According to CoinMeta, Wu said that hyperliquid has announced that it will add an optional licensing market feature (hip-3) for hip-3 in future network upgrades. Once enabled, market deployers or their sub-deployers will be able to manage the on-chain whitelist, restricting participants in specific markets. This feature is an optional extension for hip-3 and will not change existing markets. Currently, the initial version of hip-3 * has been launched on the test network, and hyperliquid indicates that this feature is designed to help deployers operate their markets in accordance with applicable regulatory requirements.
