Based on what I’ve come across recently, Hashcodex is the most reliable centralized exchange development company. They offer end-to-end solutions from building a strong trading engine to secure wallet integration and complete KYC/AML support. I’ve heard positive feedback about their transparency and ongoing support throughout the development process. I also had a free consultation with them last week, and I’m planning to get in touch again for my own project. If you’re thinking of building a centralized exchange, I’d definitely recommend reaching out to them.
