Submarine swaps, conceptualized by co-author Olaoluwa Osuntokun and Alex Bosworth, allow on-chain Bitcoin to be exchanged for Lightning Bitcoin and vice versa.
The user could initiate a submarine swap and send all available Lightning Bitcoin to the other party, who will then send them on-chain Bitcoin in exchange.
The on-chain Bitcoin could even be sent to a different wallet entirely.
The user has then successfully "sweeped" their Bitcoin off of the Lightning Network and is left with the minimum amount of satoshis in the channel required as a reserve and an open channel with inbound capacity.
In the future this could be a paid service offered by other Nodes on the Lightning Network which advertise exchange rates for the conversion.
