lightning-fundchannel_cancel -- Command for completing channel establishment


fundchannel_cancel id


fundchannel_cancel is a lower level RPC command. It allows channel opener to cancel a channel before funding broadcast with a connected peer.

id is the node id of the remote peer with which to cancel.

Note that the funding transaction MUST NOT be broadcast before fundchannel_cancel. Broadcasting transaction before fundchannel_cancel WILL lead to unrecoverable loss of funds.

If fundchannel_cancel is called after fundchannel_complete, the remote peer may disconnect when command succeeds. In this case, user need to connect to remote peer again before opening channel.


On success, an object is returned, containing:

  • cancelled (string): A message indicating it was cancelled by RPC

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.
  • 306: Unknown peer id.
  • 307: No channel currently being funded that can be cancelled.
  • 308: It is unsafe to cancel the channel: the funding transaction has been broadcast, or there are HTLCs already in the channel, or the peer was the initiator and not us.
