Solve locally (WIP)

Clone GitHub repo + install deps

git clone https://github.com/waterfall-mkt/curta-puzzles.git && cd curta-puzzles && forge install

Set RPC_URL_MAINNET in .env

.env

RPC_URL_MAINNET=""

Write solution + run script

forge script <PATH_TO_PUZZLE> -f mainnet -vvv

This is still WIP.
