# IPoolAddressesProvider [Git Source](https://github.com/isle-labs/isle-contract/blob/main/contracts/interfaces/IPoolAddressesProvider.sol) Defines the basic interface for a Pool Addresses Provider. ## Functions ### getMarketId Retrieves the identifier of the Isle market associated with this contract. ```solidity function getMarketId() external view returns (string memory); ``` **Returns** | Name | Type | Description | | -------- | -------- | ----------------------------- | | `` | `string` | The identifier of the market. | ### setMarketId Links a new market identifier to this PoolAddressesProvider. *Useful for creating a registry of PoolAddressesProviders for multiple Isle markets.* ```solidity function setMarketId(string calldata newMarketId) external;
