How to Create and Use Sub-accounts on a Crypto Exchange?

Understanding Sub-account Functionality

1. Sub-accounts are distinct wallet identities created under a single master account on a cryptocurrency exchange platform.

2. Each sub-account maintains its own balance, transaction history, and API key permissions, independent of other sub-accounts.

3. They share the same KYC verification status as the parent account but operate with separate login credentials or access tokens.

4. Exchanges like Binance, Bybit, and OKX support sub-accounts for institutional users, trading teams, and portfolio managers.

5. Sub-accounts cannot initiate withdrawals to external addresses unless explicitly enabled and whitelisted by the master account holder.

Step-by-step Sub-account Creation Process

1. Log into the main exchange account using two-factor authentication and navigate to the “User Center” or “Account Management” section.

2. Locate the “Sub-account Management” tab—this may be nested under “Security Settings” or “Institutional Services” depending on the platform.

3. Click “Create Sub-account”, enter a unique username, select permission levels (e.g., spot trading only, no margin access), and confirm via email or TOTP.

4. The system generates a dedicated sub-account ID and displays it immediately; some platforms require manual activation before use.

5. Assign deposit addresses for each supported blockchain—these differ from the master account’s addresses and are auto-generated per sub-account.

Assigning Roles and Permissions

1. Role templates such as “Viewer”, “Trader”, and “Fund Manager” define what actions a sub-account can perform.

2. A Viewer sub-account sees balances and order history but cannot place trades or transfer assets internally.

3. A Trader sub-account executes orders across specified markets but lacks withdrawal or API key creation rights.

4. A Fund Manager sub-account handles internal transfers between sub-accounts and initiates approved off-platform withdrawals.

5. Permission changes require re-authentication and may trigger email/SMS notifications to the master account owner.

Managing Internal Transfers Between Sub-accounts

1. Internal transfers occur instantly and without network fees since they are ledger adjustments within the exchange’s database.

2. Initiate a transfer by selecting the source and destination sub-account IDs, entering the asset symbol and amount, then confirming with 2FA.

3. Transfers are logged in both sender and receiver histories with timestamps and reference IDs visible in the audit trail.

4. Some exchanges impose daily limits on cross-sub-account transfers unless elevated permissions are granted through support ticket escalation.

5. Internal transfers do not appear on public block explorers and are invisible to third-party analytics tools.

Frequently Asked Questions

Q: Can a sub-account generate its own API keys?A: Yes—if permitted during creation or later modified by the master account, sub-accounts can create isolated API keys with scoped permissions.

Q: Are sub-account balances included in the master account’s total equity calculation?A: Yes—exchanges aggregate all sub-account balances when computing margin ratios, VIP tiers, and fee discounts for the parent account.

Q: What happens to sub-accounts if the master account is locked or suspended?A: All associated sub-accounts become inaccessible until the master account is restored; no independent recovery path exists.

Q: Do sub-accounts support staking or yield products?A: Support varies—some platforms allow staking only from the master account, while others enable per-sub-account participation in flexible savings or locked-term programs.
