  • Anyone here moved from regular QA to Blockchain QA? I’m trying to understand what actually changes

    I’ve been working in regular QA for about six years — mostly white-box, API testing, and some automation. I’m now thinking about moving into Blockchain QA, but I can’t figure out how different the actual work is.

    Some people say “QA is QA, no big change,” while others say it’s a completely different mindset because you’re dealing with contract logic, state changes, invariants, and things that can’t be “rolled back.”

    I’m confused about what really changes in the day-to-day:

    • Do you spend more time reading code?

    • Do you need to know Solidity before applying?

    • How different are the tools from regular QA?

    • Is it closer to testing, or closer to auditing?

    I don’t want to jump into something I can’t handle or misunderstand.
    If you moved from a normal QA job into blockchain work, it would help me understand what the shift actually feels like.

    Thanks in advance.

    I moved into blockchain QA about a year ago after five years in regular QA. The biggest change for me was what I’m testing, not how I think about testing.

    In blockchain, you spend more time checking how data changes in the contract. For example, if someone deposits tokens, you check if the values update exactly the way they should. And then you check what happens if the user does the same action again or does it in a different order.

    I didn’t start by learning full Solidity. I took a simple ERC20 contract and wrote small tests using Foundry. When something failed, I looked at the code to understand why. That taught me more than any tutorial.

    My first job came because I had a small GitHub repo with basic tests. It was not perfect at all, but it showed I understood how contract behaviour works.

    The day-to-day feels more “logical checking” than UI or workflow testing.

    From a developer’s point of view, the QA people who do well in blockchain are the ones who can explain what must stay correct every time a function runs.

    For example:
    If a contract increases a user’s balance, then that balance should never go negative, never jump unexpectedly, and should always match the actions taken. A lot of bugs come from the order in which things are called or from forgetting to update a value.

    We don’t expect QA candidates to know advanced Solidity. What we look for is simple reasoning like:

    • “If this value depends on another function, what happens if the other function fails?”

    • “If someone calls this twice, does the logic still hold?”

    If you can think in that way, you’ll fit in easily. Blockchain QA is less about clicking around and more about checking contract behaviour step by step.

    I started in QA, moved into blockchain QA, and later into security. One thing I’ll say upfront: you do spend more time reading code here. Not advanced code, but enough to understand what should or shouldn’t happen.

    What surprised me is how small the codebases are. You’re often testing just a few functions, but they interact in ways that can break the whole system if the logic is wrong.

    What helped me learn was reading old audit reports and then trying to reproduce those issues. You quickly understand common mistakes like missing checks, wrong order of operations, or values not updating correctly.

    You don’t need a big automation setup. Teams mainly care about your ability to say:
    “This function should only work under these conditions — let me test those conditions.”

    If you enjoy debugging and thinking through logic, the switch is very doable.

    If you want real-world practice, pick a GitHub issue from a DeFi project and try reproducing it. That teaches you how blockchain bugs appear in the wild.

    Seeing the replies here, there’s a clear pattern: most people began by testing one small contract and learning how its values changed in different situations. That seems to be the fastest way to understand what actually changes in Blockchain QA.

    For anyone exploring this path, our QA Testing Hub collects a few starter patterns and simple examples: 👉 https://artofblockchain.club/discussion/smart-contract-qa-testing-hub

    If debugging feels confusing, this discussion explains how developers trace issues step by step: 👉 https://artofblockchain.club/discussion/debugging-smart-contracts-is-tough-how-do-you-make-it-easier

    And for interview preparation, we have a hub that covers the reasoning-type questions teams usually ask: 👉 httpsartofblockchain.club/discussion/smart-contract-interview-prep-hub

    If anyone has early test repos or practice notes from their own transition, feel free to share them here — it helps others see what the starting point looks like.
