    What breaks if virtual is omitted in multiple inheritance?

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

    #A
    #B
    #C
    #D
    Explanation:
    Without the virtual keyword, a function cannot be overridden in derived contracts. This breaks the override chain and prevents proper polymorphic behavior in multiple inheritance scenarios.

    Why can abi.encodePacked cause issues?

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

    #A
    #B
    #C
    #D
    Explanation:
    encodePacked removes padding, which can produce identical byte sequences for different inputs. When combined with hashing, this may cause collisions. Using abi.encode is safer for multi-field data.

    What does “state shadowing” indicate in inheritance?

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

    #A
    #B
    #C
    #D
    Explanation:
    State shadowing happens when a derived contract redeclares a state variable with the same name as a parent. This creates storage misalignment and unexpected slot overwrites. Auditors treat this as a major upgradeability and correctness risk.

    #A

    #A
    #B
    #C
    #D
    Explanation:
    MSTORE triggers memory expansion when writing to higher memory slots. Memory grows quadratically, so developers must understand how loops and large arrays impact gas.

    #A
    #B
    #C
    #D
    Explanation:
    If the constructor reverts, the entire deployment fails and no contract is created. This prevents partially-initialized smart contracts from being pushed on-chain

    #C
    #D
    Explanation:
    EXTCODEHASH returns the hash of a contract’s deployed bytecode, allowing detection of code changes or empty accounts. Auditors use it to verify contract identity and defend against unexpected contract replacement patterns
