Introduction

The sportsbook that’s actually a book.

Purrbook is a sportsbook interface built on Hyperliquid’s outcome markets. Unlike a traditional sportsbook, there’s no house setting lines against you — every bet is a trade on a real order book with real depth, and you can see exactly what you’re getting before you sign.

Why it’s different

• No house, no house edge. You trade against other participants on an order book. The price is set by real buyers and sellers, not by a bookmaker’s margin.
• Non-custodial. Purrbook never holds your money and never sees your private keys. Your browser signs every order and submits it directly to Hyperliquid.
• Cash out anytime. Selling your position back into the book is a normal trade at the current market price.
• Every market shows its judge. The resolution source is named on every market before you bet.

What can I bet on?

Whatever outcome markets are live on Hyperliquid — currently soccer (World Cup, Premier League) plus some crypto and macro markets. The catalog in the app always shows what’s actually tradable right now.
