1\. Confirm Market Parameters

* loanToken
* collateralToken
* Oracle
* Irm
* lltv

| Parameter       | Type    | Description                              |
| --------------- | ------- | ---------------------------------------- |
| loanToken       | address | Contract address of the borrowing token  |
| collateralToken | address | Contract address of the collateral token |
| oracle          | address | Address of the oracle                    |
| irm             | address | Address of the interest model            |
| lltv            | uint256 | Loan-To-Value rate                       |

Note：

* Oracle: The oracle must implement the following method, where asset is the token address. The function should return the asset price with 8 decimals of precision:

function peek(address asset) external view returns (uint256);

* IRM (Interest Rate Model): This must be enabled by Lista Lending’s manager using enableIrm. By default, the protocol uses the IRM deployed by Lista Lending at the following address: \[TBD]
* LLTV (Loan-to-Value for Liquidation): This must also be set by Lista Lending’s manager using enableLltv. Users may choose from the enabled LLTV options to create a vault.<br>
