Acknowledgement

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. 🕵️‍♂️

How To Play 🕹️

  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

Advanced ways to use foundryup, and other documentation, can be found in the foundryup package

  1. Clone This Repo and install dependencies
git clone https://github.com/nicolasgarcia214/damn-vulnerable-defi-foundry.git
cd damn-vulnerable-defi-foundry
forge install
  1. Code your solutions in the provided [NAME_OF_THE_LEVEL].t.sol files (inside each level's folder in the test folder)
  2. 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!🙌🙌

Tips and tricks ✨

  • 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 Forge docs.
  • In some cases, you may need to code and deploy custom smart contracts.

Preinstalled dependencies

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