Answer Example

I ensure security by conducting thorough smart contract audits using tools like OpenZeppelin and working with third-party auditors. To address scalability, I explore layer-2 solutions like Optimism or Arbitrum and implement off-chain data management when appropriate. For example, while developing a decentralized oracle solution, I combined advanced encryption techniques with a layer-2 network, increasing transaction throughput by 50% without compromising security. Regular stress testing and monitoring further ensure the product can scale securely as user demand grows.
