ChainCatcher News, according to official sources, Hyperliquid has announced that the cross-margin feature for HIP-3 permissionless perpetual contracts has been enabled on the testnet, but has not yet been launched on the mainnet. However, this feature meets the criteria for the mainnet-level bug bounty program.
Deployers of HIP-3 must first enable cross-margin for a specific asset before users can trade that asset with cross-margin. Under a unified account, all cross-margin perpetual contracts using the same collateral asset can share margin, even across multiple DEXs. However, assets on different DEXs are protected to their maintenance margin levels to prevent automatic liquidation caused by significant price fluctuations on other DEXs. This new “protected cross-margin” system ensures system solvency while maintaining user experience. Cross-margin is not designed for DEX abstract interfaces, and related interfaces should not allow cross-margin trading through DEX abstraction. Users should use a unified account or pooled margin to achieve the expected behavior of HIP-3 asset cross-margin.
