Cross-Chain Portfolio Tracker

Tutorial: Build an AI-powered portfolio tracker that monitors your assets across 15+ blockchains simultaneously.

The Problem

Managing crypto across multiple chains is painful: - Checking 10 different block explorers - Manually calculating total portfolio value - Missing price movements on lesser-used chains - No unified view of DeFi positions

The Solution

With Universal Crypto MCP, you can ask Claude:

"Show me all my assets across every chain"

And get a complete portfolio breakdown in seconds.

Setup

Follow the basic setup guide first.

Usage Examples

1. Full Portfolio Scan

Scan my wallet across all supported chains and show me:
1. Token balances on each chain
2. Total USD value per chain
3. Overall portfolio value

Wallet: 0x742d35Cc6634C0532925a3b844Bc9e7595f12345

Claude will: - Query balances on Ethereum, Arbitrum, Base, Polygon, Optimism, etc. - Fetch current prices for each token - Calculate and display totals

2. Track Specific Tokens

Where do I hold USDC across all my chains? Show amounts and USD values.

3. Monitor DeFi Positions

Show me all my active DeFi positions:
- Aave deposits and borrows
- Uniswap LP positions
- Staking positions

Include health factors and APYs.

4. Daily Portfolio Summary

Give me a daily portfolio summary:
- Total value vs yesterday
- Biggest gainers/losers
- Any positions needing attention (low health factor, expiring farms)

Example Output
