lightning-openchannel\_init -- Command to initiate a channel to a peer ===================================================================== SYNOPSIS -------- **openchannel_init** *id* *amount* *initalpsbt* \[*commitment_feerate*\] \[*funding_feerate*\] \[*announce*\] \[*close_to*\] DESCRIPTION ----------- `openchannel_init` is a low level RPC command which initiates a channel open with a specified peer. It uses the openchannel protocol which allows for interactive transaction construction. *id* is the node id of the remote peer. *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. *commitment_feerate* is an optional field. Sets the feerate for commitment transactions: see **fundchannel**. *funding_feerate* is an optional field. Sets the feerate for the funding transaction. Defaults to 'opening' feerate. *announce* is an optional field. Whether or not to announce this channel. *close_to* is a Bitcoin address to which the channel funds should be sent on close. Only valid if both peers have negotiated `option_upfront_shutdown_script`. 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. 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. - 304: Still syncing with bitcoin network - 305: Peer is not connected. - 306: Unknown peer id. - 309: PSBT missing required fields - 310: v2 channel open protocol not supported by peer - 312: Channel in an invalid state SEE ALSO -------- lightning-openchannel\_update(7), lightning-openchannel\_signed(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.
