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.
