PoolAddressesProvider#Copy

The PoolAddressesProvider contract is the main registry of addresses that are part of, or connected to the Protocol, including permissioned roles. It acts as a factory of proxies and is the admin of those, and therefore has the right to change its implementations.

The addresses provider manages various protocol modules and has the ability to update pointers (e.g. update the ACLManager contract) or update the implementation of proxy contracts (e.g. update the Pool implementation).

It specifies the initial holder of the DEFAULT_ADMIN_ROLE, it is immutable, and the address will never change.

The source code is available on GitHub.

function setMarketId(string memory newMarketId) external override onlyOwner

Updates the identifier of the Aave market by associating an id with a specific PoolAddressesProvider. This can be used to create an on-chain registry of pool addresses providers to identify and validate multiple Aave markets.

function setAddress(bytes32 id, address newAddress) external override onlyOwner

Sets the address of the protocol contract stored at the given id, replacing the address saved in the addresses map.

For example, utils.keccak256(utils.toUtf8Bytes("INCENTIVES_CONTROLLER")), is set to the address of INCENTIVES_CONTROLLER.

function setAddressAsProxy(bytes32 id, address newImplementationAddress) external override onlyOwner

Updates the implementation address of a proxy contract with a specified id.

If there is no proxy registered, it will instantiate one and set the implementation as the newImplementationAddress.

function setPoolImpl(address newPoolImpl) external override onlyOwner

Updates the implementation of the Pool contract, or creates a proxy.

function setPoolConfiguratorImpl(address newPoolConfiguratorImpl) external override onlyOwner

Updates the implementation of the PoolConfigurator contract, or creates a proxy.

function setPriceOracle(address newPriceOracle) external override onlyOwner

Updates the address of the price oracle.

function setACLManager(address newAclManager) external override onlyOwner

Updates the address of the Access Control List Manager.

function setACLAdmin(address newAclAdmin) external override onlyOwner

Updates the address of the Access Control List Admin.

function setPriceOracleSentinel(address newPriceOracleSentinel) external override onlyOwner

Updates the address of the price oracle sentinel.

function setPoolDataProvider(address newDataProvider) external override onlyOwner

Updates the address of the data provider.

function getMarketId() external view override returns (string memory)

Returns the market id of the associated Aave market.

function getAddress(bytes32 id) public view override returns (address)

Returns the address of protocol contract stored at the given id. The returned address might be an EOA or a contract, which may be proxied. It will return ZERO if there is no registered address with the given id.

// Get address of incentive controllerimport { utils } from "@ethers/lib/utils";
const id = utils.keccak256(utils.toUtf8Bytes("INCENTIVES_CONTROLLER"));const address = poolAddressProvider.getAddress(id);

function getPool() external view override returns (address)

Returns the address of the latest Pool proxy contract.

function getPoolConfigurator() external view override returns (address)

Returns the address of the PoolConfigurator proxy. Used for configuration methods, like init reserves or update token implementation etc, of the market.

function getPriceOracle() external view override returns (address)

Returns the address of the Price Oracle used by the market.

function getACLManager() external view override returns (address)

Returns the address of the Access Control List Manager (ACLManager) that manages the system role of the market.

function getACLAdmin() external view override returns (address)

Returns the address of the Access Control List Admin (ACLAdmin) of the market which holds the DEFAULT_ADMIN_ROLE in ACLManager.

function getPriceOracleSentinel() external view override returns (address)

Returns the address of the price oracle sentinel.

function getPoolDataProvider() external view override returns (address)

Returns the address of latest pool data provider.
