Isn't WhatsApp an Erlang app?

Whatsapp is both a server and a client. The server might be written in Erlang, but the client (where all the end-to-end encryption happens) is written in whatever the device can run.

The device runs machine code. Client code can be written in any language which can be either compiled or interpreted to machine code.

Android devices run Java, with an option for machine code for some functionality.

The socket layer at OS-level is written in C and Erlang probably uses an SSL library written in C. Turtles all the way down!

WhatsApp uses Erlang and various other languages. I doubt the encryption code is in Erlang. Erlang can call C code.
