Sub-accounts
A sub-account is a separate book under your main Hyperliquid account, with its own margin, positions and balances. Use them to isolate risk — run a strategy, a hedge, or a large size in its own account so a blow-up in one can’t touch the others.
Your main account signs everything — a sub-account has no key of its own. Switching to a sub only changes which book your orders execute on; the signature still comes from your main wallet (or its trading agent).
One trading agent covers your main account and all its sub-accounts — nothing to set up per sub.
Where to find them
Open Portfolio › Sub-accounts. You’ll see your main account plus every sub-account, each with its live equity and open positions. Expand a row for the Perps / Spot breakdown, the address, and per-account actions.
Creating a sub-account
Click New sub-account and give it a name. Hyperliquid gates creation by lifetime trading volume:
- 10 sub-accounts unlock after $100k of volume,
- +1 for every additional $100M, up to a maximum of 50.
If your account isn’t eligible yet, Hyperliquid tells you why.
Renaming
Expand a sub-account and choose Rename. The name is just a label to tell your books apart — it moves no funds.
Funding a sub-account
Sub-accounts are funded from your main account, not by an external deposit. Expand a sub, choose Transfer, and move USDC (or any spot token) between your main account and the sub — you pick the asset and the direction.
Transfers are signed by your main wallet (one signature). Moving funds is a wallet action, never an agent one.
Trading from a sub-account
Switch the active account from the account switcher — the dropdown on the wallet button in the navbar, or the header of the in-app wallet. A full-width banner stays at the top of the app while you’re acting as a sub, so you always know which book you’re trading.
While a sub-account is active:
- Positions, orders, balances and the value chart are the sub’s.
- Orders execute on the sub — your main account signs, and the action is tagged to run on the sub’s book.
- Deposits, withdrawals and sends stay on your main account — move funds to a sub via Transfer instead.
Reload the page and you’re back on your main account: the active-account choice is never persisted, so you can’t unknowingly trade a sub.
New sub-accounts are unified by default — spot and perps share one collateral pool — so USDC you send to a sub backs its perp trading directly, with no spot→perp move needed.
Hiding a sub-account
Have books you rarely touch? Click the eye icon on a sub in the panel to hide it — it greys out there and drops out of the account switcher. Unhide it the same way. Hiding is a per-device display preference; it moves nothing and changes nothing on Hyperliquid.
