What is the most direct risk of “unbounded loops” in on-chain code?

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

#A

#B

#C

#D

Explanation:
Unbounded loops can make functions exceed block gas limits as state grows, permanently preventing execution—classic denial of service. This is common in airdrop distributions, iterating holders, or clearing arrays. Security interviews test this because it’s a real production failure: “worked in tests” but becomes uncallable at scale. Mitigations include batching/pagination and off-chain indexing.

Which bug class is most associated with incorrect upgradeable storage layout?

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

#A

#B

#C

#D

Explanation:
In upgradeable contracts, the proxy holds storage while the implementation code changes. If developers reorder variables or change types, storage slots map incorrectly—corrupting balances, roles, or critical pointers. This is a high-severity issue in audits. Interviewers expect candidates to mention append-only storage layout, storage gaps, and standards like EIP-1967 for proxy slots.

What is the core risk of using tx.origin for authorization?

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

#A

#B

#C

#D

Explanation:
tx.origin authorization can be bypassed if a user is tricked into calling an attacker contract, which then calls the target contract—tx.origin remains the user. This is a known insecure pattern in Ethereum security. Interviewers like it because it tests whether candidates understand call chains and why msg.sender + explicit access control is the correct boundary.
