Introduces a protocol-level maximum gas limit of 16,777,216 (2^24) per transaction. Transactions above this cap are rejected during validation, and Base adopts the same cap as L1 to maximize Ethereum equivalence. Deposit transactions will be exempt from the transaction gas limit cap. They are already limited to 20,000,000 gas as that is the most gas that can be included in an L1 block.

App developers with very large gas transactions may need to make adjustments to their contracts to ensure they don't exceed the gas limit. Wallet developers should enforce the cap at transaction creation.
