Gas Optimization on L2s

This lesson is for enrolled learners

Gas optimization on an L2 requires a different mental model than optimizing for L1 mainnet, because the cost structure is different. On L1, minimizing opcode count (storage reads/writes, expensive operations like SLOAD) is usually the dominant lever, since execution gas is the whole story. On most rollups — even after EIP-4844's blob-cost reduction — the L1 data-posting fee remains a……
