How to Bridge to Arbitrum and Deposit to Hyperliquid

To trade perpetuals on Hyperliquid, you first need to fund your account with USDC. Hyperliquid runs on its own L1, but its deposit flow currently connects mainly through Arbitrum One. In practice, that means you usually need to move funds to Arbitrum first, then deposit from Arbitrum into Hyperliquid.

This guide walks through the full workflow and explains how to use OneKey Wallet to verify each step and reduce signing risk.

Why Hyperliquid deposits go through Arbitrum

Hyperliquid states in its official docs that its current deposit bridge is deployed on Arbitrum One. Whether your USDC starts on Ethereum mainnet, Optimism, or another chain, the asset needs to arrive on Arbitrum before it can enter your Hyperliquid trading account through the deposit contract.

Typical route:

1. Move assets to Arbitrum One.
2. Make sure you have native USDC on Arbitrum.
3. Deposit USDC from Arbitrum into Hyperliquid.

Before you start

Check the following before bridging:

• Your wallet has the Arbitrum One network added. You can use Chainlist to add it safely instead of manually entering RPC details.
• You have some ETH on Ethereum mainnet for gas if you are bridging from mainnet.
• If you use a OneKey hardware wallet, make sure the firmware is up to date and OneKey Bridge is running.
• OneKey natively supports Arbitrum One. In the OneKey App, you can switch networks from the top network dropdown without manually configuring RPC settings.

A good habit: start with a small test amount, especially if this is your first time using a bridge or depositing to Hyperliquid.

Bridge to Arbitrum with the official Arbitrum Bridge

The official Arbitrum Bridge, bridge.arbitrum.io, is the most trusted route for moving funds from Ethereum mainnet to Arbitrum One.

Steps:

1. Open bridge.arbitrum.io and connect your wallet.
2. Select Ethereum mainnet in the “From” field and Arbitrum One in the “To” field.
3. Enter the amount of ETH or USDC you want to move.
4. Review the estimated gas fee.
5. Click “Move funds to Arbitrum One.”
6. Confirm the transaction in your wallet. If using OneKey hardware wallet, verify the transaction details on the device screen before signing.

The official bridge usually takes around 10 minutes. You can paste the transaction hash into Arbiscan to track progress.

If your funds are on Optimism, BSC, or another EVM chain, you may use a third-party bridge aggregator such as Stargate or Across Protocol. When using third-party bridges, always enter from the project’s official website and avoid search engine ads, which are a common phishing vector.

Confirm your assets on Arbitrum and convert to USDC if needed

After the bridge transaction completes:

1. Search your wallet address on Arbiscan.
2. Open the “Token Transfers” tab.
3. Confirm that your ETH or USDC has arrived on Arbitrum.

If you bridged ETH or another token, you need to swap it into USDC on Arbitrum, for example through Uniswap on Arbitrum.

Important: Hyperliquid accepts native USDC on Arbitrum, not USDC.e, the bridged version. Before swapping or depositing, make sure you select the correct USDC token. The native USDC contract address can be checked in Hyperliquid’s official documentation.

Deposit from Arbitrum to Hyperliquid

Once you have native USDC on Arbitrum:

1. Open the Hyperliquid App.
2. Connect your wallet. If using OneKey hardware wallet, verify the connection request on your device before approving.
3. Click “Deposit” in the top-right corner.
4. Enter the amount of USDC you want to deposit.
5. Approve USDC spending when prompted by your wallet.
6. Confirm the deposit transaction.

Funds usually appear in your Hyperliquid account balance within 1–3 minutes.

For your first deposit, use a small amount to confirm the workflow. After everything looks correct, you can decide whether to deposit more.

Common issues and how to fix them

Balance does not update after deposit
Wait about 5 minutes, then refresh the page. Hyperliquid L1 confirmation may take a few blocks.

You used USDC.e instead of native USDC
The deposit may fail or be returned. Swap into native USDC on Arbitrum and try again.

Not enough gas on Arbitrum
You need a small amount of ETH on Arbitrum to pay for the deposit contract interaction.

Wallet connection fails
Check wallet compatibility through WalletConnect documentation, or update OneKey App to the latest version.

Why use OneKey for this workflow

Bridging and perps deposits involve multiple approvals, contract calls, and network switches. OneKey helps by keeping private keys offline when used with a hardware wallet and requiring physical confirmation for sensitive actions.

For this Arbitrum-to-Hyperliquid workflow, OneKey is useful for:

• Switching directly to Arbitrum One in the app.
• Reviewing wallet connection and signing requests.
• Confirming bridge, approval, and deposit transactions on a hardware device.
• Keeping a consistent wallet setup for on-chain funding and OneKey Perps trading workflows.

After funding your account, you can also use OneKey Perps as a practical way to access perpetual trading from within the OneKey ecosystem, while keeping signing and account management tied to the same wallet setup.

Conclusion

Bridging to Arbitrum and depositing to Hyperliquid can feel complicated the first time, but the process is straightforward once you know the path: use a trusted bridge, confirm you have native USDC on Arbitrum, keep enough ETH for gas, and verify every signature carefully.

If you do not already use OneKey, you can download the app or choose a hardware wallet at onekey.so/download. Once set up, use OneKey Wallet and OneKey Perps as your practical workflow for managing funds, signing transactions, and trading perps with better operational security.

FAQ

Q1: Can I withdraw directly from a centralized exchange to Hyperliquid?

Some centralized exchanges support withdrawals to an Arbitrum address. In that case, choose the “Arbitrum One” network in the exchange withdrawal page and enter your own wallet address. Once the funds arrive in your wallet on Arbitrum, deposit them into Hyperliquid. This can skip the Ethereum mainnet bridge step.

Q2: How much gas does bridging cost?

Using the official bridge from Ethereum mainnet to Arbitrum requires Ethereum mainnet gas, which changes with network congestion and can range from a few dollars to tens of dollars. Depositing from Arbitrum to Hyperliquid is usually much cheaper, often under $0.10 in gas.

Q3: How long does it take for funds to arrive after bridging?

The official Arbitrum Bridge from Ethereum mainnet to Arbitrum usually takes about 10 minutes. Third-party bridge aggregators may be faster, often around 1–5 minutes, but you should evaluate their smart contract and bridge risks. Depositing from Arbitrum to Hyperliquid usually takes 1–3 minutes.

Q4: How do I switch to Arbitrum in OneKey Wallet?

In the OneKey App, open the network dropdown at the top and select “Arbitrum One.” If it does not appear, go to network management to add it manually, or use Chainlist for one-click setup.
