    What is the main security benefit of using immutable variables?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    immutable variables are stored directly in bytecode, not in storage, reducing runtime gas and preventing accidental overwrites. It is a common optimization technique in gas-efficient contract design.

    Which gas pattern reduces redundant SSTOREs?

    Tip: Click "Play" to reveal options and start playing.

    #A
    #B
    #C
    #D
    Explanation:
    State Caching helps optimize gas by storing frequently used state variables in memory instead of repeatedly writing them to the blockchain. Since every SSTORE (state write) costs significant gas, caching reduces redundant storage operations, making smart contracts more efficient and cost-effective.
