I am moving this gist to a github repo so more people can contribute to it. Also, it makes it easier for me to version control.

Please go to - https://github.com/praveenpuglia/shadow-dom-in-depth for latest version of this document. Also, if you find the document useful, please shower your love, go ⭐️ it. :)

this script collect can be used to collect all events, transactions, call traces, and state diffs associated with Uniswap swaps
# for uniswap v3 swaps, this script will collect all associated...
# - events
# - transactions
# - call traces
# - state diffs
# you can modify the block range and add other args to fit your use case
# note that this script uses cryo command chaining, which allows the output of one command to be used as the input to another
