/**
 * fundrawtransaction "hexstring" ( options iswitness )
 *
 * If the transaction has no inputs, they will be automatically selected to meet its out value.
 * It will add at most one change output to the outputs.
 * No existing outputs will be modified unless "subtractFeeFromOutputs" is specified.
 * Note that inputs which were signed may need to be resigned after completion since in/outputs have been added.
 * The inputs added will not be signed, use signrawtransactionwithkey
 * or signrawtransactionwithwallet for that.
 * All existing inputs must either have their previous output transaction be in the wallet
 * or be in the UTXO set. Solving data must be provided for non-wallet inputs.
 * Note that all inputs selected must be of standard form and P2SH scripts must be
 * in the wallet using importaddress or addmultisigaddress (to calculate fees).
 * You can see whether this is the case by checking the "solvable" field in the listunspent output.
 * Only pay-to-pubkey, multisig, and P2SH versions thereof are currently supported for watch-only
 *
