fundrawtransaction "hexstring" ( options )
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.
Note that all existing inputs must have their previous output transaction be in the wallet.
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
Arguments:
1. hexstring (string, required) The hex string of the raw transaction
2. options (json object, optional) Options object that can be used to pass named arguments, listed below. For backward compatibility: passing in a true instead of an object will result in {"includeWatching":true}
Named Arguments:
add_inputs (boolean, optional, default=true) For a transaction with existing inputs, automatically include more if they are not enough.
include_unsafe (boolean, optional, default=false) Include inputs that are not safe to spend (unconfirmed transactions from outside keys).
Warning: the resulting transaction may become invalid if one of the unsafe inputs disappears.
If that happens, you will need to fund the transaction with different inputs and republish it.
changeAddress (string, optional, default=pool address) The bitcoin address to receive the change
changePosition (numeric, optional, default=random) The index of the change output
includeWatching (boolean, optional, default=true for watch-only wallets, otherwise false) Also select inputs which are watch only.
Only solvable inputs can be used. Watch-only destinations are solvable if the public key and/or output script was imported,
e.g. with 'importpubkey' or 'importmulti' with the 'pubkeys' or 'desc' field.
lockUnspents (boolean, optional, default=false) Lock selected unspent outputs
feeRate (numeric or string, optional, default=not set: makes wallet determine the fee) Set a specific fee rate in XEC/kB
subtractFeeFromOutputs (json array, optional, default=[]) The integers.
The fee will be equally deducted from the amount of each specified output.
Those recipients will receive less bitcoins than you enter in their corresponding amount field.
If no outputs are specified here, the sender pays the fee.
[
vout_index, (numeric) The zero-based output index, before a change output is added.

]
Result:
{ (json object)
"hex" : "hex", (string) The resulting raw transaction (hex-encoded string)
"fee" : n, (numeric) Fee in XEC the resulting transaction pays
"changepos" : n (numeric) The position of the added change output, or -1
}
Examples:
Create a transaction with no inputs
> bitcoin-cli createrawtransaction "[]" "{\"myaddress\":10000}"
Add sufficient unsigned inputs to meet the output value
> bitcoin-cli fundrawtransaction "rawtransactionhex"
Sign the transaction
> bitcoin-cli signrawtransactionwithwallet "fundedtransactionhex"
Send the transaction
> bitcoin-cli sendrawtransaction "signedtransactionhex"
