Hyperliquid Opens Testnet for Permissionless Event Markets with HIP-4 Framework

Hyperliquid has rolled out the first testnet version of its permissionless HIP-4 outcome-market framework, giving developers a playground to build and experiment with event contracts before launching them on the mainnet. This new capability lets creators use approved templates to deploy contracts centered on measurable events without needing validator approval upfront.

These HIP-4 contracts are fully backed by collateral and settle within predefined ranges using trusted data sources, avoiding risky features like use or liquidations. Quoted and settled in USDC, these contracts run through HyperCore, Hyperliquid’s engine for order execution, margin, and settlement on its blockchain. The permissionless deployment marks a step beyond the earlier HIP-4 markets on mainnet, which were controlled by validators, and echoes the earlier HIP-3 model that opened perpetual futures markets to independent developers.

By enabling anyone to launch outcome markets using the provided templates, Hyperliquid aims to broaden its market offerings and developer engagement. While still in its early days, the testnet environment lets builders fine-tune market parameters and understand settlement mechanics without risking real funds. No mainnet release date has been shared yet.

Hyperliquid’s current market activity remains modest compared to established players like Polymarket and Kalshi, with around $182,000 in open interest and just under $900,000 in notional volume reported recently. Sports markets drove much of the volume, although activity dipped after the FIFA World Cup concluded in July. Future growth will depend heavily on how many developers jump in and the variety of templates introduced.

Previous experiences with HIP-3 markets have underlined the critical need for accurate price feeds after a notable incident in July saw a perpetual contract on SK Hynix drop nearly 19% on a single trade. Such episodes highlight the challenges Hyperliquid faces as it expands its framework.
