Troubleshooting Guide

Issue	Possible Causes	What to Check
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
