lightning-openchannel\_signed -- Command to conclude a channel open =================================================================== SYNOPSIS -------- **openchannel_signed** *channel_id* *signed_psbt* DESCRIPTION ----------- `openchannel_signed` is a low level RPC command which concludes a channel open with the specified peer. It uses the v2 openchannel protocol, which allows for interactive transaction construction. This command should be called after `openchannel_update` returns *commitments_secured* `true`. This command will broadcast the finalized funding transaction, if we receive valid signatures from the peer. *channel_id* is the id of the channel. *signed_psbt* is the PSBT returned from `openchannel_update` (where *commitments_secured* was true) with partial signatures or finalized witness stacks included for every input that we contributed to the PSBT. RETURN VALUE ------------ On success, returns the *channel_id* for this channel; hex *tx* of the published funding transaction; and *txid* of the funding transaction. 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. - 303: Funding transaction broadcast failed. - 309: PSBT missing required fields. - 311: Unknown channel id.
