# ReservesSetupHelper

{% hint style="info" %}
This contract is a **helper tool** for configuring multiple reserves in one call, instead of manually calling the PoolConfigurator asset by asset. It streamlines the process of setting **caps, LTV, liquidation parameters, borrowing rules, and flash loan support**.
{% endhint %}

#### Functions

* **configureReserves(PoolConfigurator configurator, ConfigureReserveInput\[] inputParams)** Sets up or updates the configuration of reserves in the protocol through the `PoolConfigurator`.
  * `configurator`: The PoolConfigurator contract that manages protocol reserve settings.
  * `inputParams`: Array of configuration objects containing:
    * `asset`: Address of the reserve (e.g., DAI, USDC).
    * `baseLTV`: Loan-to-Value ratio (how much can be borrowed against collateral).
    * `liquidationThreshold`: Percentage threshold before liquidation occurs.
    * `liquidationBonus`: Bonus given to liquidators.
    * `reserveFactor`: Portion of interest redirected to the protocol.
    * `borrowCap`: Maximum borrow limit.
    * `supplyCap`: Maximum supply limit.
    * `stableBorrowingEnabled`: If stable rate borrowing is allowed.
    * `borrowingEnabled`: If borrowing is enabled at all.
    * `flashLoanEnabled`: If flash loans are enabled for this asset.

***

* **owner() → address** Returns the current owner (admin) of the helper contract.
* **renounceOwnership()** Allows the current owner to give up control of the contract.
* **transferOwnership(address newOwner)** Transfers contract ownership to `newOwner`.

***

**Events**

* **OwnershipTransferred(previousOwner, newOwner)** Triggered when ownership of the contract is moved from one address to another.
