+# Cross-Protocol Analytics: Query data across multiple protocols
+#
+# This is a conceptual example showing how you might query multiple subgraphs
+# to analyze cross-protocol strategies and positions.
+#
+# In production, you would:
+# 1. Query multiple subgraphs (Uniswap, Aave, etc.)
+# 2. Combine the data
+# 3. Calculate metrics like:
+#    - Total TVL across protocols
+#    - Cross-protocol arbitrage opportunities
+#    - User positions across protocols
+#    - Protocol interaction patterns
+
+# Example: Query user's Aave position and Uniswap LP positions
+# (This would require querying two separate subgraphs and combining results)
+
+# Query 1: Get user's Aave positions
+# (Use Aave subgraph - see aave-positions.graphql)
+
+# Query 2: Get user's Uniswap v3 positions
+query GetUserUniswapPositions($userAddress: String!) {
+  positions(
+    where: { owner: $userAddress }
+    first: 100
+  ) {
+    id
+    owner
+    pool {
+      id
+      token0 {
+        symbol
+      }
+      token1 {
+        symbol
+      }
+      feeTier
+    }
+    liquidity
+    depositedToken0
+    depositedToken1
+    withdrawnToken0
+    withdrawnToken1
+    collectedFeesToken0
+    collectedFeesToken1
+    transaction {
+      timestamp
+    }
+  }
+}
+
+# Query 3: Get protocol volumes (for analytics)
+query GetProtocolVolumes {
+  # Uniswap volume (example)
+  uniswapDayDatas(
+    orderBy: date
+    orderDirection: desc
+    first: 30
+  ) {
+    date
+    dailyVolumeUSD
+    totalVolumeUSD
+    tvlUSD
+  }
+  
+  # Aave volume (example - would need Aave subgraph)
+  # aaveDayDatas {
+  #   date
+  #   dailyDepositsUSD
+  #   dailyBorrowsUSD
+  #   totalValueLockedUSD
+  # }
+}

+# Query 4: Get token prices across protocols

+  # Uniswap price

+    id
+    symbol

+  #   id
+  #   symbol
+  #   price {
+  #     priceInUsd
+  #   }
+  # }
+}
+
+# Query 5: Get arbitrage opportunities
+# (Conceptual - would require real-time price comparison)
+query GetArbitrageOpportunities {
+  # Get pools with significant price differences
+  # This is a simplified example - real arbitrage detection is more complex
+  pools(
+    where: {
+      # Filter by high volume and liquidity
