This guide is for a DeFi-wallet user who already has USDC on Arbitrum. Email-login users can also receive supported assets at the address created for the email account, but they must confirm that address before transferring.
Before you deposit
You need all four items:
- The official Hyperliquid interface opened from a trusted bookmark.
- The exact account address you intend to fund.
- Supported USDC on Arbitrum, not USDT, bridged USDC on another chain, ETH, or ARB.
- A small amount of ETH on Arbitrum to pay the deposit transaction's network gas.
Network warning: “Arbitrum” in this guide means Arbitrum One as shown by the live Hyperliquid deposit flow. Match the token contract, network, wallet address, and live minimum before approving anything.
Step-by-step deposit
1. Confirm the active Hyperliquid address
Connect with the same email or wallet that will own the trading account. Copy the displayed public address and compare its first and last characters with the address in your wallet. Switching between email login and a DeFi wallet can open different accounts.

Open Hyperliquid →2. Check balances on Arbitrum
In the connected wallet, select Arbitrum and verify both:
- supported USDC is available;
- ETH is available for gas.
3. Open the native deposit flow
On the official trade page, click Deposit. Read the current asset, source network, minimum, destination account, and any fee message. Stop when the modal does not match this guide; the live product is authoritative.
4. Start with a controlled amount
Enter an amount above the live minimum while leaving enough ETH for gas. A small first deposit limits damage from a wrong account, unsupported token, or mistaken network.
5. Confirm in the wallet
Review the wallet request. The network must still be Arbitrum, and the amount must match. Never approve a request that asks for a seed phrase or private key. Submit the transaction and save its transaction hash without publishing your full account history.
Success check
The task is complete only when all three checks agree:
- the Arbitrum explorer shows a successful transaction;
- the connected Hyperliquid account shows the credited USDC balance;
- the displayed Hyperliquid address is the address you intended to fund.
When the balance does not arrive
Do not repeat the transfer immediately. Check, in order:
- Transaction missing or pending: verify the transaction hash and Arbitrum status. Wait for the network rather than submitting duplicates.
- Wrong account: compare the connected Hyperliquid address with the funded address.
- Wrong network or token: only the currently supported route can credit automatically.
- Below the minimum: Hyperliquid support currently documents a 5 USDC minimum for Arbitrum USDC deposits. Email-account recovery differs from external-wallet recovery.
- Successful supported transfer but no credit: preserve the hash, amount, time, network, token contract, and receiving address, then follow the official support decision tree.
What to do next
After the small balance is visible, calculate a deliberately limited position before ordering. Continue with Place Your First Hyperliquid Perp Trade Safely.
