Exos Architecture
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: a competitive layer of season standings, monthly ROI competitions, weekly promotion legions, and a recruiting ladder, scored on fees paid and skill, never on volume.

What Exos never does
- Hold, freeze, recover, or move your funds. It cannot.
- Execute anything server-side with your money. Orders sign on your device only.
- Score points on volume. Points accrue on fees actually paid.
- Fabricate urgency, counts, or numbers anywhere in the interface.
