OKX Announcement Regarding Sui Network Upgrade

We will support the Sui Network upgrade. To ensure the upgrade proceeds smoothly, please take note of the following arrangements: **Suspension Time:** Starting from May 22, 2026, 02:00 (UTC+8), deposit and withdrawal services for all tokens on the Sui Network will be suspended. **Service Resumption:** After the network upgrade is completed, we will resume deposit and withdrawal services once the network is operating stably, without further notice. **No Action Required:** If you hold Sui Network tokens or other related tokens within the network in your account, no action is required during the network upgrade period. **Please Note:** - **Trading Unaffected:** Trading of related tokens will proceed as usual. However, please be aware of the potential risks associated with spot, margin, and derivative trading of these tokens, and increase your margin in advance to mitigate risks. - **Fund Safety:** Do not perform deposit or withdrawal operations for related tokens during the network upgrade period to avoid potential fund losses. For more information, please refer to the project team's announcement. OKX Team May 21, 2026
