Hyperliquid: HIP-4 launches on testnet, plans to launch a one-day binary prediction market for BTC and HYPE.

CoinFeed reported on March 11 that Hyperliquid announced the official launch of HIP-4 on its testnet. The first batch of outcome markets launched are periodic binary options based on the HyperCore mark price. Users can view these markets in the "Predict" section of the testnet interface. Outcome contracts are fully collateralized, settled within a fixed price range, and feature non-linear payouts and expiration times, without leverage or liquidation mechanisms. Hyperliquid also stated that it plans to launch a one-day expiration binary market for BTC and HYPE in the future. The protocol is designed to support multi-outcome markets, but this feature is not yet included in the initial launch plan.
