Out of the box CSRF tokens have been available for Padrino since the 0.11.0 release and was given an handy update in the 0.11.4 release. It can be a bit difficult to find the actual information and documentation on how to use CSRF tokens in Padrino. It is very straight forward, just add <%= csrf_meta_tags %> inside your head tag like this minimal example.

<!DOCTYPE html>
        <title>Padrino App</title>
        <%= csrf_meta_tags %>
<%= yield %>
