One way is to have an Interface Definition Language and rely on an IDL compiler to write the interfaces in the language of your choice. Senders and receivers will expect the same types to be marshalled/unmarshalled. If a sender attempts to send data that is different from the interface, either the compiler will catch it, or hopefully a runtime error will happen - either the sender will fail to marshal the data, or the receiver will fail to unmarshal it. Still, there are "garbage-in, garbage-out" situations that someone will have to debug, but starting with well-defined interfaces and tooling to generate code helps a lot.
