For the Alby Hub operator all transactions are visible like for any other bank when you deposit your fiat money in a bank account.

<details>

<summary>Can a sub-wallet have a higher balance than the Alby Hub main lightning balance?</summary>

The total amount in the main Alby Hub lightning balance includes all sub-wallets, plus any funds not allocated to any sub-wallet and deposited directly.\
However, since sub-wallet are only an internal account system one could reduce the main Alby Hub lightning balance without reducing the balance of a sub-wallet resulting in a higher balance of the latter. In this case you'll see a warning that your lightning balance is too low to honor all balances of sub-wallets.

<summary>If I created a wallet for an artist friend, but then he or I deleted that connection? Would their Alby account continue to work?</summary>

Yes. The Alby account remains active but they cannot send payments anymore. You will have to create a new sub-wallet and share the "Connection Secret" with your artist friend.

<summary>How to restore a sub-wallet if the user deletes it?</summary>

If the Alby Hub owner or the user have saved the sub-wallet-specific "Connection Secret", it can be reused. For security and convenience, we recommend using a password manager to store the sub-wallet-specific "Connection Secret."\
Note: Your sats are still part of the main Alby Hub lightning balance and not lost after deletion of any sub-wallet.

<summary>How can I create a sub-wallet with a starting balance</summary>

Right after adding a name and clicking on "Create sub-wallet", you can scroll to the bottom where you see the option to add a starting balance.\
Please note: Funds are not transferred over the network but are simply associated with the sub-wallet. As a result, no transaction fees are incurred.

<details>

<summary>How do I transfer sats to a sub-wallet?</summary>

After the sub-wallet was created, the sub-wallet appears on the "Connection" page of your Alby Hub. If you open this sub-wallet, you'll see a "Top Up" button to increase its balance, using funds from the main Alby Hub lightning balance.
