All new Margin Special Key users. The agreement is signed at the master account level and binds all of your Binance accounts and sub-accounts. Once signed:
Yes. Signing at the master level authorizes Margin Special Key creation across all sub-accounts and brings all Cross Margin Classic and Portfolio Margin Pro sub-accounts with active Margin Special Keys under the LiquidationLoan framework.
You can create up to 30 API keys per Binance account, including both normal and special keys.
The Margin Special API Key is only applicable with “/api” endpoints. It is strongly recommended not to use this key for “/sapi” endpoints.
You can only use the Margin Special API Key to place orders. For margin borrowings, please utilize the standard API key.
If a forced liquidation on an account with a Margin Special Key results in a net deficit, the deficit is handled according to the account type (see Q11 below).
The outcome depends on whether a Margin Special Key has been created on the account:
| Account Type | Margin Special Key Status | Will a LiquidationLoan be created if the margin account is in deficit? | Logic |
| Cross Margin Classic |
AND
| Yes | If a net deficit remains after liquidation, the deficit is represented by a LiquidationLoan on the user’s account. The user is responsible for repayment of the deficit in full. |
| Cross Margin Classic |
OR
| No | Standard liquidation logic for Cross Margin Classic mode applies.
|
| Portfolio Margin Pro Account | - | Yes | Follows existing Portfolio Margin Pro Account logic (for more details, please refer to this article). |
| Isolated Margin | - | No | Standard liquidation logic for Isolated Margin mode applies. |
There are two steps:
⚠️ Deleting the key alone is not enough. Until the exit API call is completed and confirmed, your associated margin accounts remain bound by the Supplemental Product Terms and the LiquidationLoan policy.
No — deleting the key alone does not discharge your obligations. You remain subject to the Supplemental Product Terms until you complete the full exit via the dedicated "Exit Margin Special Key" API and receive confirmation from Binance.
Your Margin Special API Key may stay active despite periods of inactivity; however, Binance reserves the right, in its sole and absolute discretion, to revoke access at any time if the key is deemed by Binance, to be inactive. Please watch for email notifications regarding any such updates.
