Distinguish a Gas Limit From a Gas Price

A gas limit measures the maximum execution work a transaction permits. A gas price measures the native-currency cost per unit of that work. Read the units before comparing two wallet fee displays.

Label each number before comparing it

Ethereum transaction documentation distinguishes gasLimit, maxFeePerGas and maxPriorityFeePerGas. The first concerns units; the other two concern price per unit under that fee model. A number such as 100,000 gas cannot be compared directly with 2 gwei. If a wallet displays only a currency total, open its fee details rather than assuming the total is the gas limit.

Work through a hypothetical execution fee

Suppose an illustrative transaction uses 60,000 gas at an effective price of 2 gwei per gas. Multiplication gives 120,000 gwei, or 0.00012 ETH, for that execution component. These invented numbers explain units; they are not current network estimates, recommended settings or a prediction for a swap. An original limit of 100,000 units would not make gasUsed equal 100,000.

Keep maximums and observed charges separate

Before inclusion, a wallet may display an estimate or maximum requirement. After inclusion, inspect the actual receipt and fee details. Do not treat a maximum price cap as the final effective price, or a limit as a statement about actual work. Increasing a limit is not the same as offering a higher price per unit, and neither change verifies the destination or requested contract operation.

Avoid incomplete Base comparisons

For Base, the execution component is only part of the fee calculation described in the network documentation. Compare complete fee breakdowns from the same chain and observation period. Keep network charges separate from a website’s interface fee and from the token amount. RunixCoin’s public Network Fee row is a quote estimate in dollars when available; it does not expose enough detail to reconstruct a signed transaction or establish the eventual network charge. No transaction is constructed by this guide.
