Gas Fee
Protocol
Price paid for gas consumed by a transaction.
Gas fees pay validators for executing and storing transactions. On EVM chains, total fee equals gas used times the effective gas price, which is the base fee plus your tip. Wallets usually show a good estimate before you sign.
Frequently asked questions
How do I estimate my gas fee?
Multiply the estimated gas used by the effective gas price. Wallets provide estimates based on recent blocks.Why did I pay gas when a transaction failed?
Nodes still did work before the revert, so part of the gas is consumed. Review errors and try with a higher limit if needed.How can I lower gas fees?
Use off peak times, batch actions, or try an L2 where fees are lower. Set reasonable tips rather than maximums.
