L2 Gas

Definition

L2 Gas refers to the computational fees required to execute transactions or operations on a Layer 2 scaling solution built atop a main blockchain, such as Ethereum. These fees compensate network validators or sequencers for processing and submitting aggregated transaction data to the Layer 1 chain. The primary purpose of Layer 2 solutions is to reduce the cost and increase the speed of transactions compared to direct Layer 1 execution. L2 gas costs are typically significantly lower due to off-chain processing and batching of transactions.
