I'm not familiar with hodl hodl so I will not comment.
But for Bisq, as I recall, Bisq decided to drop Lightning from their roadmap in Dec 2022, at least for Bisq2, because, as they put it,
We don't have enough resources to work on it. It doesn't make any sense to promise more than we can realistically deliver.
My question is how do they plan on implementing / integrating Lightning into their platform / app? Will they be acting as a trusted escrow for all Lightning trades like what Robosats is currently doing? But Robosats is a corporation while Bisq is a DAO; who does the escrow for Bisq? The mediators / arbitrators? What is the risk of rug pulls by trusted third parties in this case? Better yet, can Bisq implement P2P trading via Lightning without the need for trusted third parties?
