lightning-openchannel\_bump -- Command to initiate a channel RBF ===================================================================== SYNOPSIS -------- **openchannel\_bump** *channel\_id* *amount* *initalpsbt* [*funding\_feerate*] 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. Warning: bumping a leased channel will lose the lease. RETURN VALUE ------------ [comment]: # (GENERATE-FROM-SCHEMA-START) On success, an object is returned, containing: - **channel\_id** (hex): the channel id of the channel (always 64 characters) - **channel\_type** (object): channel\_type as negotiated with peer *(added v24.02)*: - **bits** (array of u32s): Each bit set in this channel\_type *(added v24.02)*: - Bit number - **names** (array of strings): Feature name for each bit set in this channel\_type *(added v24.02)*: - Name of feature bit (one of "static\_remotekey/even", "anchor\_outputs/even", "anchors\_zero\_fee\_htlc\_tx/even", "scid\_alias/even", "zeroconf/even") - **psbt** (string): the (incomplete) PSBT of the RBF transaction - **commitments\_secured** (boolean): whether the *psbt* is complete (always *false*) - **funding\_serial** (u64): the serial\_id of the funding output in the *psbt* - **requires\_confirmed\_inputs** (boolean, optional): Does peer require confirmed inputs in psbt? [comment]: # (GENERATE-FROM-SCHEMA-END) 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. ERRORS ------ 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 SEE ALSO -------- lightning-openchannel\_init(7), lightning-openchannel\_update(7), lightning-openchannel\_signed(7), lightning-openchannel\_abort(7), lightning-fundchannel\_start(7), lightning-fundchannel\_complete(7), lightning-fundchannel(7), lightning-fundpsbt(7), lightning-utxopsbt(7), lightning-multifundchannel(7) AUTHOR ------ @niftynei <> is mainly responsible.
