Introduction

Own the move. Keep your keys.

Purrbook is a non-custodial interface built on Hyperliquid’s spot, perps, and outcome markets. No one sets the price against you — every position 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 built-in edge. You trade against other participants on an order book. The price is set by real buyers and sellers, not by a hidden 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 trade.

What markets are available?

Whatever spot, perps, and outcome markets are live on Hyperliquid. The catalog changes as markets list and settle — the app always shows what’s actually tradable right now.
