Welcome to the fantastic world of Capture the Flag (CTF) scenarios tailored for Ethereum Virtual Machines (EVM)! This guide will walk you through the steps to set up and use the WTF-CTF repository, enabling you to collect various CTFs and confidently tackle them using the Foundry framework.

Step 1: Setting Up Your Environment

Before jumping into the CTFs, you’ll need to set up your development environment. This involves installing the necessary tools like Rust and Foundry.

Install Rust

• Open your terminal.
• Run the following command to install Rust:

sh $ curl --proto =https --tlsv1.2 -sSf https://sh.rustup.rs | sh

Install Solidity Compiler Version Manager (SVM)

• Install with Cargo:

sh $ cargo install svm-rs

sh $ svm install 0.4.26

• Set the version for use:

sh $ svm use 0.4.26

• Check the version to ensure it’s installed correctly:

sh $ solc --version

Step 2: Clone the Repository

With Rust and SVM ready, you’re all set to clone the WTF-CTF repository. This contains various challenges you can take on.

• Clone the repository：

sh $ git clone https://github.com/WTFAcademy/WTF-CTF.git

• Navigate into the cloned directory：

sh $ cd WTF-CTF

Step 3: Install Dependencies

Next, install the various dependencies you need to complete the challenges.

sh $ forge install openzeppelin-contracts-05=OpenZeppelin:openzeppelin-contracts@v2.5.0 openzeppelin-contracts-06=OpenZeppelin:openzeppelin-contracts@v3.4.0 openzeppelin-contracts-08=OpenZeppelin:openzeppelin-contracts@v4.8.3

After installing the dependencies, run:

sh $ forge install

And then to perform the tests:

sh $ forge test --ffi -vvv

Step 4: Start Tackling CTF Challenges

Now you are ready to tackle the challenges available in the repository. Here’s a brief overview of the challenges:

• Capture the Ether:
  • Deploy a Contract
  • Guess the Number
• Ethernaut:
  • Hello Ethernaut
  • Coin Flip

Troubleshooting

If you run into issues during installation or while running tests, consider the following:

• Check your Rust installation by running rustc --version.
• Ensure you have the latest version of Foundry by visiting this link.
• If specific tests fail, consult the specific challenge’s README.md file.
