How to connect Rabby Wallet to Hyperliquid

Verified against Hyperliquid docs: How to start trading and Hyperliquid docs: Referrals · by Hyperliquid Academy

Rabby is an EVM wallet like any other, and the connection flow below is the same one MetaMask uses. Two differences are worth the switch.

It switches networks for you. A site that expects Arbitrum gets Arbitrum, without you noticing you were on Ethereum. The wrong-network mistake is the most expensive routine error in crypto, and this removes most of it.

It tells you what a signature will do. Before you approve, Rabby simulates the request and shows the effect: which assets move, which permissions are granted, whether the contract is known. MetaMask shows you a block of hex and asks you to trust it.

That second point matters more here than on most sites. Hundreds of lookalike domains exist for Hyperliquid specifically. A phishing clone can imitate the interface perfectly, but it cannot make a draining signature look harmless in a wallet that simulates it first.

The step that expires

A referral code only attaches to a wallet that has never traded. After your first fill, the 4% fee discount is gone on that address for good. Do it before anything else, whichever wallet you use.

Step by step

  1. Install Rabby and back up the recovery phrase

    Install from your browser’s own extension store. Write the recovery phrase on paper before funding anything: anyone holding it holds your money, and no one can reverse that.

    If you already use MetaMask, you can import the same phrase and keep the same address, which means the same Hyperliquid account.

    You should see the Rabby extension with an account, and the phrase written on paper

  2. Open the app through a referral link

    The link applies the code automatically. You can also enter it manually on the referrals screen. Either way, before your first order.

    You should see the referrals screen showing a code attached to your address, before any trade

  3. Click Connect, then click MetaMask

    Rabby is not listed by name in the chooser, and that trips people up. It takes over the browser’s injected-wallet slot, which is the slot MetaMask normally occupies, so clicking MetaMask opens Rabby.

    If both are installed and the wrong one opens, disable the other extension or set Rabby’s priority in its own settings.

    You should see Rabby opening rather than MetaMask, and your address in the top-right corner

  4. Accept the terms, and sign that too

    An easy step to be surprised by: accepting the Terms of Use and cookie policy is recorded as a signed message, not just a click. It costs no gas. Check the request comes from app.hyperliquid.xyz before you confirm.

    You should see two ticked checkboxes, then a signature request of type Hyperliquid:AcceptTerms

  5. Click Establish Connection and read the preview before signing

    This is where Rabby earns its place. The signature is gas-free and authorises order placement through an agent key; it cannot withdraw funds. Rabby’s preview should say as much. If it shows a token approval or a transfer instead, stop and check the domain.

    You should see the order ticket becoming active

  6. Deposit USDC

    Send USDC on Arbitrum, Ethereum, Base or Polygon. Rabby will offer to switch to the right chain rather than letting you send on the wrong one. Keep a little of that chain’s gas token; the trade itself costs no gas. The deposit guide covers every route.

    You should see a USDC balance on your Perps account within a few minutes

What it costs once you are trading

Cost of a $10,000 taker order as each discount is added

  • Base rate, no discounts $4.50 0.045% Tier 0, nothing staked
  • With referral code $4.32 0.0432% 4% off, applies from trade one
  • Referral + Silver staking $3.67 0.03672% Over 1K HYPE staked and linked
  • Referral + Diamond staking $2.59 0.02592% Over 500K HYPE staked and linked
  • Everything, at the top volume tier $1.38 0.01382% Over $7B of 14-day volume as well

Your wallet has no effect on your fees. At the entry tier a taker order costs 0.045% of notional, or 0.0432% with a code applied. What does change your cost is trading as a maker instead of a taker, which is worth more than every other lever combined.

Troubleshooting

MetaMask opens instead of Rabby. Both are competing for the same injected slot. Disable the one you are not using, or set Rabby’s priority in its own settings. There is no “Rabby” button to click instead.

Connected, but the site still shows disconnected. Remove the site from Rabby’s connected list, refresh, connect again.

The signature preview shows something unexpected. That is the feature working. Do not approve. Check the domain character by character against your bookmark.

Deposit sent, nothing arrived. Check the source chain explorer, then check whether it landed in Spot rather than Perps. Transferring between those two balances is free and instant.

Where to go next

If you are still deciding, our wallet comparison covers every option including email login, which needs no wallet at all. If you already use MetaMask and would rather not switch, the MetaMask guide is the same flow.

Once you are connected, the ten-minute walkthrough takes you to a first position with a stop attached.

Frequently asked questions

Is Rabby better than MetaMask for Hyperliquid?

For most people yes, for two specific reasons: it switches chains automatically instead of leaving you on the wrong one, and it previews the effect of a signature before you approve it. Once connected, both behave identically and neither changes your fees.

Does Rabby support Arbitrum?

Yes, along with the other chains Hyperliquid accepts USDC from. Rabby detects which network a site expects and offers to switch, so the wrong-network deposit mistake is much harder to make.

Can I import my MetaMask wallet into Rabby?

Yes, with the same recovery phrase or private key, and you keep the same address. Because your Hyperliquid account is the address, your positions, balances and fee tier are unchanged.

Does Rabby work with a hardware wallet?

Yes. Ledger, Trezor and others pair through Rabby, and its signature preview is arguably more useful there, because a hardware screen shows you less.

Is Rabby safe to install?

It is open source and widely used. Install it from your browser's own extension store and never from a link someone sent you, which is the same rule that applies to every wallet.
