# Connecting a wallet

## Connecting

Hit connect and pick a wallet: a browser extension (MetaMask, Rabby, and similar), a mobile
wallet over WalletConnect, or an email login if this DEX has one enabled. There's no separate
account to create, your wallet address is your account, and if you've traded on Hyperliquid
before with that address, your balance, positions and history are already there.

## One-time setup

The first time you connect, you'll sign two things:

1. **A trading key approval.** This creates a key held by your browser that signs your orders
   locally, so you get one wallet popup up front instead of one per order. It's scoped to this
   site and disposable, revoke or replace it any time from the setup step without touching keys
   you've approved elsewhere on Hyperliquid.
2. **A builder fee approval.** This sets the maximum fee rate this DEX can charge you per fill.

Both need your wallet to have deposited to Hyperliquid at least once. A brand-new wallet with no
deposit will fail this step, fund the account first. See [Fees](/trading/fees) for what the
builder fee approval covers.

## Staying signed in

By default the trading key lives in memory for the tab and is gone on reload. Two settings change
that:

- **Persist Trading Connection** keeps it in your browser's local storage so a reload doesn't ask
  you to re-approve.
- **Biometric unlock** (where your device and browser support it) encrypts the key at rest behind
  Face ID, Touch ID or fingerprint. Restoring a session then takes one biometric prompt instead of
  a wallet round-trip, and the key is never stored in plain text.

Neither setting extends what the key can do. Its authority is still whatever you approved on
Hyperliquid, and you can revoke it there at any time.
