Perps sub-accounts let you "split perps collateral into isolated accounts, switch the active trading account, and move USDC between accounts." Because N1 uses cross margin within an account, sub-accounts are the way to keep a strategy's risk from touching the rest of your collateral.
Where to find them
Open Settings → Perps accounts. Your original account is labelled Master, the account you are trading is labelled Active, and the header shows how many you have used — for example 3/8 accounts used.
Sub-accounts are available in N1 Mode only.
Creating a sub-account
- Select Create.
- Choose the account to fund it from under Funded by — the panel shows that account's Available Balance.
- Enter the USDC amount to seed it with.
- Select Create and fund sub-account.
You can hold up to 8 perps accounts in total. Beyond that, creation is blocked with "Current limit reached. Only 8 accounts allowed." If the seed amount is larger than the funding account's balance you see "Amount exceeds available balance."
Switching accounts
Select Set active on the account you want to trade. Positions, orders, balances and health are per account, so the trading interface reflects only the active one.
Moving USDC between accounts
- Select Transfer.
- Pick the From and To accounts and enter an amount.
- Confirm — the app reports "USDC transferred between perps accounts."
Transfers between your own perps accounts are internal, so there is no on-chain withdrawal step. If you only have one account you will see a prompt to "Add another sub-account in Settings → Perps accounts to move USDC between your perps accounts."
Withdrawals go through the master account
"All withdrawals are handled by the master account. Transfer funds to the master account to withdraw fully. Withdrawals cannot be sent directly from sub-accounts."
So to withdraw funds sitting in a sub-account: Transfer them to the master account first, then withdraw from there. See Withdrawals.
Risk
Each account has its own margin and its own liquidation exposure — a liquidation in one sub-account cannot pull collateral from another. That isolation is the point, but it also means a sub-account can be liquidated while your other accounts still hold plenty of USDC. Monitor health on the account that holds the position, not just your overall balance.
