-The package will be a standalone package with no relay dependencies, its own mirror node client implementation and its own cache service conncting to redis.
-This allows for a more modular and scalable solution, with the ability to easily add more endpoints in the future.
+The package will be a standalone package, but will be using the existing relay package for service implementations.
