DOGE COIN BOT - Wallet with less Commissions?

I have a bot that I am testing that is doing okay but the commissions are eating up most of my profits. I read somewhere, but lost the link to the article, that if you use some other wallet provider that the commissions can be lowered. Does anyone know about this wallet or has anyone heard of what I am talking about here? Any advice would be greatly appreciated. Before I put a substantial amount on the line I would like to see if I can improve the rake. Thanks
