# 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](https://book.getfoundry.sh/getting-started/installation), if you haven't already.
### 2. Clone This Repo
Run the following command.
```console
git clone https://github.com/yuichiroaoki/aaveV2-liquidation-example.git
```
## Demo
### 1. Get Ethereum Mainnet RPC URL
You can get one from [Alchemy website](https://alchemy.com/?r=33851811-6ecf-40c3-a36d-d0452dda8634) for free.
### 2. Compile Smart Contracts
Run the following command.
```console
forge build
```
### 3. Execute a Liquidation Call 🔥
Replace `` 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.
```bash
forge test -vv --fork-url --fork-block-number 15780157 --mp test/Liquidation.t.sol
```
Expected Outputs
```
