Rollup Fee Mechanisms

Mechanism

Rollup fee mechanisms define the system used by Layer 2 rollups to calculate and charge transaction fees to users. These mechanisms are designed to significantly reduce costs compared to Layer 1 by batching multiple transactions together and amortizing the high cost of L1 data availability across all transactions in the batch. The fee structure typically includes a base fee for L2 execution and a variable component for L1 data posting, which fluctuates based on network congestion.
