Update
We have re-enabled withdrawals for Ethereum Classic (ETC) and all pending withdrawals have now been processed. Deposits will remain offline however we have credited all deposits that had been pending. Any further deposits will not be credited until we re-enable depositing again. We are continuing to monitor the Ethereum Classic blockchain and will bring deposits back online once we believe it is safe to do so.

Thank you.

Identified
Due to a potential 51% attack on the Ethereum Classic network, we have temporarily increased the number of confirmations required for ETC deposits to 500 (roughly 1 hour and 56 minutes). We will continue to monitor the situation and lower it back to 120 confirmations once our developers believe it is safe to do so.
