[Hyperliquid Announces HIP-3 Cross-Margin Feature Now Live on Testnet] BlockBeats News, February 13, according to official sources, Hyperliquid has announced that the cross-margin feature for the HIP-3 permissionless perpetual contract market is now live on the testnet but has not yet been enabled on the mainnet. However, this feature qualifies for the mainnet-level bug bounty program. Deployers of HIP-3 must first enable cross-margin for a specific asset before users can utilize that asset for cross-margin trading. Under a unified account, all cross-margin perpetual contracts using the same collateral assets can share margin, even across multiple DEXs. However, assets on different DEXs will be protected up to their maintenance margin levels to avoid forced liquidation caused by significant price fluctuations on other DEXs. This new "protective cross-margin" system ensures the solvency of the system while maintaining a seamless user experience. Cross-margin is not designed for DEX abstraction interfaces, and related interfaces should not allow the use of cross-margin through DEX abstraction trading. Users should utilize unified accounts or portfolio margining to achieve the expected cross-margin behavior for HIP-3 assets.
