00:00:00.820 --> 00:00:07.120
On Ethereum, gas measures the computational work a transaction requires.

00:00:07.120 --> 00:00:10.820
The fee depends on the gas used and its price.

00:00:11.140 --> 00:00:16.620
When demand for network capacity rises, the price of gas can rise.

00:00:16.620 --> 00:00:20.670
More complex actions can also use more gas.

00:00:20.967 --> 00:00:26.360
A transaction that is included but fails can still consume gas.

00:00:26.360 --> 00:00:30.287
Paying a fee does not guarantee your intended action succeeds.

00:00:30.920 --> 00:00:34.040
Review the network and fee estimate before signing.

00:00:34.040 --> 00:00:40.337
A lower-cost route only helps if the recipient supports it and you understand its risks.
