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.
