Is the only thing we need to scale bitcoin Mercurylayer and Lightning? I think we might get very close.

Mercurylayer gives us non-custodial off-chain transfers within the statechain. Lightning gives us a way to do payments outside of the statechain via one or several "internal" LSPs.

This is basically Wallet of Satoshi but non-custodial. This is basically Fedimint without having to trust a federation.

Someone, please build this. NOW!
