Bittrex has completed swapping Hydro (HYDRO) to a new ERC20 contract 0x946112efab61c3636cbd52de2e1392d7a75a6f01.
User's HYDRO exchange balance totals reflect the same total that they had prior to the swap in a 100:1 manner (i.e. users with 100 pre-swap HYDRO now have 1 post-swap HYDRO). The old HYDRO tokens are no longer supported or traded on Bittrex.
We would like to thank the Hydro team for working closely with us.
