This repository hosts a TCP server, which is primarily used for the deployment of CTF challenges related to Ethereum smart contracts.
You will find in this repository several folders:
/challengescontaining web3 challenges. Each challenge contains a .sol file with abi and bin version. A .yaml file containing the details of the challenge. And a py file containing the check to do to validate the challenges. All of these challenges are listed in the challenges.yaml file at the root of the repo./py_servercontains all the logic of the TCP server.
ps: you can run the docker-compose file to not bother with the following setup.
Create a .env with the following content at the root of the repository

Run a docker container to host a private node using anvil
docker run -d -p 8545:8545 ghcr.io/foundry-rs/foundry:latest anvil
Run the software
python3 pip3 install -r requirements.txt
python3 main.py
Once the server is started, you can query it via the nc command. A menu is then available and allows you to list the challenges, retrieve the source code, deploy etc..
