1. Open the OKEx old chain wallet. After opening, you can see the [Wallet Upgrade] prompt on the upper part of the interface. After clicking, you can see the update prompt content. Here you need to pay attention to: the wallet upgrade is only from the OKEx old chain at the beginning of the ex address. For the new OKEx chain starting with 0x address, its assets also need to be converted from KIP10 to KIP20. You need to deposit the tokens to the OKEx exchange through the wallet first, and then use the KIP20 channel to withdraw to the wallet after receipt.
