 #### 16.3.4 Storage Provider Exit
 
 Storage providers can freely decide to exit, but SPs must complete a graceful exit to ensure no users are affected,

+otherwise, part of staked BNB from the SP will be slashed. Below are the key workflows about how SP exit:
 - The Storage Provider (SP1), initiates the exit process by submitting a `StorageProviderExit` transaction to the blockchain.
 - The SP1 or its successor SP must then repeatedly call `SwapOut` to remove itself from all Virtual Groups.
 - For the primary SP, the swap-out process occurs at the family level to ensure there are no conflicts with other SPs 
   within the Virtual Group.
 - For secondary SPs, the swap-out happens at the Virtual Group level and must also avoid conflicts with the primary SP.
