Is it valid to create a 2/3 multisig address using a mix of HD keys and non- HD?
Reason I ask is because on bitcoin-cli when trying to sign, I'm getting an error about invalid private key when trying to sign a 2/3 tx with the HD child private key. It might be something else, but is this valid?
The exact error msg is this:
bitcoinrpc.authproxy.JSONRPCException: -5: Invalid private key
Thanks
