How to Connect Rabby Wallet to Hyperliquid (Step-by-Step Guide)

Rabby

Why DeFi Power Users Choose Rabby for Hyperliquid

Rabby Wallet has earned a reputation as the wallet of choice for experienced DeFi traders, and for good reason. Built by the DeBank team, Rabby was designed from the ground up to solve the pain points that MetaMask users have complained about for years — clunky chain switching, blind transaction signing, and a lack of portfolio visibility.

For Hyperliquid traders specifically, Rabby brings three standout advantages. First, it auto-detects the correct chain when you interact with any dApp, so you never see a "wrong network" error. Second, its pre-transaction simulation shows you exactly what each transaction will do before you sign it, protecting you from phishing attacks and accidental approvals. Third, Rabby's built-in portfolio tracker lets you monitor your holdings across every chain without leaving the wallet.

Hyperliquid is a non-custodial exchange. Your wallet is your account — there are no emails, passwords, or KYC verification steps. Connect Rabby and you are ready to trade.

Prerequisites

Before connecting Rabby Wallet to Hyperliquid, make sure you have:

• Rabby Wallet browser extension installed (available for Chrome, Brave, Edge, and Opera)
• A funded wallet with USDC on the Arbitrum network (for depositing into Hyperliquid)
• A small amount of ETH on Arbitrum (under $1 worth, for the one-time bridge gas fee)
• A supported browser — Chrome, Brave, or Edge are recommended

If you do not have Rabby yet, the next section walks you through installing it from scratch.

Step-by-Step: Connect Rabby Wallet to Hyperliquid

1Install Rabby Wallet

If you already have Rabby installed, skip to Step 3.

1. Go to rabby.io
2. Click "Download" and select the browser extension for your browser
3. Click "Add to Browser" and confirm the installation
4. Rabby will open a welcome page — click "Get Started"
5. Choose either "Create New Address" or "Import Existing" (if you have a seed phrase from another wallet)
6. If creating new: write your 12-word seed phrase on paper and store it offline. This phrase controls your entire wallet.
7. Set a strong unlock password

2Configure Rabby as Your Default Wallet

If you have other wallet extensions installed (like MetaMask), Rabby may need to be set as the default provider:

1. Click the Rabby icon in your browser toolbar
2. Go to Settings (gear icon)
3. Find the "Default Wallet" toggle and make sure Rabby is selected
4. If you want Rabby to work alongside MetaMask, enable "MetaMask-compatible mode" so dApps that only detect MetaMask will also see Rabby

3Connect to Hyperliquid

1. Open your browser and navigate to app.hyperliquid.xyz
2. Click the "Connect" button in the top-right corner
3. Select "Rabby Wallet" from the wallet list (or "MetaMask" if Rabby is running in compatible mode)
4. Rabby will display a connection request showing the site URL and requested permissions — review and click "Connect"
5. You may be asked to sign a message verifying wallet ownership — click "Sign"

Rabby will automatically detect that Hyperliquid uses the Arbitrum network and switch to it. No manual chain configuration is needed.

4Apply a Referral Code (Critical — First Connection Only)

When you connect a new wallet to Hyperliquid for the first time, this is your only chance to apply a referral code. Our referral code (Concept211) gives you a 4% discount on all trading fees for the lifetime of your account, up to your first $25 million in volume.

If you connected through our referral link, the code is applied automatically. If you navigated directly to app.hyperliquid.xyz, check the referral section in your account settings to verify a code is active.

5Deposit USDC

With Rabby connected, deposit funds to start trading:

1. Click the "Deposit" button on Hyperliquid
2. Enter the amount of USDC you want to deposit
3. Rabby will display a transaction simulation showing you exactly what will happen — review it and click "Confirm"
4. Wait approximately 1-2 minutes for the deposit to confirm on-chain

Why Rabby's Security Features Matter for Trading

Rabby is not just another MetaMask clone. Its security architecture was built specifically for DeFi users who interact with smart contracts regularly — exactly the kind of activity you do when trading on Hyperliquid.

Pre-Transaction Simulation

Every time you sign a transaction through Rabby, it simulates the outcome first. You see a clear breakdown of what tokens leave your wallet, what tokens arrive, and what contracts are involved. If Rabby detects that a contract is flagged as malicious or if the transaction would drain your wallet, it warns you before you sign.

This is especially valuable when interacting with any DeFi protocol, including Hyperliquid's deposit bridge.

Approval Management

Rabby tracks every token approval you have granted to smart contracts. You can review and revoke approvals directly from the wallet interface, reducing the risk of old or forgotten approvals being exploited.

Phishing Protection

Rabby maintains a database of known phishing sites. If you accidentally visit a fake Hyperliquid domain, Rabby will block the connection attempt and display a warning.

Troubleshooting Common Connection Issues

Rabby Is Not Appearing as a Wallet Option

• Check that Rabby is installed and unlocked — Click the Rabby icon in your browser toolbar and make sure it is active
• Set Rabby as default wallet — Go to Rabby Settings and toggle "Default Wallet" on
• Disable conflicting extensions — If MetaMask or another wallet is installed, it may be intercepting the connection. Temporarily disable other wallet extensions
• Try MetaMask-compatible mode — If Hyperliquid only shows "MetaMask," enable Rabby's MetaMask-compatible mode in settings

Connection Succeeds But Immediately Disconnects

This can happen when browser privacy settings or extensions block persistent connections:

• Disable any ad blockers or privacy extensions for app.hyperliquid.xyz
• Make sure cookies are enabled for the site
• Try connecting in a regular browser window (not incognito)

Transaction Simulation Shows an Error

If Rabby's pre-transaction simulation fails or shows unexpected results:

• Make sure you have enough ETH on Arbitrum for gas fees
• Check that you are interacting with the real Hyperliquid domain (app.hyperliquid.xyz)
• Try refreshing the page and initiating the transaction again
• If the simulation shows a risk warning, do not proceed — verify you are on the correct site

Rabby Shows a Different Chain Than Expected

Rabby auto-detects chains, but occasionally it may default to the wrong one:

1. Click the chain indicator in Rabby
2. Manually select Arbitrum One
3. Refresh the Hyperliquid page and reconnect
