    How to Explain Your Smart Contract Architecture Decisions Without Sounding Vague or Theoretical

    There is one moment in almost every Solidity interview when everything becomes quiet. You finish describing your solution, and the interviewer asks:“Why did you design it this way?”This one question decides more outcomes than people realize. Many candidates freeze — not because their design is...

    Why should developers avoid using tx.origin for authentication?

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

    #A
    #B
    #C
    #D
    Explanation:
    Attackers can trick users into calling a malicious contract. That contract then makes a call where tx.origin equals the victim’s address. This bypasses access control and leads to unauthorized actions.

    Why are fallback functions dangerous?

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

    #A
    #B
    #C
    #D
    Explanation:
    Fallback functions run automatically when unknown calls or plain ETH are sent. If they contain external calls or heavy logic, attackers can trigger recursion or re-entrancy. They must be kept minimal and safe.

    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.
