iunknow588/flashloan ? reverse-engineered prompt

Build me a Python project for experimenting with flash loan based crypto trading.

I want a simple app that can connect the pieces for a flash loan workflow, with separate smart contract folders for the bot side and the DEX side, plus a Python entry point that ties everything together. It should be easy to run locally, easy to test, and structured so I can later plug in real on chain logic, pricing checks, and trade execution.

Please keep it organized and working end to end as a starter project, with clear placeholders where the actual flash loan and swap logic would go. If anything needs current library or network setup details, look up the latest docs online if needed. Also make sure the project has a clean main script and sensible defaults so I can start from it right away.
