A number of altcoins will be supported, but no official announcement has been made as to exactly which. The intention appears to me to be to integrate Veserus, the NVO DEX, and the wallet all into a single ecosystem, but that's just based on some of my own educated speculation and a few hints by the team.

Notably, it has been announced that their intent is that the NVST/BTC pair will be feeless for trading (normal withdrawal fees to cover blockchain fees will still be in effect, naturally)
