According to the upgrade process of the Ethereum (ETH) Constantinople/St. Petersburg hard forks released by the developer, the upgrade have been set to block number 7,280,000, which is expected to be on February 28, 2019, but depends on the actual block height. To ensure a smooth upgrade, we will suspend deposits & withdrawals of Ethereum (ETH), 0x (ZRX) and DATA (DTA) at 9AM on February 28, 2019 PST. The resumption time will be notified via announcements, and we apologize for the inconvenience caused during the suspension.

If any new coins are created during the upgrade, we will distributed to users.
