Quantum Resistant Ledger (QRL) will be upgrading their blockchain from an Ethereum ERC20 token to a new mainnet Proof of Work blockchain utilizing the Cryptonight v7 consensus algorithm, backed by provably secure, peer-reviewed XMSS cryptography (instead of 256-bit ECDSA). 

All Quantum Resistant Ledger users will retain the balance of their QRL addresses, which will be migrated to the new blockchain. 

Users' QRL Bittrex exchange balance totals will reflect the same total that they had prior to the swap in a 1:1 manner.  Once the swap is complete, all tokens from the old blockchain will no longer be supported or traded on Bittrex. 

Bittrex will re-enable the Quantum Resistant Ledger (QRL) wallet when we and the Quantum Resistant Ledger team agree that the migration is satisfactory. 

Note: Bittrex will be closing our QRL wallet on 12/4/2018 and may stop trading the token to take accurate snapshots of balances.  If any QRL deposits you had sent to Bittrex are not settled (e.g. marked as pending) by 6:00 PM PT, on 12/4/2018 (2:00 AM on 12/5/2018 UTC), you may not be credited with QRL. 

We would like to thank the Quantum Resistant Ledger team for working closely with us.
