genevieveli1999/Flash-USDT-Tool ? reverse-engineered prompt

Build me a Python app with a simple terminal menu that lets me configure a wallet, pick a network, and send these short lived crypto transactions for USDT, BTC, or ETH. It should support Ethereum, TRON, BSC, and ideally Polygon and Arbitrum too, with options for ERC 20, TRC 20, and BEP 20, plus custom gas or energy settings, RPC selection, and a way to check transaction status after sending.

I want a clean interactive screen that shows wallet balance, lets me switch settings, and keeps the important config in a JSON file. Make it work on Windows, Linux, and macOS, with easy run scripts. If you need to, look up current docs online for the Python libraries that handle these chains. Also include a clear about screen and basic error handling so it feels polished and easy to use.
