Guardian, the 24/7 liquidation shield

When it acts

Guardian measures each position's distance to liquidation: equity minus maintenance margin, as a share of equity. At 100% the position is far from danger. At 0% Hyperliquid liquidates it.

When that distance drops below your buffer, 15% by default, Guardian moves USDC from your idle balance into the position until the distance is back to 50%. You choose the buffer, and you can cap how much of your idle balance Guardian may use.

How it moves money

• For an isolated position, it adds margin to that position directly.
• For cross positions, it moves USDC from your spot balance into your perp balance, where it backs every cross position.
• If the idle balance is in the hedged funding trade, it unwinds just enough of the hedge to free the USDC it needs.

Every one of these is an action Hyperliquid allows an agent key to sign. None of them can send funds out of your account.

Its own key, per user

When you turn Guardian on, your wallet approves a dedicated agent key for it. The key is encrypted at rest and only the isolated keeper service can use it. Hyperliquid lets an agent key live for at most 180 days, so Guardian asks you to re-approve twice a year. The app shows a countdown, and we remind you by email and in the app 14 days before it expires.

What it cannot do

• It cannot withdraw, transfer funds to another address, or approve new keys.
• It cannot save a position if your idle balance or your cap runs out.
• It cannot act faster than Hyperliquid accepts orders. In a gap move, price can pass the liquidation level before any keeper reacts.

Every action is on the record

Each top-up is written to your activity log with the time, position, amount and the distance before and after. The same action is published, without your address, on the public engine ledger.

Holders and everyone else
