 ## Crafting Your Query
 
-1. **Identify Your Columns**: Once you've zeroed in on the right table, pinpoint the `tx_fee_usd` column to track USD gas expenditures. To specify the wallet you're examining, use the `tx_sender` field. For demonstration purposes, we'll be using Vitalik's wallet (0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045).
