## What it is
Open source implementation of Aave Protocol Version 1.0, a decentralized lending pool system built on Ethereum smart contracts. This is the legacy V1 codebase of the production protocol, with audits from Trail of Bits and Open Zeppelin.

## Use cases
- integrate decentralized lending pools into a dapp
- study audited DeFi smart contract architecture
- build a crypto lending and borrowing protocol
- understand how Aave V1 flash loans and interest rates work
- audit or fork a legacy DeFi lending protocol

## When to choose
- you need to interact with or maintain Aave V1 on mainnet
- you want a real-world reference for audited lending pool contracts
- you're researching the evolution of DeFi protocol design

## When to avoid
- you want to build on the current Aave version - use the V2/V3 repos instead
- you need a general-purpose blockchain library rather than a specific protocol implementation
- you're not working with Ethereum smart contracts
