    Which audit issue is most often downgraded incorrectly?

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

    #A
    #B
    #C
    #D
    Explanation:
    Front-running is often downgraded incorrectly in smart contract audits because teams underestimate MEV and mempool-based exploitability. In DeFi security, transaction ordering attacks can cause repeated economic loss even without a classic code exploit.

    Which finding has highest real-world exploit probability?

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

    #A
    #B
    #C
    #D
    Explanation:
    Access control bugs often have the highest real-world exploit probability in smart contracts because attackers can directly call privileged functions when role checks fail. In blockchain security audits, broken authorization logic is a common cause of fund loss and protocol takeover.
