# 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](ai-crypto-trading-agent.md#step-1-install-universal-crypto-mcp) 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
```
