gemini-python VS python-bitcoin-utils

It requires the gemini-python module, which I found did not yet implement the wrap_order endpoint, so I fiddled with the code and called the API directly:

I'm using a Python API (https://github.com/mtusman/gemini-python) to access the Gemini Sandbox. I would like to place some dummy limit buy orders. I notice that when I submit a buy order that is below the market price (ETHUSD was $4430 when I ran this), the result tells me the order was cancelled ...

Yeah exactly I used https://github.com/mtusman/gemini-python. I don't use the library directly though, I copy/pasted the pieces I needed out of it, audited them to make sure it wasn't shady, and made my own local Python script, mostly because of paranoia of trusting someone else's code blindly. This is honestly uneccessary but it makes me feel better.

I have the following code that successfully created a bitcoin transaction with https://github.com/karask/python-bitcoin-utils:

Thanks for the response. While I understand the process that happens, I just cant seem to figure out how to generate a P2SH address from a public key. I am looking at this library https://github.com/karask/python-bitcoin-utils which appears to be more in depth, but still cant understand it.
