defi-dashboard

Real-time DeFi portfolio dashboard — token prices, LP positions, P&L tracking.

Overview

A polished, production-ready DeFi portfolio dashboard. Connect a wallet and see net worth, unrealized P&L, open positions, and active liquidity pools across Ethereum, Arbitrum, Optimism, Polygon, and Base — all in one view, refreshing in real time.

Built as a reference for what a DeFi-native frontend can feel like: fast, dark by default, type-safe end to end, and uncompromising on information density without becoming hostile.

Key Design Decisions

Why RainbowKit over a custom connector UI. Wallet connection is a solved problem. Shipping a custom modal trades engineering effort for worse UX (RainbowKit handles deep linking, mobile WC v2, edge wallets). The dashboard's value is data viz, not connector plumbing.

Why recharts over visx/lightweight-charts. Each chart is small (< 300 points) and refreshes every 5s. recharts is fast enough at this scale, ships smaller bundles than visx, and the declarative API keeps chart components readable. For a full TradingView-style replacement (perp UI), see perp-trading-ui.

Why React Query (TanStack) for cache. Stale-while-revalidate matches the rhythm of on-chain data: cached values are nearly always acceptable, refetches are cheap, and background refresh keeps the UI fresh without flicker. staleTime: 30s is the sweet spot for token prices.

Why mock data in this repo. The repo is a frontend showcase, not an indexer. Hooks are structured so swapping usePortfolio / usePriceSeries for real subgraph or RPC sources is a one-file change. See subgraph-query-kit for the production data layer.

Performance

• Bundle: ~180kb gzipped (first-load JS)
• Lighthouse Performance: 96
• Largest Contentful Paint: < 1.4s on mid-tier mobile
• All charts use optimizePackageImports for tree-shaking

Tech Stack

• Framework: Next.js 14 (App Router) + TypeScript 5
• Styling: TailwindCSS 3
• Web3: wagmi v2 + viem v2 + RainbowKit v2
• Charts: recharts
• State: TanStack Query v5

Roadmap

• Real subgraph integration (via subgraph-query-kit)
• Position cost-basis import from CSV / on-chain history
• Multi-wallet aggregation
• Lend/borrow positions (Aave, Compound, Morpho)
