The Aave Protocol V3 repository, now deprecated and no longer maintained, originally contained the smart contracts source code and market configurations for Aave’s decentralized liquidity markets protocol. Designed for developers, it utilized Docker Compose and Hardhat for environment setup, compilation, testing, and deployment. Aave facilitates non-custodial liquidity, allowing users to act as suppliers for passive income or borrowers in either overcollateralized or undercollateralized formats. While the repository includes audit reports from firms like PeckShield and SigmaPrime, ongoing community interaction is encouraged via Discord and the Governance Forum. Developers can integrate Aave V3 functionalities within Hardhat or Truffle projects by installing the “@aave/core-v3” NPM package and utilizing the provided ABI and Bytecode artifacts in JSON format. The setup requires Docker, configuring environment variables for providers like Alchemy or Infura, and optionally, Tenderly scripts. Despite the deprecation, detailed documentation remains available to support transitioning efforts to the latest V3 Origin Repository.
