Building a DeFi Dashboard with Next.js: Track Positions Across Protocols

A DeFi dashboard aggregates a user positions across multiple protocols into a single view. Building one requires integrating with various smart contracts, normalizing data, and presenting it in a clear, actionable interface.

Data Aggregation Strategy

The challenge is that each protocol has different data structures and access patterns. The DeFi Dashboard template solves this with a unified position model that includes protocol, type (liquidity, lending, staking, yield), asset, amount, value in USD, APR, and risk level.

Protocol Integrations

Uniswap V3 positions require tracking NFT position IDs and collecting fee data. Aave positions need supply and borrow balance checks. Curve gauges require staked balance and reward rate queries. The template includes data stubs for eight major protocols that you can replace with live contract calls.

Portfolio Value Calculation

Sum up all position values and track changes over time. Display historical portfolio value using Recharts area chart with data from your backend or subgraph.

Risk Scoring

Implement a risk assessment system based on protocol TVL (higher is safer), audit recency and quality, liquidity depth, volatility of underlying assets, and concentration risk.

Real-Time Updates

Use WebSocket connections or polling to keep data fresh. Poll every 30 seconds with a refresh interval.

Charts and Visualization

The template uses Recharts for portfolio value over time (area chart), asset allocation (pie chart), APY comparison (bar chart), and gas costs (line chart).

The Bottom Line

The DeFi Dashboard template provides a complete analytics interface. By connecting live protocol data through the position model, you can offer users a comprehensive view of their DeFi portfolio across the entire ecosystem.
