I came across Atomic Finance yesterday.
Non custodial options on BTC, so far they can only be bought (they are selling a "passive strategy" - specifically they are selling collective covered calls where they have 70 BTC locked). Pretty nice, although they are on-chain, if they did it like @get10101 it would be even more cool, because there would be no onchain fees.
Unfortunately those options are only very near-money and not too long expirations.
What I like is how they explain it all, it's almost like an embedded educational platform, although there's no better education than being nicely rekt by your own mistakes:)
