Please make sure all proper assigns have been set. If this
is a child template, ensure assigns are given explicitly by
the parent template as they are not automatically forwarded.

Available assigns: [:conn, :current_path, :token, :total_token_holders, :total_token_transfers, :view_module, :view_template]
