An overview of what EXOS is, and what it deliberately is not.
Hyperliquid is a performant blockchain offering permissionless access to hundreds of perpetual trading markets. Trades, execution, and settlement are handled on-chain and processed by Hyperliquid validators. EXOS does none of that work and never touches it.
EXOS is a non-custodial interface to Hyperliquid, built on the protocol's builder-code standard. Every order is signed on your own device by keys you control and executed by the protocol; EXOS attaches a builder fee to orders placed through this interface and the protocol collects it. EXOS is not an exchange, broker, custodian, or adviser, and it is not the exclusive means of accessing Hyperliquid markets: your account, positions, and funds are protocol-level and reachable through any interface at any time.
On top of the trading surface, EXOS runs the Battle Arena: half-hour duels in the Ludus, judged on return; a monthly Royale, seated by a draw of tickets earned from volume and bouts; and the season's crown, the Rudis. Season points come from the fees paid through EXOS.
