Bittrex will be moving to a single account address for UST, KRT, and SDT. Existing addresses will be deprecated by 2/18/2022, 12:00 PM PT. Your new address for UST, KRT, and SDT will be the same as your LUNA address.
Please do not deposit any UST, KRT or SDT until you have generated your new address. Assets deposited to your old address(es) will not be credited to your account.
If you have any questions or need assistance, you can open a ticket at http://support.bittrex.com.
