Aave V2 Liquidation Example

This repo demostrates how a liquidation strategy works on Aave V2 Ethereum Mainnet using foundry.

Installation and Setup

1. Install foundry, if you haven't already.

2. Clone This Repo

Run the following command.

git clone https://github.com/yuichiroaoki/aaveV2-liquidation-example.git

Demo

1. Get Ethereum Mainnet RPC URL

You can get one from Alchemy website for free.

2. Compile Smart Contracts

Run the following command.

forge build

3. Execute a Liquidation Call 🔥

Replace <your alchemy rpc url> with the Ethereum Mainnet RPC URL you get from step 1 and run the following command. This will run test/Liquidation.t.sol, a test contract for src/Liquidation.sol on the Ethereum Mainnet fork network on your local machine.

forge test -vv --fork-url <your alchemy rpc url> --fork-block-number 15780157 --mp test/Liquidation.t.sol
