Cryptal will be updated to support the Ethereum (ETH) network upgrade, set to take place at Ethereum block 15,050,000. The actual upgrade is expected to take place on June 29, 2022.

To prepare for this upgrade, withdrawals of ETH and all ERC20 network tokens will be unavailable as of Wednesday, June 29, 2022 at 7:45 UTC. Withdrawals will resume after the upgrade when the network is stable.

Trading will not be affected and no action is necessary on your part, however we recommend that you avoid making deposits within the 2 hours before and after the actual upgrade. 

Note that BEP20 deposits and withdrawals are available and will continue uninterrupted.
