I put in a pull request with the fix if you want to see what is different. You were on the right path, wrong key. Also, it's the hive-nectar library you are wanting to use in place of beem, nectarengine does a lot of what you have coded automatically if you want to look into it at a later date. But for the transaction builder, signer, etc, it's hive-nectar pip install hive-nectar and basically anything that used to say beem replace with nectar.
I'm not exactly familiar with how GitHub works...
So we're removing the posting key...
and each bit of inputs would be "from hive.nectar input ______"
it's just from nectar import ____ the package that you install with pip is called hive-nectar because just nectar was taken by someone else with pip. You can ignore the github pull request. Just compare mine, to yours and you will see the difference, but it's all between line 65 and 80 in this file: https://github.com/TheCrazyGM/peakecoin_bnb_bot/blob/main/place_order.py
Its running right now. I'm about to write up a post about it and post the updates and what have you. It's running right now. So after a day or so I'll see what happens. I'm also looking to build a swap for a token that isn't on the Hive Exchange, like an Atomic swap for PeakeCoin. If you can point me in any direction.
