Running Cairo paradigm CTF solutions locally

This repository contains solutions for the Cairo challenges of the 2022 Paradigm-CTF

Creating env instructions

• create virtual environment

python3 -m venv ./venv
source ./venv/bin/activate

• Install requirements

pip install -requirements ./requirements.txt

• Run the server for deploying local environments

cd ./paradigm-ctf-infrastructure/images/cairo-challenge-base
python -m cairo_sandbox.server

Compiling the contracts

The compiled contrats have already been place in the correct direcotry.

Compiling the contrats from source:

Contracts can be compiled by running nile compile. This generates both the compiled contract files and abis in the artifacts dir

Although the generated files have a .json extension, the individual challenge scripts expect the file to be named .cairo

• Rename files to fit format: (for example)

mv artifacts/almost_erc20.json compiled/almost_erc20.cairo

Copy the files to the infrastructure directory: (for example)

cp ./artifacts/almost_erc20.json paradigm-ctf-infrastructure/images/cairo-challenge-base/compiled/almost_erc20.cairo

Running individual challanges

• Run the challenge script. The sever script should already be running in another terminal.

cd ./paradigm-ctf-infrastructure/images/cairo-challenge-base
python -m cairo_sandbox.proxy-chal.py

• Choose option 1 to create new environment

• Input any number (e.g. 1) as ticket

• Wait for the contracts to be deployed

• Copy the rpc endpoint, private key and contract to their respecable value in the solution script

Run the solution script

Run the solution script with

python ./scripts/cairo-auction.py
