Quick template to get started on Paradigm CTF challenges

Sample Hardhat Project

Installation

npm run install

Build challenge images

First download the challenge files from paradigm.xyz or from unofficial archive repo. Then add these two env variables to the challenge Dockerfile.

ENV ENV=dev
ENV ETH_RPC_URL=https://eth-mainnet.alchemyapi.io/v2/apikey

Then you can successfully build and run the image with approrpiate ports published.

docker build -t challenge .
docker run -p 31337:31337 -p 8545:8545 challenge
nc localhost 31337

You can use any value for team id.

Once you update your .env file with the information you got from above, try running pwn.ts file with hardhat.

npx hardhat run scripts/pwn.ts --network ctf

Solidity Compilation

npx hardhat compile

Using forge:

forge build

Using python

My preferred installation of python is to use pyenv. Then use mkvenv script to set your venv in your folder.

Run against CTF RPC

First, make sure your .env file is created and is filled with relevant info. Refer to .env.template.

npx hardhat run scripts/pwn.ts --network ctf

Run against local network

You could set up a docker but I found deploying the setup contracts myself to be easiest.

npx hardhat run scripts/pwn.ts --network hardhat

Have fun hacking!
