Don’t be fooled by a fancy website. A shiny homepage is not a good sign of good technology. So focus on what they actually build, not how beautifully it’s advertised.

Look at real work, not fiction. Request their portfolio. Do they come with live exchanges? Or are they rebranding an old script?

Get to know their product. Do they offer a full suite of services like UI, wallet integration, admin panels, KYC/AML, liquidity provisioning, and security framework, or do they just offer a simple copy of what they have and say good luck?

Test the demo. When it starts slower than dial-up or freezes with a single click, get out as quickly as you can.

Talk to their customers. It’s a good idea to read reviews, and it’s a good idea to get feedback directly. If they’re hesitant to provide feedback, that’s a bad thing.

Effective communication is key. The best cryptocurrency exchange development services won’t bury you in a web of words. They’ll tell you the truth.

Develop total coverage. Not everything which are cheap is good. If something sounds too good to be true, it probably is.
