# MIMORebalance :::warning You're reading the legacy **v2** documentation. For current Parallel features, see [v3](/products/parallel-v3). ::: The `MIMOLeverage` action contract handle the super vault empty vault logic described in [Rebalancing](/products/parallel-v2/how-it-works/super-vaults-sv/rebalancing).

### Write Methods #### `executeAction(bytes calldata _calldata) external` Uses a flash loan to repay all debts for a vault and send all collateral in the vault to the owner. Requirements : * Contract must be unpaused * Must be called through the `MIMOProxy` `execute()` function * Targeted vault must have been created by the `MIMOProxy` | Param Name | Type | Description | | ---------- | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | \_callData | bytes |

Abi encoded bytes with :

FlashloanData flData
RebalanceData rbData
SwapData swapData

| **`RebalanceData`** | Param Name | Type | Description | | -------------- | ------- | --------------------------------------------------------------------------- | | `toCollateral` | IERC20 | Collateral to rebalance to | | `vaultId` | uint256 | Id of the vault to rebalance | | `mintAmount` | uint256 | Amount of stableX to mint on rebalancing vault to swap and repay flash loan | #### `executeOperation(address[] calldata assets, uint256[] calldata amounts, uint256[] calldata premiums, address initiator, bytes calldata params` AAVE `Pool` contract flash loan callback function. Requirements : * Contract must be unpaused * Can only be called by the AAVE `Pool` contract * Flash loan initiator must be the `MIMOProxy`

Param Name	Type	Description
`assets`	address\[]	Address array with one element corresponding to the address of the target vault asset
`amounts`	uint256\[]	Uint array with one element corresponding to the amount of the target vault asset
`premiums`	uint256\[]	Uint array with one element corresponding to the flashLoan fees
`initiator`	address	Initiator of the flashloan; can only be MIMOProxy owner
`params`	bytes	Bytes sent by this contract containing MIMOProxy owner, target vault id, SwapData struct

#### rebalanceOperation`(IERC20 fromCollateral, uint256 swapAmount, uint256 flashLoanRepayAmount, uint256 fee, RebalanceData calldata rbData, SwapData calldata swapData)` Performs a rebalance logic within MIMOProxy context. Requirements : * Contract must be unpaused * Contract must be unpaused * Must be called through the `MIMOProxy` `execute()` function | Param Name | Type | Description | | ---------------------- | ------- | ---------------------------------------------------------------------------------------------------------- | | `fromCollateral` | IERC20 | Collateral of the vault to rebalance | | `swapAmount` | uint256 | The amount of collateral to swap to for stableX to repay vaultdebt | | `flashLoanRepayAmount` | uint256 | Amount of collateral to repay to flash loan protocol at the end of the transaction | | `fee` | uint256 | Optional fee to be passed in the context of a `ManagedRebalance` to mint additional stablex to pay manager | | `rbData` | struct | `RebalanceData` passed from the flashloan call | | `swapData` | struct | SwapData passed from the flash loan call | ### View Methods `proxyFactory()` Returns the `MIMOProxyFactory` address.
