NAME
     signpsbt  -- Command to sign a wallet's inputs on a provided bitcoin trans-
     action (PSBT).

SYNOPSIS
     signpsbt psbt [signonly]

DESCRIPTION
     signpsbt is a low-level RPC command  which  signs	a  PSBT  as  defined  by
     BIP-174.

     By default, all known inputs are signed, and others ignored: with signonly,
     only  those inputs are signed, and an error is returned if one of them can-
     not be signed.

     Note that the command will fail if there are no inputs to sign, or  if  the
     inputs to be signed were not previously reserved.

     *	psbt (string): The psbt to be signed.
     *	signonly (array of u32s, optional): Input numbers to sign.:
	*  (u32, optional)

RETURN VALUE
     On success, an object is returned, containing:

     *	signed_psbt (string): The fully signed PSBT.

ERRORS
     On failure, one of the following error codes may be returned:

     *	-32602:  Error	in  given parameters, or there aren't wallet's inputs to
	sign, or we couldn't sign all of signonly, or inputs are not reserved.

AUTHOR
     Vincenzo Palazzo vincenzo.palazzo@protonmail.com wrote the initial  version
     of  this man page, but many others did the hard work of actually implement-
     ing this rpc command.
