Top Interview Questions & Answers

Q1: What is a Reentrancy attack in Solidity and how do you prevent it?

A reentrancy attack occurs when an external malicious contract calls back into the calling contract before the initial state balance is updated. It is prevented by using the Checks-Effects-Interactions pattern and OpenZeppelin ReentrancyGuard.

Frequently Asked Questions

Is Web3 development only about cryptocurrency speculation?

No. Web3 engineering is used in supply chain traceability, decentralized identity (DID), tokenized real estate, and verifiable credentials.
