Although we are not for certain whether mainnet support will be implemented, it is a top priority for us and under active assessment. We are taking a "wait and see" approach due to the complexity of integrating EOS.
We need all of the assets in Exodus to work exactly the same as each other, and with EOS, there are a lot of additional features needed for users to interact with the network. We need to find a way to seamlessly integrate EOS before moving forward on this, but rest assured, we'll make a big announcement here once we have!
