| :------------------------ | :------------------------------------ | :--------------------------------------------------------- |
| **Transaction Not Found** | Wrong hash, wrong network, too recent | Verify hash, check network, wait for indexing              |
| **Failed Transaction**    | Out of gas, revert, invalid input     | Check gas limit, read revert reason, verify input          |
| **High Gas Fees**         | Network congestion, complex operation | Check gas price, simplify transaction, wait for lower fees |
| **Pending Too Long**      | Low gas price, network issues         | Increase gas price, check network status                   |
| **Wrong Token Amount**    | Decimal confusion, display issue      | Check token decimals, verify actual amount                 |
