|
||
|
|
=====================================================================
|

|
|
|
||
|
|
SYNOPSIS
|
||
|
|
--------
|
||
|
|
|
||
|
|
**openchannel_bump** *channel_id* *amount* *initalpsbt*
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
`openchannel_bump` is a RPC command which initiates a channel
|
||
|
|
RBF (Replace-By-Fee) for the specified channel. It uses the openchannel protocol
|
||
|
|
which allows for interactive transaction construction.
|
||
|
|
|
||
|
|
*id* is the id of the channel to RBF.
|
||
|
|
|
||
|
|
*amount* is the satoshi value that we will contribute to the channel.
|
||
|
|
This value will be _added_ to the provided PSBT in the output which is
|
||
|
|
encumbered by the 2-of-2 script for this channel.
|
||
|
|
|
||
|
|
*initialpsbt* is the funded, incomplete PSBT that specifies the UTXOs and
|
||
|
|
change output for our channel contribution. It can be updated,
|
||
|
|
see `openchannel_update`; *initialpsbt* must have at least one input.
|
||
|
|
Must have the Non-Witness UTXO (PSBT\_IN\_NON\_WITNESS\_UTXO) set for
|
||
|
|
every input. An error (code 309) will be returned if this requirement
|
||
|
|
is not met.
|
||
|
|
|
||
|
|
RETURN VALUE
|
||
|
|
------------
|
||
|
|
|
||
|
|
On success, returns the *channel_id* for this channel; an updated
|
||
|
|
incomplete *initialpsbt* for this funding transaction; and the flag
|
||
|
|
*commitments_secured*, which indiciates the completeness of the
|
||
|
|
passed back *psbt*. (Will always be false). Also returns the
|
||
|
|
*funding_serial*, indicating the serial\_id of the funding output
|
||
|
|
in the *psbt*.
|
||
|
|
|
||
|
|
If the peer does not support `option_dual_fund`, this command
|
||
|
|
will return an error.
|
||
|
|
|
||
|
|
If the channel is not in a state that is eligible for RBF, this command
|
||
|
|
will return an error.
|
||
|
|
|
||
|
|
On error the returned object will contain `code` and `message` properties,
|
||
|
|
with `code` being one of the following:
|
||
|
|
|
||
|
|
- -32602: If the given parameters are wrong.
|
||
|
|
- -1: Catchall nonspecific error.
|
||
|
|
- 300: The amount exceeded the maximum configured funding amount.
|
||
|
|
- 301: The provided PSBT cannot afford the funding amount.
|
||
|
|
- 305: Peer is not connected.
|
||
|
|
- 309: PSBT missing required fields
|
||
|
|
- 311: Unknown channel id.
|
||
|
|
- 312: Channel in an invalid state
