What’s the goal of invariant testing in Solidity QA?

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

#A

#B

#C

#D

Explanation:
Invariant testing in Solidity focuses on proving that certain properties of a smart contract always hold true, no matter what inputs or transactions occur. These tests run random sequences of actions to check if core rules — like balance consistency, ownership logic, or access permissions — ever break. By doing this, developers can find deep logical bugs or regressions that normal unit tests might miss. It’s one of the most reliable QA methods to ensure contract integrity and security over time.

Which on-chain action best signals real user adoption?

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

#A

#B

#C

#D

Explanation:
Sustained transaction frequency shows that users are consistently finding real value in a blockchain product, not just testing it temporarily. It’s a strong Tier-3 proof of product-market fit because it reflects ongoing user trust, retention, and organic demand—far more meaningful than vanity metrics like token price or social media hype.
