Will it still use HBD for transactions

Yes!

WASM is cool, but I saw a lot of WASM chains fail in the past because not much love of devs. It is smart and efficient, but also means a lot of code must be rewritten to WASM ( at least what I saw).

This is definitely consideration and we will take a look into options to further decrease the developer onboarding cost. However, it is worth noting our primary customers are end users and less so dapps for the short term future. As the project grows it'll become easier to bring in developers.

Some dapps are out to test? Like a uniswap/ dex style of thing?
