Purrdict is a product and engineering team focused on HIP-4 prediction markets. The public landing site explains the protocol and products, while app.purrdict.xyz is the trading interface. We also publish open-source TypeScript tools and React components for teams building their own HIP-4 applications.
What Purrdict is
Purrdict turns HIP-4 outcome contracts into a complete product surface: live market discovery, order entry, portfolio views, recurring and multi-outcome market support, a permissionless testnet launch flow, and developer infrastructure.
The name is intentionally spelled Purrdict. It is the product brand—not a typo for “predict.” Our canonical public domains are www.purrdict.xyz for product information and app.purrdict.xyz for the application.
What we build
Our relationship to Hyperliquid and HIP-4
Purrdict builds on public Hyperliquid infrastructure and the observed HIP-4 protocol. It is not Hyperliquid's official prediction-market application, is not operated by Hyperliquid Labs, and does not speak for Hyperliquid.
Mainnet HIP-4 outcome markets are protocol-native markets on HyperCore. Purrdict's parlay and vault experiments are separate synthetic systems on HyperEVM Testnet; they should not be described as native HIP-4 order books.
Open-source work you can inspect
The Purrdict GitHub organization publishes the HIP-4 SDK and UI repositories. The @purrdict/hip4 package provides TypeScript utilities for market discovery, outcome mapping, price ticks, and order payloads. The component registry at ui.purrdict.xyz provides shadcn-compatible React building blocks.
We also publish a reproducible HIP-4 market dataset and hip4.fun, a distinct protocol reference and live archive. Both disclose the Purrdict publisher and neither presents Purrdict as the protocol owner.
Product status changes quickly. Network labels and current contract addresses shown in the live application or venue API take priority over old screenshots, posts, or third-party descriptions.
Official channels
Product updates are published through @hypurrdict on X. Code and releases live at github.com/purrdict. Community discussion happens in the official Purrdict Discord.
