Most crypto platforms have support that either ignores you or pastes boilerplate. I sent Unity Exchange a specific question about how their smart contracts handle edge cases during low-liquidity events — the kind of question that reveals whether a team actually understands their own product. The response came back in under four hours, was technically coherent, and referenced their actual contract logic. That alone moved them up in my mental ranking. Product quality and team responsiveness don't always correlate, but when they do it's a good sign. Still doing due diligence on the security audit history before committing real capital, but the first impression on Unity Exchange is better than most.
