@Cake Wallet is this the spark protocol you consider using for lightning on cake? iirc @Seth For Privacy mentioned something about it on the latest citadel dispatch

If a user is currently on custodial wallet of Satoshi, privacy sucks as is. The move to the self custody mode in the same app doesn't improve it, but will give more control of the funds. I'm not making an argument for people to ditch better options in favor of this. I'm simply showing how it works and the flow to switch if you're already using the app. I've got plenty of videos on how to be self sovereign with your own setup, or make trade-offs with private options like Cashu.
