The Ethereum network will be undergoing a scheduled upgrade at block number 9,069,000, which is predicted to occur on Saturday, December 7, 2019. The exact date is subject to change due to variable block times and timezones.
To support the upgrade, deposits and withdrawals of ERC20 tokens in XWallet will be temporarily unavailable from 17:00 GMT+8 on December 6, including ETH, DAI, DGX, KCS, KNC, VRH, FX, ENQ, IDRT, XDB and NPXS. Transactions within XPOS, XWallet and XPASS cards will not affected during the upgrade.
Please note that this upgrade will not result in generating new tokens. The amount you hold in XWallet will remain the same and you do not need to do anything about it.
We will re-open deposits and withdrawals for ERC20 tokens as soon as the network is stabilized. Announcement across our communication channels (Twitter, Facebook and XWallet user notification center) will be made to notify the XWallet users.
