This is a P2P service small nodes can use instead of looking for watchtower nodes. A great idea, highly undervaluated and unknown. Give it a try if you have a small node and share your feedback below. Note: be careful choosing a partner and roll 'em over time.

TL;DR; I'm introducing Watch Swaps, a service similar to the Liquidity Swaps, but instead of opening channels to each other, node operators will watch each other's nodes with their watchtower services to protect against malicious channel force closure attacks, and the resulting potential loss of funds.

LN+'s first feature, the Liquidity Swaps have been very successful in the last year or so. More than 12K liquidity swaps allowed Bitcoin lightning network node users to cooperate with each other and open 40K channels in a mutually beneficial and efficient way. Liquidity swaps weren't only beneficial to individual node operators but to the network as a whole as well, because together we managed to decentralize the network. LN became highly resilient to single large nodes dropping out or behaving in an unfriendly way. A good test for this was when recently the second largest node (zerofeerouting) in the network dropped out. There was virtually no interruption to payments thanks to the many other nodes and their channels that could be used to route around the missing node.
