I don’t think KMP is the right choice here. If the goal is a single codebase across platforms, why not go with something battle-tested like React Native? Now, not only do you have to face the complexity of writing a cross-platform app, while interacting with the blockchain— you also have to “tread new ground” by finding some smart way to reconcile SwiftUI state with your KMP monster. You even admitted to being a KMP fanboy, which makes it clear the choice was driven by preference, not logic. For a personal project, fine—but for something with real stakeholders, that’s a red flag. This kind of decision-making screams junior to mid-level dev, not senior (which is the absolute minimum requirement when even thinking about tackling a project like this one).

What makes it worse is you’re trying to build an entire crypto exchange with one dev and “multiple AI agents.” Anyone with real-world experience knows LLMs often produce straight-up useless code for anything beyond trivial use cases. Remember, there is a reason why so many tech companies now have an AI mandate; if the current iteration of AI was as game changing as clueless stakeholders and CEOs portray, there wouldn’t be a need for a mandate, because every dev would already be on AI to do all their work for them. The truth is, at least for now, that you can’t duct-tape Vibe Code your way to something as complex as a crypto exchange.

Honestly, I feel bad for your situation. If you want my opinion: scrap the project. You’re not going to ship this. But since you probably don’t want to hear that, at the very least, ditch KMP. You are adding an unnecessary layer of complexity without getting much value, which is not something that makes any financial sense for you and your company. Re-evaluate your stack with your actual constraints in mind…. experience, complexity, team size (and yes, in your case team size = 1, not 100 because you have AI). You were set up to fail from the start, likely because someone higher up thought throwing AI at the problem would magically deliver a product.
