Hey, I actually need to see how zkEVM works differently from Immutable X in terms of API requests... I saw they have a whole new set of endpoints, but I didn't go any further than that.

One thing you could consider is renting contracts. You could use membership tokens to pay for subscriptions or to offer discounts. The issue is of course bugs in the code that can cause leaks by hackers or for the tokens to be locked forever, for example. But I still think that could be a viable expansion of the business for you, enabled by Starkware's Cairo - that's what they're using, right?
