**[OKX Announcement Regarding Base Network Upgrade]** We will support the Base network upgrade. To ensure the upgrade proceeds smoothly, please take note of the following arrangements: **Suspension Time:** Starting from May 29, 2026, 01:00 (UTC+8), deposit and withdrawal services for all tokens on the Base network will be temporarily 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 ETH 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 derivatives trading of these tokens, and consider increasing your margin in advance to mitigate risks. - **Fund Safety:** Avoid performing deposit or withdrawal operations for related tokens during the network upgrade period to prevent potential fund losses. For more information, please refer to the project team's announcement. **OKX Team** May 22, 2026
