L2 Data Costs

Expense

L2 data costs represent the largest expense for rollup operators, directly influencing the fees charged to end-users. This cost is primarily determined by the gas price on the Layer 1 network and the amount of data posted per batch. High data costs on Layer 1 can make L2 solutions prohibitively expensive during periods of network congestion. The economic viability of Layer 2 solutions depends heavily on minimizing this expense.
