Layer 2 Execution Costs

Cost

Layer 2 execution costs represent the fees paid to process transactions on scaling solutions built on top of a base blockchain. These costs typically include a small fee for the Layer 2 operator or sequencer, along with a portion of the underlying Layer 1 gas cost required to finalize the transaction batch. The cost structure varies significantly between different Layer 2 technologies, such as rollups and sidechains, and depends on network congestion and the complexity of the smart contract interaction.
