Bittrex is supporting the Haven Protocol (XHV) upgrade to Monero v0.16 by supporting the hard fork at block height 741,957 or approximately 6:30 AM PST on December 8, 2020.
Payment IDs were deprecated by Monero and therefore Haven Payment IDs will be deprecated as well. Bittrex will be switching to the same model as Monero, and memos are no longer supported.
NOTE: Users will need to generate new XHV deposit addresses before depositing funds.
Haven Protocol wallets have been closed for deposits and withdrawals. Bittrex will re-enable the XHV wallet when we deem the upgrade is satisfactory. Trading will continue as normal during this time.
We would like to thank the Haven Protocol team for working closely with us.
