Terms & Legal

The interface vs. the protocol

Purrbook is a non-custodial interfaceto Hyperliquid’s outcome markets. Trades happen on the Hyperliquid protocol; Purrbook does not take custody of funds, execute trades on your behalf, or guarantee outcomes. Deposits, withdrawals, and settlement are functions of Hyperliquid, not of Purrbook.

Eligibility

Purrbook is for adults only — 18+ or 21+ depending on your jurisdiction. It is your responsibility to know and follow the laws that apply to you. Do not use Purrbook where doing so would be unlawful. Never bet money you can’t afford to lose.

No warranty; your responsibility

The interface is provided “as is,” without warranty. Odds are prices, not promises. You are responsible for the transactions you sign and for securing your own wallet, keys, and session key. Purrbook does not provide financial advice.
