How network gas, route fees and quoted output affect the amount you receive.
Review the live route
The most useful comparison is the final amount you expect to receive relative to the amount you send. A route with a lower visible fee can still produce less output because of liquidity or exchange-rate differences.
Complete the transfer carefully
Network congestion can change gas costs quickly. Review the quote when you are ready to transact, and avoid treating a fee displayed several minutes earlier as guaranteed.
