Rollup transaction fee

A rollup transaction fee is the cost of processing a transaction on a layer-2 network that batches operations and publishes data or results on a base layer. It typically combines L2 execution with L1 data publication. The formula, additional charges and effective price depend on the network.

A rollup spreads batch-publication costs across transactions. Each operation also uses execution resources on L2. Some networks add their own components or margins.

EIP-4844 blobs have a fee market separate from Ethereum execution gas. Blob use and compression affect publication costs but do not establish one universal L2 fee.

Comparing fees requires measuring the same operation and considering both components. A simple transfer and a complex contract call have different requirements. An interface’s displayed price may be an estimate.
