I’ve been diving into this topic lately, and honestly, choosing a team for blockchain app development can make or break the whole project. From my experience, the biggest factors are architecture flexibility, security audits, and how well the developers understand real-world scalability challenges. A lot of companies promise fast delivery, but only a few actually design dApps that hold up under growing user activity and complex on-chain logic. If you’ve found a solid provider, it’s worth checking how they handle smart-contract testing, node infrastructure, and long-term support.
