With most developers taking advantage of new tokens for purchase, advertising, and rewards in the app, the lack of interoperability between dApp is inevitable. Anyway, hopefully the project develops in the right direction!
However, with the emergence of different blockchain platforms, neither blockchain nor a single blockchain developer is arriving at a consensus over using a blockchain platform for building their dapps.
Each and every business wants to develop a Dapp on such a platform, which provides the lightning fast transaction speed with security and zero fees along with providing an option to migrate from one blockchain app development platform to another as per their business vision and need.
