## Functions

### getMarketId

| `newMarketId` | `string` | The new market identifier. |

### getAddress

Fetches an address associated with a given identifier.

*Can return either a direct contract address or a proxy address.*

*Returns address(0) if no address is registered with the given identifier.*

```solidity
function getAddress(bytes32 id) external view returns (address);
```

**Parameters**

### setAddressAsProxy

Updates or initializes a proxy for a given identifier with a new implementation address.

*Use with caution for identifiers without dedicated setter functions to prevent unintended effects.*

*Only use for identifiers POOL\_CONFIGURATOR, LOAN\_MANAGER, WITHDRAWAL\_MANAGER, or ISLE\_GLOBALS.*

```solidity
function setAddressAsProxy(bytes32 id, address newImplementationAddress, bytes calldata params) external;
```

**Parameters**

| Name                       | Type      | Description                                           |
