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


fundchannel_start id satoshi [feerate announce]


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.

satoshi 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.

announce whether or not to announce this channel.

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.


On success, returns the funding_address and the scriptpubkey for the channel funding output.

On failure, returns an error.
