What Are Ethereum Gas Fees?
Gas fees pay for computation and transaction processing on Ethereum. Learn what influences fees, why they change, and why a failed transaction may still consume gas.
What gas pays for
Ethereum uses gas to measure the computational work required by a transaction. The fee depends on the amount of gas used and the network’s fee conditions.
Why fees change
Demand for block space changes over time, and more complex operations can require more gas. Wallet estimates are estimates; actual costs depend on the transaction and network conditions.
Avoid fee confusion
Network fees are distinct from protocol fees or other costs that may apply. Confirm the selected network and fee details before signing, and beware of anyone asking you to send extra funds to unlock a transaction.
