Finalize the inputs of a PSBT. If the transaction is fully signed, it will produce a network serialized transaction which can be broadcast with sendrawtransaction. Otherwise a PSBT will be created which has the final_scriptSig and final_scriptWitness fields filled for inputs that are complete.
Implements the Finalizer and Extractor roles.

Argument #1 - psbt

Type: string, required
A base64 string of a PSBT

Argument #2 - extract

Type: boolean, optional, default=true
If true and the transaction is complete,
extract and return the complete transaction in normal network serialization instead of the PSBT.


{ (json object)
"psbt" : "str", (string) The base64-encoded partially signed transaction if not extracted
"hex" : "hex", (string) The hex-encoded network transaction if extracted
"complete" : true|false (boolean) If the transaction has a complete set of signatures
