Managing multiple accounts on a cryptocurrency exchange can significantly enhance your trading flexibility, especially when organizing funds across different strategies or team members. OKX, one of the leading digital asset platforms, offers a powerful sub-account feature that allows users to create separate trading identities under a single main account. This guide will walk you through how to buy crypto using an OKX sub-account, how to set it up, transfer funds, and make the most of this advanced functionality.
Whether you're a solo trader managing different portfolios or part of a team delegating access, understanding the OKX sub-account system is key to efficient and secure crypto trading.
What Is an OKX Sub-Account?
An OKX sub-account is a secondary account linked to your primary (main) account. It operates under the same user ecosystem but allows for independent management of assets and trading activities. Sub-accounts support various functions including:
- Spot trading
- Margin trading (spot leverage)
- Futures and contracts
- Internal fund transfers
However, sub-accounts cannot directly purchase crypto with fiat—they rely on fund transfers from the main account or internal deposits. Once funds are transferred, they can be used freely for trading.
This structure enhances security and control, especially useful for teams, family members, or traders segmenting their investment strategies.
How to Buy Crypto Using an OKX Sub-Account
Since sub-accounts don’t support direct fiat purchases, the process involves two steps: transferring funds from the main account and then executing trades within the sub-account. Here’s how:
Step 1: Log In to Your Main OKX Account
Open the OKX app or visit the official website and log in with your credentials. Navigate to:
👉 Discover powerful trading tools and manage sub-accounts seamlessly on OKX.
Assets → Fund Transfer
This section allows internal transfers between your main account and any linked sub-accounts.
Step 2: Switch to Sub-Account Transfer Mode
Tap the "Convert" button in the top-right corner to switch to sub-account transfer mode. You’ll now see options to select:
- Transfer direction: From (source) and To (destination)
- Specific sub-account name
- Cryptocurrency type (e.g., USDT, BTC, ETH)
Step 3: Enter Transfer Amount
Input the amount you wish to transfer. Ensure sufficient balance in the source account. After confirming details, click Confirm to complete the transfer.
💡 Tip: You can reverse the transfer direction at any time to move funds back from a sub-account to the main account.
Step 4: Access Sub-Account & Trade
Once funds arrive in the sub-account:
- Switch to the sub-account interface (via profile/settings).
- Go to Trade → Spot or Contracts, depending on your strategy.
- Place buy orders just like on the main account.
Now, your sub-account is actively trading with allocated capital—ideal for testing strategies without risking your entire portfolio.
How to Create an OKX Sub-Account
Before transferring funds, you need to set up a sub-account. Follow these steps:
Step 1: Go to Sub-Account Settings
On the OKX website or app:
Profile (top-right) → Sub-Accounts → Create Sub-Account
Step 2: Fill in Account Details
Provide the following:
- Login name for the sub-account
- Password
- Account type: Choose based on intended use (e.g., trading, funding)
- Optional: Enable asset inheritance or initial funding settings
Click Submit when ready.
Step 3: Verify Identity
Enter:
- SMS verification code
- Google Authenticator code (if enabled)
Then confirm with OK.
✅ Your sub-account is now created.
📌 Note: Newly created sub-accounts inherit the main account’s fee tier starting from 00:00 UTC+8 the following day.
Fund Transfer Between Main and Sub-Accounts
After creation, transfer crypto from your main account:
- Return to Assets → Fund Transfer
Select:
- From: Main Account
- To: [Your Sub-Account Name]
- Choose coin and amount
- Confirm transfer
You can also move funds back or between multiple sub-accounts if needed.

Frequently Asked Questions (FAQ)
Q1: Can I buy crypto directly in an OKX sub-account?
No. Sub-accounts cannot directly purchase crypto with fiat (like USD or EUR). You must first buy crypto on the main account or deposit it externally, then transfer it to the sub-account.
Q2: How many sub-accounts can I create?
The number depends on your user level:
- Regular users: Up to 3 sub-accounts
- Higher-tier users (e.g., VIPs): More, based on account status
Check your limits under Sub-Account Management → Tier Permissions.
Q3: Do sub-accounts have separate wallets?
Sub-accounts share the same wallet infrastructure as the main account but operate with segregated balances. All transfers occur internally and are instantaneous.
Q4: Can a sub-account withdraw funds?
No. Only the main account can initiate external withdrawals. This adds a layer of security—sub-accounts can trade but not withdraw assets directly.
Q5: When does a sub-account get the main account’s fee rate?
Newly created sub-accounts inherit the main account’s fee tier at 00:00 UTC+8 on the next calendar day after creation.
Q6: Is there a fee for transferring between accounts?
No. Internal transfers between main and sub-accounts are completely free and processed instantly.
Best Practices for Managing Sub-Accounts
To maximize efficiency and safety:
- Use clear naming conventions (e.g., “Bot_Trading”, “Long_Term_Hold”)
- Regularly review transaction history and balances
- Restrict unnecessary permissions
- Never share main account credentials—even with trusted parties
