# PoolAddressesProvider

The `PoolAddressesProvider` contract is the main registry of addresses that are part of or connected to the Fathom protocol, including permissioned roles. It acts as a factory of proxies and an admin of those proxies, with the right to change their implementations. The contract is owned by the Fathom Governance.

### **Storage Variables**

* **\_marketId**: The identifier of the Fathom Market.
* **\_addresses**: A mapping of registered addresses (`bytes32 identifier` => `address registeredAddress`).

### **Constants**

* **POOL**: The identifier for the pool address.
* **POOL\_CONFIGURATOR**: The identifier for the pool configurator address.
* **PRICE\_ORACLE**: The identifier for the price oracle address.
* **ACL\_MANAGER**: The identifier for the ACL manager address.
* **ACL\_ADMIN**: The identifier for the ACL admin address.
* **PRICE\_ORACLE\_SENTINEL**: The identifier for the price oracle sentinel address.
* **DATA\_PROVIDER**: The identifier for the data provider address.

* **getPoolConfigurator()**: Returns the address of the pool configurator.
* **getPriceOracle()**: Returns the address of the price oracle.
* **getACLManager()**: Returns the address of the ACL manager.
* **getACLAdmin()**: Returns the address of the ACL admin.
* **getPriceOracleSentinel()**: Returns the address of the price oracle sentinel.
* **getPoolDataProvider()**: Returns the address of the pool data provider.
