[Hyperliquid to Launch Portfolio Margin System, Now Live on Testnet] According to Hyperliquid's announcement, the on-chain portfolio margin system is set to launch and is now live in the pre-alpha phase on the testnet. This mechanism unifies users' spot and perpetual trading accounts, achieving higher capital efficiency and automatically generating yield on unused borrowable assets. Initially, only USDC will be borrowable, with HYPE as the sole collateral. Subsequent updates will support assets such as USDH and BTC. Users can utilize a single account for collateral arbitrage, offsetting PnL, and reducing liquidation risks. This upgrade also involves deep collaboration with the lending protocol within the HyperEVM ecosystem.
