Factory contract for deploying Ion Lending Vaults.

### [Functions](https://docs.ionprotocol.io/devs/smart-contract-architecture/vault/broken-reference) <a href="#functions" id="functions"></a>

#### [createVault](https://docs.ionprotocol.io/devs/smart-contract-architecture/vault/broken-reference) <a href="#createvault" id="createvault"></a>

Deploys a new Ion Lending Vault. Transfers the `initialDeposit` amount of the base asset from the caller initiate the first deposit to the vault. The minimum `initialDeposit` is 1e3. If less, this call would underflow as it will always burn 1e3 shares of the total shares minted to defend against inflation attacks.

*The 1e3 initial deposit amount was chosen to defend against inflation attacks, referencing the UniV2 LP token implementation.*

```
function createVault(
    IERC20 baseAsset,
    address feeRecipient,
    uint256 feePercentage,
    string memory name,
    string memory symbol,
    uint48 initialDelay,
    address initialDefaultAdmin,
    bytes32 salt,
    Vault.MarketsArgs memory marketsArgs,
    uint256 initialDeposit
)
    external
    returns (Vault vault);
```
