The evidence strongly supports the statement. Three separate, high-authority news outlets (The Block, a report on TradingView, and Cryptopolitan) all corroborate that Hyperliquid activated or launched its HIP-3 upgrade around October 13, 2025. These sources specifically state that this upgrade enables "permissionless perp market creation" and "builder-generated markets," which is the core function of HIP-3. The reports from The Block and TradingView cite the project's official Discord announcement as their primary source, adding significant credibility. While some lower-authority sources are merely explanatory and do not confirm the launch event, they do not contradict the primary news reports. There is no conflicting evidence suggesting the launch did not occur. The phrase "on its frontend platform" is a reasonable inference, as a public launch of a user-facing feature like permissionless market creation on a decentralized exchange would necessarily involve integration with the user interface. The collective weight and consistency of the high-quality sources make the statement highly probable.
