Damn Vulnerable DeFi V3?2023

Damn Vulnerable DeFi V3 (DVD V3) is a collection of smart contracts designed to simulate a war game environment for learning offensive security of DeFi smart contracts. Unlike theoretical exercises, DVD provides a more realistic experience by allowing participants to interact with smart contracts that resemble real DeFi protocols.

Key Features and Challenges

The DVD V3 challenge incorporates 15 exercises, each representing a different vulnerable smart contract. These exercises cover a wide range of attack vectors, including flash loans, price oracles manipulation, governance attacks, NFTs, DEXs, and lending protocols. Participants need to find vulnerabilities in the contracts and exploit them to complete the exercises successfully.

Getting Started with Damn Vulnerable DeFi?V3

To start solving DVD V3, you’ll need to clone the challenge’s repository and set up the environment. The challenge employs the Hardhat framework, written in Solidity programming language for the smart contracts, and JavaScript for the test files that trigger transactions and set the state.

Execute the following commands:

git clone https://github.com/tinchoabbate/damn-vulnerable-defi/tree/v3.0.0

cd damn-vulnerable-defi

yarn install        

Navigating the Repository Folder Structure

The DVD V3 repository is a Hardhat project and it consists of multiple files and folders. While the most important folders are the contracts and test folders.?

Each exercise has its own folder containing the vulnerable smart contracts that participants will attempt to hack same goes to the test folder which contains subfodlers for every challenge in the CTF.?

Additionally, there is a “player contracts” folder where users can deploy their malicious smart contracts to interact with the vulnerable ones.

Tips for?Success

Mastering Damn Vulnerable DeFi V3 2023 requires a strategic approach and a keen eye for vulnerabilities. Here are some valuable tips to enhance your chances of success:

1. Careful Reading: Begin each exercise by thoroughly reading the instructions. Understand the objectives and the expected outcomes. Take note of any specific hints or clues provided in the exercise description.
2. Smart Contract: Dive into the smart contract code for the exercise. Analyze the logic, functions, and interactions within the contract. Look for potential security loopholes or areas where user inputs might not be adequately validated.
3. Leveraging Special Comments: In the contracts, utilize special comments to mark your observations, potential vulnerabilities, or exploit ideas. These comments act as useful references while working through the exercise and help maintain a structured approach.
4. Test File Examination: Explore the test files to understand the initial state of the system and the sequence of transactions being executed. This insight will aid in crafting an effective strategy to manipulate the contract’s behavior and achieve the desired objectives.
5. Persistence and Experimentation: Solving challenging exercises may require perseverance and experimentation. Don’t get discouraged if you encounter obstacles along the way. Keep experimenting with different approaches until you find a viable solution.
6. Take Breaks: Smart contract hacking can be mentally taxing. If you find yourself stuck or hitting a mental block, take breaks to refresh your mind. Stepping away from the challenge and returning with a fresh perspective often leads to breakthroughs.
7. Watch Walkthrough Videos: If you feel stuck and need guidance, consider watching walkthrough videos which I constantly post on my Youtube Channel. These videos provide valuable insights into solving the exercises and can offer new perspectives on problem-solving.
