OKEX-ERC-20-Tokens-Deposit-Suspended

Dear valued customers,

We are suspending the deposits of all ERC-20 tokens due to the discovery of a new smart contract bug - "BatchOverFlow". By exploiting the bug, attackers can generate an extremely large amount of tokens, and deposit them into a normal address. This makes many of the ERC-20 tokens vulnerable to price manipulations of the attackers.

To protect public interest, we have decided to suspend the deposits of all ERC-20 tokens until the bug is fixed. Also, we have contacted the affected token teams to conduct investigation and take necessary measures to prevent the attack.

If you have already made a deposit request, your funds will arrive safely after our deposit service resumed. We apologize for any inconvenience caused.

Regards,
OKEx
