FrenFlow is the first non-native interface for HIP-4 outcome markets on Hyperliquid HyperCore. Deposit USDC on Arbitrum, skip the unifiedAccount and USDH wrap steps, and trade the live BTC daily binary in seconds.

Every order routes through Hyperliquid's L1 order book with FrenFlow attached as the builder code. Same fills the native UI sees — plus our trade panel, charts and order history.
Send USDC on Arbitrum to your deposit address. FrenFlow handles the unifiedAccount flip and the USDC→USDH peg swap on @230 before the order — you trade outcomes, not infra.
HIP-4 positions land in the same portfolio view as Polymarket, Kalshi and Predict.fun. Share trades, follow leaders, and watch fills push live over WebSocket.
Real on-chain outcomes pulled from HyperCore. Click any card to open the unified trade panel — order book, fills, position tracking, all attached to the live market.
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 level, a macro print, a sports result. Because they run on HyperCore instead of a separate chain or AMM, you can hedge a perpetual position with an outcome contract in the same margin account.
Long ETH perp + bearish outcome contract in one account. No bridges, no separate collateral pools.
Maximum loss is your stake. No liquidation surprises on binary outcome contracts.
HIP-4 is rolling out in phases: curated official markets first, permissionless builder deployment later.
On-chain matching with CEX-grade latency. No AMMs, no off-chain matching servers to trust.
HIP-4 is Hyperliquid's framework for outcome markets — fully collateralized binary contracts that settle at 0 or 1 against a real-world event, running natively on the HyperCore order book. The first live mainnet outcome is a recurring daily BTC binary that settles at 06:00 UTC.
On FrenFlow, deposit USDC on Arbitrum to the Bridge2 address. FrenFlow handles the unifiedAccount flip and the USDC→USDH peg swap automatically; orders are then placed on HyperCore with FrenFlow as the builder code, against the same order book the native UI uses.
Polymarket runs a CLOB on Polygon with USDC collateral and curated markets. HIP-4 runs binary outcomes natively on Hyperliquid's L1 in the same margin account as perpetuals, which means a HYPE perp position and a related outcome can be hedged without bridging.
