OKX Announcement on Polygon Network Upgrade

We will support the Polygon network upgrade. To ensure the upgrade proceeds smoothly, please take note of the following arrangements: Suspension Time: Starting from 21:00 (UTC+8) on July 2, 2026, deposit and withdrawal services for all tokens on the Polygon network will be suspended. Service Resumption: After the network upgrade is completed, we will resume deposit and withdrawal services once the network operates stably, without further notice. No Action Required: If you hold relevant tokens in your account, no action is required during the network upgrade period. Please Note: - Trading Unaffected: Trading of relevant tokens will proceed as usual. However, please be aware of the potential risks in spot, margin, and derivatives trading of the relevant tokens, and consider increasing your margin in advance to mitigate risks. - Fund Safety: Please refrain from conducting deposit or withdrawal operations for the relevant tokens during the network upgrade period to avoid potential fund losses.
