Figma UX for Gold E-commerce

I’m building an e-commerce experience focused on digital gold—users can buy, sell and invest in gold directly from the app. I’ve mapped the core flows conceptually, but I now need polished, platform-specific screens created in Figma for Web, iOS and Android.

Here’s what I’m after:
• A complete set of high-fidelity screens that covers onboarding, browsing current gold rates, initiating a buy or sell, reviewing a portfolio, and confirming transactions.
• Consistent UX patterns across Web, iOS and Android while respecting each platform’s native conventions.
• A shared component library and styles so future iterations remain cohesive.
• Click-through prototypes in Figma so stakeholders can experience the end-to-end journey.

I’ll supply the brand palette, a rough sitemap and any reference material you need. Hand-off should include the organised Figma file, exported assets and a brief note explaining design logic or interaction nuances. If this scope sounds clear, let’s talk timelines and get started.
