# Common Questions About Cross-Exchange Accounts ｜ Gate

1. What is a CrossEx Account?

The English name for 跨所账户 is CrossEx. It’s an all-in-one trading and settlement platform designed for professional investors, quantitative teams, and institutions to operate across multiple exchanges. Leveraging a unified account system, low-latency matching and execution, and a unified settlement model across exchanges, CrossEx enables users to connect to multiple major exchanges at minimal cost, share margin across exchanges, and significantly enhance trading execution quality and capital efficiency.

2. What business scope does the CrossEx account support?

• Supported trading types: Spot, cross-margin, and USDT-margined perpetual contracts.
• Maximum leverage: Up to 50x.
• Supported position modes: One-way and hedge (two-way) positions.
• Margin modes: Cross-margin and isolated margin (isolated margin supported only for Hyperliquid).
• Account margin modes: Cross-exchange margin and single-exchange margin. The former allows USDT, BNB, BTC, ETH, SOL, XRP, USDC, KRAKEN_USD, and HYPERLIQUID_USDC to be used as unified cross-exchange margin assets for centralized risk management and improved capital efficiency. The latter supports USDT and other assets for single-exchange margin, managed independently for risk control.

3. Which assets can be transferred in a CrossEx account?

Currently, the assets that can be transferred bi-directionally within the CrossEx account or between the unified account via the fund transfer API are: USDT, BTC, ETH, XRP, BNB, SOL, TRX, DOGE, ADA, SUI, AVAX, LTC, DOT. Please refer to the /api/v4/crossex/transfers/coin API for the most up-to-date information.
Special restrictions:

• CROSSEX_KRAKEN: Only USDT transfers are supported.
• CROSSEX_HYPERLIQUID: Only USDC transfers between SPOT and Hyperliquid accounts are supported.

4. What are the advantages of CrossEx?

• Unified access: No need to open accounts or develop integrations for multiple exchanges separately. Simply connect to the CrossEx API to trade across multiple exchanges simultaneously, greatly lowering the technical and operational barriers for cross-exchange trading.
• Improved capital efficiency: CrossEx provides cross-exchange margin and asset transfer capabilities. A single USDT balance can be shared across exchanges, with profits and losses offset across positions, significantly increasing capital utilization.
• Unified system: CrossEx features a unified trading, settlement, and independent risk control mechanism, shielding users from underlying differences between exchanges and enhancing the overall trading experience and risk controllability.
• Cost advantage: Offers competitive fee rates covering retail, broker, and institutional clients, helping you reduce trading costs.

5. How do you distinguish assets in a CrossEx account?

• When assets are located on different exchanges, the symbol will include the specific exchange identifier, such as BINANCE_FUTURE_ADA_USDT or OKX_FUTURE_ADA_USDT.
• When USDT is used as the unified cross-exchange margin, the symbol will not include an exchange identifier.

6. How do you trade on a CrossEx account?

CrossEx accounts support API trading only.
You can use the /api/v4/crossx/rule/symbols endpoint to query trading pair information. The returned symbol field indicates the corresponding exchange and market type (e.g., BINANCE_FUTURE_ADA_USDT or OKX_FUTURE_ADA_USDT). Only assets with matching symbols can be traded in the corresponding exchange's market. For details, please refer to the CrossEx API documentation.

7. How are fund transfer fees charged?

For transfers between exchanges within the CrossEx account or between the CrossEx account and the unified account, Gate charges fees according to the on-chain fee standards of the respective exchange, without any additional on-chain fees. The following two types are internal, off-chain transfers and incur no fees:

• USDT transfers under the cross-exchange margin mode.
• Transfers between the unified account and CrossEx account within Gate, under any mode.

8. How do you check trading fees?

CrossEx account trading fees generally follow the Gate VIP fee schedule, combined with exchange-specific rules and restrictions. At higher Gate VIP levels, CrossEx fees may differ from Gate VIP fees. Please refer to /api/v4/crossex/fee for details.

9. Do you need to create API Keys and sub-accounts on other exchanges?

No. CrossEx account assets can be traded directly on other exchanges via the CrossEx API.

10. What are the differences between exchanges?

CrossEx handles margin calculation, risk control rules, and API request routing. Differences between exchanges mainly involve parameter configurations, such as funding rates, order parameters, contract tiers, debt tiers, discount rates, collateral ratios, interest deductions, and liquidation procedures.

11. Is there an insurance fund?

Yes, there is an insurance fund. During forced liquidation, a 2% liquidation fee is charged. The remaining balance of the liquidation fee is used to establish an insurance fund to cover losses from liquidation shortfalls.

12. How do you switch margin modes?

Switch to single-exchange margin mode:

• Switch conditions: No initial margin, no maintenance margin, no contract positions, no leveraged positions, no open orders.
• Switch method: Use /api/v4/crossex/accounts to switch.
• Asset changes: All CROSSEX_USDT equity is converted to GATE_USDT, and other assets are mapped to their respective exchanges.
• Position mode: If all exchanges have the same position mode, it remains unchanged; otherwise, one-way position mode is used.

Switch to cross-exchange margin mode:

• Switch conditions: No initial margin, no maintenance margin, no contract positions, no leveraged positions, no open orders.
• Switch method: Use /api/v4/crossex/accounts to switch.
• Asset changes: All CROSSEX_USDT equity is converted to GATE_USDT, and other assets are mapped to their respective exchanges.
• Position mode: Contract position mode remains unchanged.

13. Are there frequency limits for Hyperliquid order placement? How is the quota calculated?

Each Hyperliquid account has a default quota of 100 order placement API requests. Each order request consumes 1 quota; after a successful order, each filled 1 USDC increases the quota by 1. When the quota is exhausted, only 1 order placement request can be made every 10 seconds until the quota is restored.

14. How do you query trading pairs that support only isolated margin?

You can use the trading pair rules API GET /api/v4/crossex/rule/symbols to check if cross-margin is supported: when the returned field support_cross is false, it means the trading pair supports only isolated margin.

15. How do you repay Hyperliquid USDC debt?

If your Hyperliquid account has a USDC debt, you can repay it as follows:

Method 1: Repay via Instant Conversion

1. Call the instant conversion quote API POST /crossex/convert/quote to get a quote for converting CrossEx USDT to Hyperliquid USDC.
2. After confirming the quote, call the instant conversion order API POST /crossex/convert/orders to submit the conversion order.
3. Once the conversion is successful, the obtained Hyperliquid USDC will be used first to repay the corresponding USDC debt.
4. After the debt is cleared, any remaining Hyperliquid USDC can be converted back to CrossEx USDT via the same instant conversion API.

Method 2: Repay via fund transfer
You can also transfer USDC from your SPOT account to your Hyperliquid account. Upon successful transfer, the incoming USDC will be used first to repay the Hyperliquid USDC debt.
No interest is charged on Hyperliquid USDC debt amounts up to 10,000 USDC; when the debt exceeds 10,000 USDC, only the portion above 10,000 USDC accrues interest. You can check the specific interest rate via GET /crossex/interest_rate.
