As soon as Saturn DAO is activated we will transfer the whole wallet balance to the DAO smart contracts. You can track current fees wallet balance here.
At the time of writing, there is about 21 ETH and 96 ETC in fees collected by Saturn Protocol v1. However, it is worth noting that as trading activity is lately growing at unprecedented speed, so do the fees collected, so you can expect that right from the get-go we will see some interesting discussions on how to best spend this money in order to benefit the DAO.
If you have plans to put forth a proposal to Saturn DAO, now would probably be a great time to start making your ideas and presence known on our Discord or Forum.
