@naiba can we please add a unit test for this, explaining why it was wrong before? realize this is a bit pedantic- appreciate the patience

Gas fees are dynamic, and if writing unit tests we can only assume gas fees on the polygon chain will never go below and above a certain value, which is kind of useless.

The following two links are descriptions of gas fee units. I believe you have already understood the unit conversion from gwei to wei.

Note this text: {'safelow', 'standard', 'fast', 'estimatedBaseFee'} are gas prices in GWei

ok this seems fine - just realized that polygon returns gwei and not wei - cc @recmo
