Set up a new Hyperliquid account for Coldfront
Add a new account on your cold wallet, open app.hyperliquid.xyz/join/COLDFRONT with it, deposit, authorize an API wallet on the API page, and store the API key in Coldfront. You need this only if your current account already uses another referral code.
Why a new account
Coldfront is free because accounts join with code COLDFRONT. An account keeps the first referral code it uses and cannot change it. If yours already has another code, add a second account on the same cold wallet. A separate trading account is also good practice: it keeps your trading funds apart from the rest of your holdings.
Step 1: Add an account on your cold wallet
Most cold wallets can hold several accounts. Add a new one and use it only for Hyperliquid trading.
Step 2: Join with the code
Open app.hyperliquid.xyz/join/COLDFRONT and connect the new account.
Step 3: Deposit
Deposit USDC; Hyperliquid creates the account on the first deposit.
Step 4: Authorize an API wallet
On the API page: name, Generate, copy the API key, Authorize.
Step 5: Set up Coldfront
Paste the API key, choose a passphrase, disconnect the cold wallet, trade.
Moving funds from your old account
Withdraw from the old account to the new account's address, then deposit into Hyperliquid from the new account. Both are on the same device, so each step is a signature on it. Check the address carefully before you send.
Check the code
On Hyperliquid's Referrals page, press Enter Code. It should say "You are using the code: COLDFRONT". If it doesn't, open the join link again and press Join.
