Read Both Components of a Base Network Fee

A small Base gas-price figure does not by itself describe the total transaction fee. When comparing estimates, identify the cost components included in each figure and whether it describes a limit, estimate or confirmed charge.

Name the components before comparing totals

Base’s current fee documentation describes an L2 execution fee and an L1 security fee associated with publishing transaction data. Those components respond to different network conditions. A calculation using only execution gas and its price may therefore omit part of the total. Refer to Base’s current specification for the applicable calculation rather than assuming an old tutorial or a simple Ethereum multiplication covers every field.

Use a reconciliation worksheet

For a hypothetical transaction review, make rows for execution estimate, publication-related estimate, total native-currency estimate and any separately disclosed application charge. Mark a component “unknown” when it is absent instead of filling it with zero. Keep the transaction’s transferred native value outside the network-fee total. This worksheet is an interpretation aid; the numbers must come from a source that actually explains what its estimate includes.

Check timing and display conversion

Two observations at different times can disagree because the request, state, network pricing or displayed currency conversion changed. Compare the same action on the same chain and retain the original ETH amounts. A dollar approximation cannot establish the exact ETH that a wallet will need. Also avoid using a minimum gas-price parameter from documentation as a promised total transaction cost: transaction size and other fee components still matter.

Apply the distinction to RunixCoin

The public form’s estimated USDC output and its interface-fee disclosure concern the quoted token exchange. Network fees are a separate category paid in the relevant gas currency in a normal transaction flow. RunixCoin currently cannot execute that public swap, so an estimate is not evidence that any component was charged. Do not add a fee display to an output deduction without first checking units and scope. This page changes no configured rate and recommends no fee override or signing action.
