Base Gas Fees, Explained
Base executes activity away from Ethereum mainnet and settles data back to Ethereum in batches. That changes the cost structure, but it does not make transaction fees fixed.
Key idea
Base fees are usually lower, not free or constant. Review the estimate before every signed action.

Base Tools →Why costs are usually lower
Layer 2 networks can spread settlement and data costs across many transactions instead of making each action pay the full cost of mainnet execution.
What still changes the fee
Demand on Base, transaction complexity and the cost of publishing data to Ethereum can all influence the final amount.
Estimate in the asset you pay
A useful wallet confirmation shows the network fee before approval. Compare that estimate with the action you are taking rather than assuming every Base transaction is negligible.
