Analysing Blockchain Data
Similar to all Ethereum based smart contract protocols, all of Aave's data, transactions, and events are extractable directly from the blockchain. This section will describe the most common data that you may want to extract from Aave Protocol.
Ensure you are working with the latest smart contract addresses as detailed on the Deployed Contracts page.

Deposit

    is 1:1 pegged with the original asset (e.g. 1 aDAI === 1 DAI), and
    immediately earns interest.
