It's the same space but most "solutions" in the space (like Lit Protocol) are actually custodial solutions parading as non-custodial. If you look closer at Lit Protocol, you will see that their nodes are unknown and unamed providers. Reading between the lines, it's just Lit hosting everything.
I actually just has a call with David from Lit Protocol. He patiently explained some of the nuanced pieces of Lit Protocol. A lot of this information is out there but they are moving so fast that it's hard to find. They are going to update their docs to make it more apparent but they have named their providers and appear to have a robust distributed network for key storage. Sorry for the hasty comment! It looks like Lit Protocol is one of the few non-custodial and resilient systems out there.
