NAME

sendpsbt -- Command to finalize, extract and send a partially signed bitcoin transaction (PSBT).

SYNOPSIS

sendpsbt psbt [reserve]

DESCRIPTION

The sendpsbt is a low-level RPC command which sends a fully-signed PSBT. If the PSBT is the same one promised by a channel (via fundchannel_complete) it will also be associated with that channel and re-transmitted if necessary on restart.

• psbt (string): The fully signed psbt to be sent.

• reserve (u32, optional): Number of blocks to increase reservation of any of our inputs by. The default is 72.

RETURN VALUE

On success, an object is returned, containing:

• tx (hex): The raw transaction which was sent.

• txid (txid): The txid of the tx.

ERRORS

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

•

-32602: Error in given parameters or some error happened during the command process.

AUTHOR
