There’s a reason metamask is the most popular wallet in the world because it’s user friendly, multi chain and allows for self-custody. Obviously not as secure as a cold wallet buts it’s much bigger improvement that custodial lightning wallets.

I imagine if dc was implemented everyone would use a metamask style wallet that allows for various sidechains and main chain bitcoin with user friendly atomic swaps and peg ins and peg outs of sidechains.

That’s how I see it.
