I just pushed an update to the repo that changes the getPublicKey test file to using py3.

I'm improving the tests right now since there are a lot of people wanting to get active now. Should have some more commits today

To test the signing, signTransaction, you currently need to use py2

Thanks for the reply, I was wondering if it was a typo. I guess it is time to dust off my Ledger Nano S and put it to use.
