Pump.fun said on Nov. 10 that its Hyperliquid-powered perpetual futures service now supports limit orders, time-weighted average price (TWAP) execution, cross margin and adding or removing margin on open positions. Cross margin allows traders to share collateral across positions, meaning losses from one trade can reduce the margin available to support others. The Solana memecoin launchpad launched the service on Oct. 28, offering exposure to crypto, stocks and commodities. Its launch thread advertised more than 300 Hyperliquid markets and isolated margin, which confines collateral and liquidation risk to an individual position.
