 This section is optional, as developers are free to choose their dependency manager and project building method. That said, the current most used framework for versioning control is [`go.mod`](https://github.com/golang/go/wiki/Modules). It ensures each of the libraries used throughout the application are imported with the correct version. See an example from the [nameservice tutorial](https://github.com/cosmos/sdk-tutorials/tree/master/nameservice):

 Another interface through which users can make queries, introduced in Cosmos SDK v0.40, is [gRPC](https://grpc.io) requests to a [gRPC server](../core/grpc_rest.md#grpc-server). The endpoints are defined as [Protocol Buffers](https://developers.google.com/protocol-buffers) service methods inside `.proto` files, written in Protobuf's own language-agnostic interface definition language (IDL). The Protobuf ecosystem developed tools for code-generation from `*.proto` files into various languages. These tools allow to build gRPC clients easily.
 
 One such tool is [grpcurl](https://github.com/fullstorydev/grpcurl), and a gRPC request for `MyQuery` using this client looks like:

 Cosmos SDK v0.40 introduced Protobuf as the main [encoding](./encoding) library, and this brings a wide range of Protobuf-based tools that can be plugged into the SDK. One such tool is [gRPC](https://grpc.io), a modern open source high performance RPC framework that has decent client support in several languages.
 
 Each module exposes [`Msg` and `Query` Protobuf services](../building-modules/messages-and-queries.md) to define state transitions and state queries. These services are hooked up to gRPC via the following function inside the application:
