-  The OP Stack maintains a distinct gas limit compared to the Ethereum mainnet.\
-  While both chains use the same underlying transaction formats, Optimism's gas limits are tailored for optimal Layer 2 performance and scalability.\
-  As a result, transactions on Optimism may behave differently from the mainnet regarding gas usage and fee estimation.\
