    I’ve started building my first few smart contracts and use Hardhat for testing. But every time something fails, I just keep adding console.log everywhere until it magically works. It feels messy and I’m never sure why it failed in the first place.

    I’ve heard seniors say debugging is about validating state changes, not just reading logs — but I don’t fully get how to do that. How do you all actually debug smart contracts efficiently? What routine or habit helped you stop chasing ghosts in tests?

    When I talk about Push vs. Pull during interviews, I try to frame it in business-friendly terms instead of just technical jargon.

    I usually explain it like this:

    In a Push model, the contract automatically sends (or “pushes”) funds or data to another party. This means the transfer is initiated by the system itself, which creates a larger attack surface — there are more ways things could go wrong or be exploited.

    In a Pull model, on the other hand, the user initiates the action — they “pull” their funds or data by requesting it. The contract’s job is to validate everything carefully before completing the transfer. This approach tends to be safer and easier to reason about from both a security and product perspective.

    When I explain it this way, hiring managers usually nod instead of zoning out. It connects the technical concept to risk management and user trust, which are things business leaders care about. It shows that I’m not just thinking about writing code — I’m thinking about building safer, more reliable products that protect users and the company’s reputation.
