What happens to your account when site data is cleared or the app is reinstalled

Lost Device or Cleared Storage

Your Hyperliquid agent key is stored locally — in browser storage on web, or in device storage on mobile. If that storage is cleared, the key is gone from the device. This is expected behavior, not a bug.

Your funds and positions are completely safe. The agent key is scoped to trading only — it cannot withdraw or transfer funds. Your actual account, balances, and open positions all live on Hyperliquid's chain and are unaffected.

What triggers this

Clearing browser site data or cache
Reinstalling the mobile app
Switching to a new device or browser profile
Using a private/incognito window (key isn't persisted across sessions)

How to recover

Go through the enable-trading flow again. You'll need to sign one signature to authorize a new agent key on the current device. The rest of the flow (unified mode, referral, builder fee) is already done — only the agent key step will appear.

This typically takes under 30 seconds.

If you're near the 4-wallet limit

Each re-authorization creates a new API wallet on your HL account. If you've done this many times across devices, you may be approaching the 4-wallet cap. See Managing API Wallets to review and revoke old keys before re-authorizing.
