SURFACE
Surface
What users see. Identity, motion, UI craft, copy.
A trading-grade UI that does not feel like a trading-grade UI. Order book in haptics, charting in 60fps, the deposit flow collapsed from 7 steps to 2. Dark-only by intent: the screen is a tool, not a poster.

What holds it up. Architecture, contracts, infra, latency.
Native Swift/Kotlin clients over a binary WebSocket multiplex. Order routing through a Go gateway with a Redis matching cache. Push-driven order updates, never polled. Biometric keys held in Secure Enclave / StrongBox.
