The Aave protocol leverages the Graph Protocol Network to host its subgraphs, which provide a streamlined GraphQL API endpoint for accessing indexed data from Aave smart contracts. By utilizing the Aave Subgraphs, developers gain the ability to monitor on-chain actions such as borrows, deposits, collateral ratios, and more. These valuable insights empower the creation of decentralized applications that analyze and report on both individual and market-level activities. Moreover, developers can efficiently extract the required information without delving deep into the internal protocol implementation.
