AaveOracle
Contract to get asset prices, manage price sources and update the fallback oracle.
Protocol V3 uses Chainlink Aggregators as the source of all asset prices.
The fallback oracles from V1 and V2 of the protocol are now deprecated and no longer maintained.
function getAssetPrice(address asset)Returns the price of the supported
asset in BASE_CURRENCY of the Aave Market. All V3 markets use USD based oracles which return values with 8 decimals.Return Value
Type | Description |
|---|---|
uint256 | Price in BASE_CURRENCY of the Aave market. |
function getAssetsPrices(address[] calldata assets)Returns the prices of the supported
assets in BASE_CURRENCY of the Aave Market. All V3 markets use USD based oracles which return values with 8 decimals.Call Params
Name | Type | Description |
|---|---|---|
assets | address[] | The addresses of the assets for which price is being queried. |
Return Value
Type | Description |
|---|---|
uint256[] | Prices in BASE_CURRENCY of the Aave market. |
function getSourceOfAsset(address asset)Returns the address of the price source for
asset.function getFallbackOracle()Returns the address of the fallback oracle.
function setAssetSources(address[] calldata assets, address[] calldata sources)Sets the price source for given list of assets.
This method can be called only by
POOL_ADMIN or ASSET_LISTING_ADMIN. Check ACLManager for details on system roles.Call Params
Name | Type | Description |

assets | address[] | The addresses of the assets for which source is being set. |
sources | address[] | The address of the source of each asset. Length of assets and sources array should be same. |
function setFallbackOracle(address fallbackOracle)Sets/updates the fallback oracle.
