ETHERNAUT-CTFS

I am using Foundry framework for solving the CTFs, I find it to be the most convenient one, you can just use solidity language to complete everything, no JS or PYTHON needed.

I solved 31 Ethernaut challenges in <4 days. I did not include the script file for most challenges, however if some more complex logic is needed for interacting with the contracts, it should be in the Attacks files.

For sure by the time you read this, there might be more CTFs added, I might add them in the future as well:)

to install libraries:

forge install OpenZeppelin/openzeppelin-contracts

I completed one challenge using Huff language. to install Huff (you need npm):

npm install -g huffc
forge install huff-language/huff-rs

for debugging, installation problems or anything else, ask your buddy ChatGPT. . . . . . .
