Price Oracle

Throughout the Aave Protocol, we require reliable, up to date, and secure price feeds. Our proxy price provider contract provides this capability and works by:
Aave market
1.First checking for a price from a Chainlink aggregator.
2.If the price is below or equal to zero, we call our fallback price oracle.​
1.In the future, Aave governance mechanisms will manage the selection of sources and the fallback price oracle.
The source code can be found on the verified Etherscan contract.
If you need development support, join the #developers channel on our Aave community Discord server.
Always get the latest price oracle address by calling getPriceOracle() on the LendingPoolAddressProvider contract.
