In this track: Gas and execution fees

Execution fees versus blob fees

Blob-carrying transactions have an additional data-resource dimension.

LET’S PICTURE IT

A delivery can charge separately for handling work and a special cargo compartment. One rate does not describe both resources.

This example supplies twenty-one thousand gas used. It is a simple teaching input, not a live estimate of a contract call.

Execution remains one component

Ordinary EVM execution uses its gas accounting and fee mechanism. A blob-carrying transaction also commits to additional blob data with separate blob gas and fee rules.

The data has a different access model

Blob data is not ordinary contract calldata that EVM execution can freely read byte by byte. Execution can access relevant commitments and supported mechanisms, while availability is handled through the protocol’s blob design.

Separate caps and markets

Blob pricing has its own mechanism and transaction constraints. Reusing an execution-gas formula as the complete cost of every blob transaction omits a component. Exact parameters can evolve through protocol upgrades.

Keep our calculator’s boundary clear

The local gas tool calculates supplied EIP-1559 execution inputs only. It explicitly excludes blob fees and layer 2 data fees, so its output should not be labeled a universal total transaction quote.

Does the local execution gas calculator include blob fees automatically?
