Easy-Tracing

This tool is a proof of concept. It aims to represent Foundry traces in a dynamic way, with a set of features to facilitate navigation and analysis:

How it works

The tool is an SPA built with React + Material UI + Ethers.js.

npm i
npm run dev

To get started, you need to generate both ABIs and the traces to be analyzed:

forge build # by default, should create an out/ directory containing all ABIs
forge test -vvvv --json > test-traces.json # -vvvv maxes all info containing on traces

# alternatively, you can generate a cast trace
cast run  0x1f21a...d4 --json > tx-trace.json

Selecting the ABIs is selecting the root folder containing all ABIs to be used when parsing information. Together with the generated traces, it should automatically present a tree containing all info:

On ./test-data you can find some the generated traces and ABIs of uniswapv3-code to test the tool.
