BlockBeats News, July 27th, the Hyperliquid testnet recently introduced a new feature named "stars." This feature has introduced an optional transaction whitelist mechanism for the HIP-3 DEX, allowing deployers to restrict opening positions or adding to positions to only whitelisted addresses. Currently, the testnet whitelist has a maximum capacity of 10,000 addresses, while unauthorized addresses can still deposit into accounts and submit only reduction-only orders to close positions or decrease existing positions.
Community analysis believes that this feature is expected to expand the application scenarios of the HIP-3 DEX. For example, tokenized stocks, real-world assets (RWA), institutional indices, and other regulated products can use the address whitelist to only allow trading for users who have completed identity verification (KYC) or meet admission requirements. At the same time, new markets can first open testing to market makers, partners, or community members to reduce the initial market's risk of encountering wash trading, front running, or malicious manipulation. The design that allows non-whitelisted users to continue reducing positions also avoids users being unable to exit positions due to permission restrictions.
Furthermore, the "stars" feature has not altered the permissionless nature of the Hyperliquid base layer but has added an optional access control feature on top of it, which developers can enable or disable as needed. This means that scenarios such as DAOs, trading clubs, private equity funds, or partner-exclusive markets can build closed trading markets with admission mechanisms while maintaining the advantages of the Hyperliquid matching engine and settlement layer. Currently, this feature is still in the testnet phase, and the official team has not yet disclosed its specific use case. The future application scenarios are still pending confirmation upon the mainnet launch and further developer documentation.
