Design a crypto portfolio web dashboard that gives users a single place to track everything they hold. It should connect to multiple wallets across Ethereum and Solana, pull balances and DeFi positions from major protocols like Aave and Compound, and present a unified, easy-to-scan portfolio view. The app must feel fast and dependable: run background jobs on a schedule (e.g., serverless functions on Google Cloud) to fetch, normalize, and store data in one database that the site reads from, rather than hitting chains directly on every page load. In the UI, include historical performance charts, clear realized/unrealized P&L, and a breakdown of allocation by asset and chain. Build the frontend with Next.js and provide a simple, trustworthy multi-wallet connect flow. Prioritize clarity, accuracy, and a data-rich experience over flashy visuals.
