Cryptocurrency trading has evolved into a sophisticated financial activity, requiring not just market insight but also advanced account management tools. Among leading global digital asset exchanges, OKX stands out for its robust infrastructure and user-centric features — one of the most powerful being the sub-account system. But what exactly is an OKX sub-account used for, and how can traders leverage it to improve their trading efficiency, security, and organization?
This guide dives deep into the functionality, benefits, and step-by-step operations of OKX sub-accounts, helping both beginners and experienced users make the most of this essential tool.
Understanding the OKX Sub-Account System
An OKX sub-account functions similarly to a supplementary card linked to a primary bank account. It allows users to create up to 300 sub-accounts under one main (parent) account. These sub-accounts operate independently in terms of login credentials and trading activities but remain under the control of the parent account holder.

Key Features of OKX Sub-Accounts
- Independent login access: Each sub-account has its own username and password, enhancing security and enabling team-based or multi-strategy management.
- No deposit/withdrawal rights: Sub-accounts cannot directly deposit or withdraw funds. All withdrawals must go through the parent account, ensuring centralized fund control.
- Supports multiple trading types: Sub-accounts can engage in spot trading, futures contracts, leveraged trades, and ETT (Exchange-Traded Tokens), making them ideal for diversified strategies.
- Inherits fee discounts: The user tier (and thus trading fee rate) is determined by the combined 30-day trading volume across all sub-accounts and the main account. All sub-accounts inherit the parent’s fee tier.
- Separate API rate limits: Each sub-account has independent API request quotas, allowing high-frequency traders or bots to scale operations without hitting rate caps.
These features make sub-accounts ideal for family portfolios, professional trading teams, fund managers, or individuals managing different investment strategies.
Why Use an OKX Sub-Account? 5 Core Benefits
1. Enhanced Fund Organization
By allocating specific assets to different sub-accounts, users can separate funds by strategy (e.g., long-term holding vs. active day trading), risk level, or purpose (personal vs. shared investments).
2. Improved Security
Since sub-accounts cannot initiate withdrawals, even if a sub-account credential is compromised, funds remain protected within the ecosystem. Transfers to external wallets must be approved via the parent account.
3. Team Collaboration Without Risk
Trading groups or investment partners can be given access to a sub-account with predefined permissions — allowing them to trade while keeping custody of funds centralized.
4. Optimized Fee Structures
All trading volumes from sub-accounts contribute to the parent’s tier calculation. This means frequent trading across multiple accounts can help reach VIP levels faster, reducing overall fees.
5. Better Tracking and Performance Analysis
With isolated balances and transaction histories, it’s easier to evaluate the performance of each strategy or team member independently.
How to Create and Manage an OKX Sub-Account
Creating a sub-account on OKX is straightforward:
- Log in to your OKX main account.
- Navigate to "Assets" > "Sub-Account Management".
- Click "Create Sub-Account" and set a unique username and password.
- Assign permissions (e.g., enable spot trading, disable API access).
- Transfer funds from the main account to the new sub-account using the internal transfer function.
Once created, the sub-account can begin trading immediately — with full access to supported markets and tools.
How to Transfer Funds Between Sub-Account and Main Account
Fund movement between accounts is secure and simple:
✅ Transferring from Main to Sub-Account:
Use the POST /api/account/v3/transfer API endpoint or the web interface:
- Go to Assets > Transfer
- Select source (main account) and destination (sub-account)
- Choose asset type and amount
- Confirm transfer
Funds arrive instantly and can be used for trading.
❌ Transferring from Sub-Account to Main Account:
Only possible from the sub-account’s funding wallet to the main account’s funding wallet.
- In the sub-account, go to Assets > Internal Transfer
- Move funds from trading wallet to funding wallet (if needed)
- Initiate transfer to main account
After funds reach the main account, standard withdrawal procedures apply.
You can monitor balances using:
GET /api/account/v3/sub-account — retrieves balance details including available, frozen, and total amounts across all sub-accounts.Frequently Asked Questions (FAQ)
