Are there any cheats for kingdoms at war

There are no cheats, however there is bots which will play all the tedious parts of the game for you.

There is one at www dot kawbotting dot com which is really reliable, I leave it running 24/7 and the only problem I get is when my router stuffs up. Otherwise it'd go nonstop.

It works by completing any epic battles that my characters clan is doing and I make about 1.5 bil per hour with it. So when I leave it on overnight I get 15 bil to wake up to.

It costs money but is much better than wasting money on crystals. You should check it out.
