Bittrex is upgrading the Hedera Hashgraph (HBAR) wallet to a memo format on 6/9/2022, and will deprecate existing deposit addresses.
There will be brief wallet downtime at 10:00 AM PT on 6/9/2022 while we conduct wallet maintenance. During that time, the HBAR wallet will be disabled such that deposits and withdrawals will be paused. We will resume wallet functionality once the upgrade is complete.
Token balances will not change during this time and trading will continue as normal on those coins' markets.
After wallets are re-enabled, users will need to regenerate new addresses for those tokens. See our article titled 'Crypto Deposits for more information on generating a new deposit address. Assets transferred to old token addresses will not be credited to your account.
