Big thanks to Tincho who created the first version of this game and to all the fellows behind the Foundry Framework

Damn Vulnerable DeFi is the wargame to learn offensive security of DeFi smart contracts.

Throughout numerous challenges you will build the skills to become a bug hunter or security auditor in the space. 🕵️‍♂️

1. Install Foundry

First run the command below to get foundryup, the Foundry toolchain installer:

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

Then, in a new terminal session or after reloading your PATH, run it to get the latest forge and cast binaries:

foundryup

2. Clone This Repo and install dependencies

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

3. Code your solutions in the provided [NAME_OF_THE_LEVEL].t.sol files (inside each level's folder in the test folder)
4. Run your exploit for a challenge

make [CONTRACT_LEVEL_NAME]

or

./run.sh [LEVEL_FOLDER_NAME]
./run.sh [CHALLENGE_NUMBER]
./run.sh [4_FIRST_LETTER_OF_NAME] 

If the challenge is executed successfully, you've passed!🙌🙌

• In all challenges you must use the account called attacker. In Forge, you can use the cheat code prank or startPrank.
• To code the solutions, you may need to refer to the Foundry Book.
• In some cases, you may need to code and deploy custom smart contracts.

ds-test for testing, forge-std for better cheatcode UX, and openzeppelin-contracts for contract implementations.
