Chia advertises itself as being
A Smart Contract based chain supporting a Turing Complete language
On the 2nd i would expect to see a few features that might actually create more interest. Like a wrapping function (for wrapped Ethereum, Bitcoin, Stable coins), an atomic swapping/DEX mechanism (preferably an AMM) and corresponding yield farming capabilities . Most of the semantics have been worked out with Ethereum & its copies so mostly it would be about translating Solidity to Chialisp. After that something else challenging like Synthetix.
We already have NFT (a Chialisp singleton)
Surely farming is not all of it - I want it - I want it all !
