| 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 |
