lightning-fundchannel_start – Command for initiating channel establishment for a lightning channel

SYNOPSIS

fundchannel_start id amount [feerate announce close_to]

DESCRIPTION

fundchannel_start is a lower level RPC command. It allows a user to initiate channel establishment with a connected peer.

id is the node id of the remote peer.

amount is the satoshi value that the channel will be funded at. This value MUST be accurate, otherwise the negotiated commitment transactions will not encompass the correct channel value.

feerate is an optional field. Sets the feerate for subsequent commitment transactions: see fundchannel.

announce whether or not to announce this channel.

close_to is a Bitcoin address to which the channel funds should be sent to on close. Only valid if both peers have negotiated option_upfront_shutdown_script. Returns close_to set to closing script iff is negotiated.

Note that the funding transaction MUST NOT be broadcast until after channel establishment has been successfully completed by running fundchannel_complete, as the commitment transactions for this channel are not secured until the complete command succeeds. Broadcasting transaction before that can lead to unrecoverable loss of funds.

RETURN VALUE

On success, returns the funding_address and the scriptpubkey for the channel funding output. If a close_to address was provided, will close to this address iff the close_to address is returned in the response. Otherwise, the peer does not support option_upfront_shutdownscript.

On failure, returns an error.
