Built our entire crypto onboarding flow as code before design. The withdrawal screen broke 3 times.

We just finished wireframing our entire onboarding flow as interactive React components — 19 screens covering signup to first deposit.

The biggest lesson: building wireframes as code instead of static mockups catches logic mismatches early. Our withdrawal screen alone went through 3 iterations because the fee structure and destination toggle worked differently in code than it did on paper.

For context, we are building an AI-powered crypto trading platform focused on simplifying the experience for people who own crypto but find existing trading tools too complex. Non-custodial, performance-aligned fees.

The DeFi onboarding problem (CEX withdrawal > wallet setup > bridging > vault deposit) is still the biggest friction point in this space. We are collapsing that into a single step.

Has anyone else tried the code-first wireframe approach for crypto UX? Curious if others hit similar logic-vs-design gaps.
