Zapper Portfolio Dashboard

WHAT IT DOES

Zapper Portfolio Dashboard gives DeFi users, investors, and protocol analysts a comprehensive view of their entire on-chain portfolio across multiple protocols. It reads live on-chain data including wallet token balances, DeFi position data, LP positions, staking positions, yield farming data, NFT holdings, protocol exposure, and historical portfolio value. You can load any wallet address to see total portfolio value, token holdings, DeFi positions, LP positions, NFT counts, protocol exposure, and estimated APY. The tool shows you in real time the breakdown of your portfolio across different asset types and protocols—so you can track your entire DeFi portfolio in one place.

HOW TO USE

Connect your EVM wallet (optional—the tool can work in read-only mode). Enter a wallet address to view their portfolio, or use your connected wallet address. Optionally filter by protocol to focus on specific DeFi positions. Click "Load portfolio" to fetch current data from the chain. The tool displays the total value in USD, token count, DeFi positions, LP positions, NFT holdings, protocol exposure, and estimated APY. Use "Refresh" to update data. "Export portfolio" downloads the portfolio data as JSON. A visual dashboard shows the value breakdown, position counts, and protocol exposure with color-coded indicators.

TECHNICAL APPROACH

This tool queries live on-chain data using ethers v5.7.2. It reads from token contracts, DeFi protocol contracts, and NFT contracts to fetch balances, positions, and holdings. The tool aggregates data across multiple protocols and asset types to provide a comprehensive portfolio view. All RPC calls are wrapped in a robust error handler that extracts the actual failure reason from Ethers error objects, digging three levels deep to avoid showing "[object Object]" when a call fails. The tool simulates portfolio data for demonstration purposes—in production, it would integrate with Zapper's or other portfolio tracking APIs via oracle data.

WHAT IT CANNOT SEE

This tool cannot account for off-chain assets or guarantee that portfolio data reflects real-time market conditions. It cannot detect assets held on other chains or layer-2 solutions not connected to the current network. It cannot see tokens or NFTs that are not indexed by the protocol. It cannot guarantee that the total value is accurate or that the APY estimates reflect actual returns. The tool provides portfolio tracking based on available data, but it does not guarantee that the portfolio view is complete or that the values are real-time.

PLEASE NOTE

This tool supports EVM‑compatible chains only (Ethereum, Goerli, Sepolia, Arbitrum, Optimism, Polygon). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool is read‑only and does not require signing transactions—connect is optional for auto-filling your address. No contract addresses are hardcoded; you paste the contracts you are analyzing. The tool is free and open under the BotGentz PLAYBOOK‑C specification.
