I would like to ask the following. I've downloaded Bitcoin Core and just start using their "Console". Before I can createrawtransaction, I need to first set up a node in Bitcoin Core, right? If yes, I did follow the instruction in https://developer.bitcoin.org/reference/rpc/index.html.
However, when I want to apply a node for myself that is using --> addnode "188.8.131.52:8333" "onetry"
but end up is Null although I have requested for "getnodeaddresses" as per the screenshot:
Please advise as I need to "importprivkey" in order to perform the createrawtransaction.
Also, my apology I would like to ask this as well. Why when I send createrawtransaction in the Bitcoin Core Console, the error it states here that the error - Method not found (code -32601). Anyone can advise or provide guidance to me? I'm no expert in this. Thanks in advance.
