Which keyword prevents a state variable from being modified after deployment construction?

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

#A

#B

#C

#D

Explanation:
immutable variables are assigned once (typically in the constructor) and then become read-only. They are stored in bytecode rather than regular storage slots, which can reduce gas compared to storage reads. This matters in Solidity interviews because immutables are common in optimized contracts (e.g., router addresses) and in secure configuration patterns.

Which storage type enables EIP-1167 minimal clones to be cheap?

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

#A

#B

#C

#D

Explanation:
Minimal proxy clones (EIP-1167) keep logic in an implementation and rely on proxy bytecode forwarding calls, making deployment cheap. In practice, immutables in the implementation help keep runtime reads efficient and reduce repeated storage reads for configuration-like values. Candidates are often tested on why clones save gas and how configuration is safely handled.

Which pattern most directly reduces reentrancy risk on external transfers?

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

#A

#B

#C

#D

Explanation:
The Checks-Effects-Interactions (CEI) pattern reduces reentrancy by making you validate inputs and update internal state before any external call (like ETH transfer or token transfer). If a malicious contract re-enters, state has already moved forward, limiting exploitability. Many interviewers treat CEI as a must-know Solidity security habit for production contracts

In EVM, which opcode can silently fail and return a boolean instead of reverting?

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

#A

#B

#C

#D

Explanation:
Low-level CALL (and friends like DELEGATECALL) returns a success flag rather than automatically bubbling a revert. If you don’t check that boolean (or decode return data properly), your contract may continue in a “success-looking” state while the external call actually failed. This is a classic Solidity audit finding tied to unsafe external interactions.
