What are the ethical considerations of working as a smart contract developer for a controversial DeFi protocol?

Hey folks,
I’ve been in the smart contract space for a while, and recently got approached about working on a DeFi project that, let’s just say, has a pretty “mixed” reputation. It got me thinking—where do you all draw the line when it comes to smart contract ethics? Is there an actual checklist you run through, or do you go more on gut feeling?

A few (maybe messy) questions rattling around in my brain:

When you’re picking a blockchain career path, how do you decide if a DeFi project is “sketchy” or just “cutting-edge”?
What does acting responsibly even mean in crypto? We talk a lot about responsible innovation, but sometimes it feels like everyone’s faking it till they make it.
If you see ethical red flags (like, say, anonymous teams or incentives that feel off), do you talk about it openly with your team? Take it public? Or just bail?
Have you ever had to ignore your spidey-sense because you really needed the gig, or did you walk away? Would love to hear some real stories.
Where do you personally draw the line as a developer between “move fast and break things” and “maybe this is actually harmful”?

Sorry for the brain dump, just looking to hear how other devs in the trenches deal with these DeFi ethics dilemmas. Honest takes, war stories, even regrets all welcome!

Thanks in advance—curious what people really think.

If your gut says something’s off, it probably is. I’ve lost count of how many “groundbreaking” DeFi projects I’ve seen that turned out to be smoke and mirrors—anonymous teams, tokenomics that make zero sense for anyone except the early whales, marketing that pushes FOMO over fundamentals. Most of the time, the warning signs are right there if you look past the hype.

My real checklist? Are the core contributors public and actually interacting with the community? Is there a real audit from someone I’ve heard of, not just a PDF on Github? Are decisions discussed in the open, or are things quietly pushed by a handful of insiders? Most importantly—would I put my own funds in, or tell a friend to? If the answer’s no, I’m out.

I’ve raised red flags internally before, sometimes it led to changes and sometimes I realized I was just around for the optics and walked away. Been offered solid $$ to ship code for projects I wouldn’t use myself—always said no, because your reputation is way harder to rebuild than your bank balance.

Anyone else ever taken a chance and regretted it? Or actually made a difference in a grey-area project? Let’s get some honest experiences out there.
