@carver Any thoughts on a better test for this? I'm having trouble figuring out why the eth_signTransaction call to geth is behaving differently from parity - any possible insight into that?
Also according to the spec the jsonrpc response should only include the raw signed transaction. However, both parity and geth also return the original tx params submitted in the request. What behavior do we want web3.eth.signTransaction to emulate? Just simple return the signed tx? or also include the original transaction params?

I don't think it is Web3.py's job to enforce spec compliance, that is going to be a separate thing that clients start testing for. For now, we should probably be quite forgiving with what data is returned (with respect to allowing these extra fields and formatting them in the expected way)
In the future, I could see it being reasonable for web3.py to even decode the transaction and populate these fields when the clients stop returning them.

This may be a dumb question, but why do we need both web3.eth.signTransaction and web3.eth.account.signTransaction?

Not dumb at all, it could very well be a dumb idea. My thinking was that web3.eth.account.signTransaction (aka Account.signTransaction from eth-account does pretty much the same thing as sending a eth_signTransaction JSONRPC request to a client, which is what web3.eth.signTransaction does. Since the eth-account implementation was well-done, it seemed to me a fair test comparison to make sure that web3.eth.signTransaction is performing as expected

Yup, pretty much the only difference is whether your private key is managed by your python app or your node.

Got it! That was the missing link 🔗. Thanks!

Nice catch! How do you feel about turning these into doctests so that we catch errors like this in the future? If it's too much for this PR, I'll add a new issue. I think it is a good idea to start moving that direction for all of our docs.

Agreed, I'm all for doctest and autodoc, but I think it's a somewhat hefty task and deserves it's own issue / pr(s).
What was wrong?
eth_signTransactionas defined in EIP 1474 is not implemented yet in web3.How was it fixed?
