What is Engine?

Engine is an AI agent that trades on your behalf on Hyperliquid, around the clock, by following a strategy you write or pick from the marketplace. Every decision is shown to you in plain English, and you can pause it whenever you want.

That's the whole product. The rest of this page is what each part of that sentence means.

Trades for you

You deposit USDC into your own Hyperliquid vault. Engine never holds it. The agent gets permission to place trades from that vault, and nothing else. Withdraw any time. Revoke the agent's authority with one click. We've put real thought into making this the kind of product you can walk away from cleanly. See Your funds, your control.

On Hyperliquid

Hyperliquid is where Engine trades. A high-performance perpetual futures exchange with the depth and uptime an agent actually needs to run 24/7. You'll need a wallet and USDC. That's it.

By rules you write or pick

Engine doesn't trade by a hidden model. It trades according to your strategy: a plain-English file describing what you want to trade, when to sit out, and how much to risk. You can subscribe to one from the marketplace or write your own from scratch. The file is yours to read; if you wrote it, it's yours to edit and share.

With nothing hidden

This is the part most products in the space don't do. Every decision the agent makes (what it read, what rule it matched, why it sized the way it did) streams to a live log you can scroll through and ask questions of. If a trade surprises you, ask the agent why. It'll tell you, with the numbers.
