LIGHTNING-SIGNPSBT(7)					 LIGHTNING-SIGNPSBT(7)

NAME
       lightning-signpsbt  --  Command to sign a wallet's inputs on a provided
       bitcoin transaction (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 cannot 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  re-
	  served.

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