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.
