Why did the mining fees change for my swap?
Understanding why network fees fluctuate before and during your swap.
Mining (also known as network) fees are determined by blockchain activity and can change in real time.
The fee shown before you confirm your swap is the most accurate estimate available at that moment, but the final amount may vary slightly.
This happens because blockchain networks constantly adjust fees based on traffic, demand, and transaction volume. If the network becomes busier while your swap is processing, the required mining fee may increase to ensure your transaction is confirmed quickly.
These changes are normal and part of how decentralized networks maintain speed and reliability.
