# Sub-accounts

Up to 10 sub-accounts can be created after reaching $100,000 in volume. Every additional $100M in volume enables the ability to create 1 additional sub-account, up to a maximum of 50 sub-accounts.&#x20;

Sub-accounts share the same fee tiers as the master account, but referral discounts do not apply to sub-accounts.&#x20;

The number of API wallets available starts at 3 for all master accounts and increases by 2 per sub-account. Refer to the [API Docs](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/api/exchange-endpoint#subaccounts-and-vaults) for trading via sub-account.&#x20;
