Closing a channel:

If you’ve decided that the channel you’ve opened is insufficient (too small) or problematic (bad routing), you can close the channel one of 2 ways.

First, get the channel details:

lncli listchannels

• Locate the channel_point.

...

Option 1 (best; cooperative):

Close an active channel with a closing transaction. Simply post a close request using:

lncli closechannel 926fb8fc1aa69432bcaa7e4aa7b0cf9cde6f24378870b8a22b92eb036175ac1e 1

• NOTE: the 2 parameters are separated by a colon in listchannels. Replace the colon with a space when passing the parameters to closechannel.

• Your funds should be available within a few mining confirmations.

Option 2 (forced; unilateral );

Closes any channel, but may take a few weeks to recover your funding. In some situations you have no choice, such as when the channel goes inactive.

lncli --force closechannel 926fb8fc1aa69432bcaa7e4aa7b0cf9cde6f24378870b8a22b92eb036175ac1e

• The funds may take a few weeks to return to your wallet. Use only as a last resort!
