AAVE is a decentralized lending platform built on the Ethereum blockchain. It allows users to lend, borrow, and earn interest on various cryptocurrencies without a centralized authority.

The platform operates through smart contracts, which are self-executing agreements that automatically enforce the terms of the contract. AAVE's smart contracts are designed to facilitate peer-to-peer lending by connecting lenders and borrowers directly, and the supply and demand for each asset determine the interest rates.

AAVE also has a unique feature called "flash loans," which allows users to borrow funds without collateral for a brief period of time (usually less than a second). Developers have used this feature to build new decentralized finance (DeFi) applications and arbitrage opportunities.

Overall, AAVE is a critical player in the DeFi ecosystem and has helped to make decentralized lending more accessible and efficient for users.

Used SQL queries that extract data from tables in a database related to the Aave protocol on the Ethereum blockchain. The tables used in the queries are "ez_deposits", "ez_withdraws", "ez_borrows", and "ez_repayments". The queries follow a similar structure but differ in the fields and tables they select from. Each query groups the results by day and provides metrics such as the number of transactions, unique users, and the total USD value of the transactions. The fields selected include the date of the transactions, the unique transaction hash, the user addresses, and the amounts involved. The queries also compute additional metrics such as the average, minimum, maximum, and median amounts involved in the transactions. All queries have a filter on the block timestamp field, limiting the results to transactions that occurred on or after January 1, 2023.
