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 to
provide a PoDLE to the peer. 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).
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
