# MIMOEmptyVault

The `MIMOEmptyVault` action contracts handle the super vault empty vault logic described in [Empty Vault](/products/parallel-v2/how-it-works/super-vaults-sv/emptyvault.md).

### Write Methods

#### `executeAction(bytes calldata _calldata) external`

Uses a flashloan to repay all debts for a vault and send all collateral in the vault to the owner.

Requirements :&#x20;

* 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 | <p>Abi encoded bytes with : </p><ul><li><code>uint256 vaultId</code> </li><li><code>FlashloanData flData</code></li><li><code>SwapData swapData</code></li></ul> |

#### `executeOperation(address[] calldata assets, uint256[] calldata amounts, uint256[] calldata premiums, address initiator, bytes calldata params`

AAVE `Pool` contract flash loan callback function.

Requirements :&#x20;

* 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 |

#### `emptyVaultOperation(address owner, IERC20 vaultCollateral, uint256 vaultId, uint256 swapAmount, uint256 flashLoanRepayAmount, SwapData calldata swapData)`

Performs a empty vault logic within `MIMOProxy` context.

Requirements :&#x20;

* Contract must be unpaused
* Must be called through the `MIMOProxy` `execute()` function

| Param Name             | Type    | Description                                                                        |
| ---------------------- | ------- | ---------------------------------------------------------------------------------- |
| `owner`                | address | Address of the `MIMOProxy` owner                                                   |
| `vaultCollateral`      | IERC20  | Collateral of the vault to empty                                                   |
| `vaultId`              | uint256 | Vault id of the vault to be emptied                                                |
| `swapAmount`           | uint256 | Amount of collateral to swap to for par to repay vault debt                        |
| `flashLoanRepayAmount` | uint256 | Amount of collateral to repay to flash loan protocol at the end of the transaction |
| `swapData`             | struct  | SwapData passed from the flash loan call                                           |
