When I opened a channel, I funded a 2-of-2 multisig on Bitcoin, exchanged commitment transactions, and closed cooperatively; if offline, force-close after time lock.

Open: fund a 2-of-2 Bitcoin output; exchange off-chain commitment updates. Close: cooperative on-chain TX, or unilateral close via latest commitment with revocation.
