Network fees and gas
Work out the full cost of a practice transfer and see why fees can change.
A fee is part of the cost
A network fee pays for processing a transaction. In a simple transfer of a network’s own currency, the sender covers the amount being sent plus the fee. On Ethereum, the network fee is paid in ether, also called ETH.
Gas measures the work
Ethereum measures the work a transaction takes in gas units. The fee depends on how many units the transaction uses and the price per unit. In our practice network, a transfer that uses 3 units at 2 credits per unit costs 6 credits in fees. Sending 10 credits would cost 16 credits in total.
Read the fee estimate
An action that does more work can use more gas, and the price per unit can change as demand changes. A wallet’s review screen can help you check the payment amount, the estimated fee, and the total before you approve anything.
