Hyperliquid's HIP-4 upgrade introduces outcome trading — fully collateralized binary contracts that settle on HyperCore. FrenFlow plans to add Hyperliquid support when HIP-4 reaches mainnet, alongside the Polymarket, Kalshi and Predict.fun integrations that are live today.

HIP-4 adds fully collateralized, binary contracts to Hyperliquid's L1. Each contract settles at either 0 or 1 based on a pre-defined event — a Bitcoin price milestone, a macro print, a sports result. Because they run on HyperCore instead of a separate chain or AMM, you can hedge a perpetual long with a downside outcome in the same margin account.
Long ETH perp + bearish outcome contract in one account. No bridges, no separate collateral pools.
Your maximum loss is always your stake. No liquidation surprises on binary contracts.
HIP-4 is expected to launch in two phases: curated official markets first, permissionless builder deployment later — following the pattern HIP-3 used for perpetuals.
On-chain matching with CEX-grade latency — no AMMs, no off-chain matching servers to trust.
FrenFlow already routes across Polymarket, Kalshi and Predict.fun from a single trading modal. Hyperliquid support is on the roadmap for HIP-4 mainnet.

Polymarket and Kalshi positions already land in a single view. The plan is to surface Hyperliquid outcome trades in the same portfolio when HIP-4 support ships.
FrenFlow runs a production copytrading engine on Polymarket. Extending the same pattern to Hyperliquid outcome markets is planned once HIP-4 is generally available.
FrenFlow service fees and Polymarket builder fees are tracked separately today. The same model would apply to Hyperliquid builder codes when integrated.
