Welcome, aspiring security auditors and bug hunters! The Damn Vulnerable DeFi wargame is your playground to build skills for offensive security of DeFi smart contracts. Through numerous challenges, you’ll learn to navigate the nitty-gritty of security and exploit vulnerabilities like a pro. Let’s dive in and unravel how to set up and embark on this enlightening journey!

Step-by-Step Guide to Get Started

1. Install Foundry

The first step is to install the Foundry toolchain. Run the following command:

bash
curl -L https://foundry.paradigm.xyz | bash

After installation, in a new terminal session or after reloading your PATH, run the command below to get the latest forge and cast binaries:

foundryup

2. Clone the Repository and Install Dependencies

Next, clone the game repository and navigate into it:

git clone https://github.com/nicolasgarcia214/damn-vulnerable-defi-foundry.git
cd damn-vulnerable-defi-foundry
forge install

3. Code Your Solutions

In the `test` folder, you will find individual folders for each level. Work on the provided `NAME_OF_THE_LEVEL.t.sol` files to outline your solutions. Each level is like a puzzle waiting to be solved!

4. Run Your Exploit for a Challenge

To test your creations and see if you’ve successfully exploited a vulnerability, execute:

make [CONTRACT_LEVEL_NAME]
or
./run.sh [LEVEL_FOLDER_NAME]/run.sh [CHALLENGE_NUMBER].run.sh [4_FIRST_LETTER_OF_NAME]

Success! If the challenge runs successfully, congratulations, you have passed!

Tips and Tricks for a Smoother Experience

• When tackling challenges, always use the account called attacker.
• Leverage cheat codes such as prank or startPrank for some quick tweaks.
• Don’t hesitate to explore the Foundry Book for reference while coding your solutions.
• In certain cases, you may have to develop and deploy custom smart contracts for optimal results.

Troubleshooting Tips

In case you encounter issues during setup or challenges, here are a few suggestions:

• Ensure your terminal is up-to-date and that you’ve reloaded your PATH after installing Foundry.
• If cloning the repo fails, double-check the URL for any typos.
• For installation problems, including dependencies, restart the process to ensure all configurations are set correctly.
• If you’re stuck on a challenge, refer to previous levels and examples in the Foundry Book for guidance.
