    Assuming wallet RPCs and node RPCs will go into different processes, signrawtransactionwithkey doesn’t need to access Coins via interfaces::Chain, it may use directly utility in node/coins.cpp

    Obviously will need rebase after #15638

    You should just be able to forward declare the Coin object and leave this include in the .cpp file if you change the coins argument into a reference.

    (thanks to @ryanofsky for answering my question about this)

    ariard commented at 12:41 pm on April 12, 2019:
    Just forward declaration seems to do the job without gcc complaints
    jnewbery commented at 9:05 pm on April 12, 2019:
    Thanks. You should pass by reference anyway, otherwise this will make a copy of the entire map.

    Like @jnewbery said, could be const std::map<COutPoint, Coin>& coins).
    ariard commented at 1:18 pm on April 13, 2019:
    Updated to pass-by-reference but I think can’t be const due to coins[out] = std::move(newcoin) L198 ?
    jnewbery commented at 4:50 pm on April 13, 2019:
    I think you’re right that it can’t be const
    promag commented at 10:22 am on April 14, 2019:
    Then I think it should not pass by reference or you could comment that coins is modified after the call.
    ariard commented at 12:40 pm on April 16, 2019:
    @promag followed your suggestion and also took the opportunity to add comments for all SignTransaction params

    I mean you can remove the interfaces namespace.

    promag is saying you can remove the forward declaration of the interfaces::Chain class.
