Web3 Wallet Interface Concept

Design a premium mobile web3 wallet app mockup for a fictional wallet called NOVA VAULT on a 1179x2556 phone screen, centered on a dark graphite background with faint aurora gradients. Use a refined palette of black, electric cyan, emerald, violet-blue, and soft white. The app should feel modern but credible, with crisp typography, glassmorphism only where useful, and strong financial UI clarity. Include in-image text: "NOVA VAULT", "Portfolio $48,920.14", "24h +3.82%", "Send", "Receive", "Swap", and "History". Show token cards labeled "SOLAR 18.42", "LATTICE 244.7", and "USDX 12,840.00" with small sparkline charts. Add a security section reading "Shield Level 96" and a network selector labeled "Mainnet". Include a recent activity list with "Swap SOLAR to USDX", "Received 240 LATTICE", and "Gas 0.0021". Prioritize crisp labels, exact numbers, clean hierarchy, believable wallet UX, and polished gpt-image-2-friendly UI detail.
