Overview
To address the pain points of fund segregation in the Classic Account, the Unified Account builds a one-stop fund management system. It breaks account barriers by managing assets of spot, cross margin trading, USDT-M Perp, and options under a single account, enabling cross-product margin sharing and eliminating the need for frequent transfers. It also expands eligible margin sources; in addition to base assets, unrealized PnL and Simple Earn flexible-term subscriptions can be used as margin for opening positions, significantly improving capital efficiency.
Through the "PnL offsetting" mechanism, where profits and losses from different products can offset each other, Unified Account reduces the overall risk. Liquidation within the account is determined by whether the total assets have met the maintenance margin requirement, instead of the PnL of a single asset. Even if some assets are temporarily at a loss, as long as the total assets meet the requirement, liquidation will not be triggered, further enhancing trading security.

Differences in Account Display
- Before upgrading to the Unified Account, the Assets page displays an upgrade guide. Spot, futures, and isolated margin trading accounts are displayed as separate and independent accounts.
After upgrading, in the Classic Spot Mode, the original Spot Account is renamed Unified Account. Only the name changes; the account scope still includes spot assets only. USDT-M Perpetual, BTC-M Perpetual, Delivery, and Options in the Futures Account are not included in the Unified Account and require manual transfers.
- After upgrading to the Single-Currency Margin Mode, Multi-Currency Margin Mode, or Portfolio Margin Mode, the Unified Account asset page displays key indicators such as Initial Margin Ratio (IMR), Maintenance Margin Ratio (MMR), and margin balance. The account scope now includes spot assets and USDT-M Perpetual and Options assets from the Futures Account. Correspondingly, USDT-M Perpetual and Options assets will not be displayed in the Futures Account.

Differences in Trading Page Display
- Before upgrading to the Unified Account, the account section on the trading page shows an entry to upgrade. Spot, futures, and options each have separate account panels showing independent balances and assets.
- After upgrading to the Classic Spot Mode, the trading page shows the current Unified Account mode. Users can switch modes, and account panels display the same information as before upgrading, with information of different trading types shown independently.
- After upgrading to the Single-Currency Margin Mode, Multi-Currency Margin Mode, or Portfolio Margin Mode, the trading page displays the current Unified Account mode. Users can switch modes, and the panel prioritizes displaying Unified Account-level information such as IMR and MMR, along with selected field information for certain trading types.
