The Degens Vault allows you to split your gaming balances & requires a password to unlock for increased security.
The vault is a separate balance from your wallet balance. When you transfer funds into your vault, it will not be used for games. This allows users to separate their gaming balances.
You can find the Vault by heading to your Profile and revealing the options.
You can transfer between your wallet and vault as often as you wish. You can also check the vault transfer history here.
Note you will have to re-enter your password to transfer out of the vault.
