**[Announcement from OKX Regarding the Activation of the Price Protection Mechanism for RWA Token Index]** To mitigate market risks, OKX plans to activate the price protection mechanism for the RWA (Real-world Asset) token index on November 6, 2025. The specific rules are as follows: RWA token index final price = Clamp[RWA token index price, corresponding real asset price × (1 + X), corresponding real asset price × (1 – X)]. The final price of the RWA token index will be restricted within the range of [corresponding real asset price × (1 + X), corresponding real asset price × (1 – X)]. Taking the XAUT/USD index as an example, assuming the parameter X is set at 10%, and the real asset price is the XAU/USD index, the calculation process after activation can be referenced as follows: The platform will obtain the corresponding real asset price of RWA from multiple data sources. For index calculation logic, refer to: Index Calculation Rules. Please note: At this stage, the platform will activate price protection for the XAUT/USDT and XAUT/USD indices, with the parameter X set at 10%. The platform may activate protection for more RWA indices, disable protection, or adjust relevant parameters based on market conditions. Such adjustments will not be separately notified.
