1. What Is a Cross-Exchange Account?
The English name for the cross-exchange account is CrossEx. It is a one-stop cross-exchange trading, clearing, and settlement platform for professional investors, quantitative teams, and institutions. Powered by a unified cross-exchange account system, low-latency order matching and execution, and a unified cross-exchange clearing and settlement model, CrossEx helps users access multiple leading exchanges at extremely low cost. It enables shared margin across exchanges, significantly improving trade execution quality and capital efficiency.
2. What Services Does a Cross-Exchange Account Support?
In terms of trading types, it supports spot trading, cross-margin trading, and USDT-margined perpetual futures;
In terms of leverage, it supports up to 50x leverage;
In terms of position modes, it supports one-way mode and hedge mode;
In terms of position margin modes, it supports cross-margin mode and isolated-margin mode (Hyperliquid only);
In terms of account margin modes, it supports cross-exchange margin mode and exchange-specific margin mode. The former supports USDT, BNB, BTC, ETH, SOL, XRP, USDC, KRAKEN_USD, and HYPERLIQUID_USDC as unified cross-exchange margin currencies for centralized risk management and improved capital efficiency. The latter supports USDT and other currencies on the corresponding exchange as single-exchange margin for independent risk management.
3. Which Assets Can Be Transferred in a Cross-Exchange Account?
Currently, the following assets can be transferred bidirectionally within a cross-exchange account or between a cross-exchange account and a unified account through the fund transfer API: USDT, BTC, ETH, XRP, BNB, SOL, TRX, DOGE, ADA, SUI, AVAX, LTC, and DOT. For details, refer to the /api/v4/crossex/transfers/coin API information.
Special restrictions:

4. What Are the Advantages of CrossEx?
- Unified access: You do not need to open accounts and develop separately for multiple exchanges. Simply integrate the CrossEx API to trade on multiple exchanges simultaneously, significantly reducing the technical and operational barriers to cross-exchange trading.
- Improved capital efficiency: CrossEx provides cross-exchange margin and fund transfer capabilities. A single USDT balance can be shared across multiple exchanges, and PnL across positions can offset each other, significantly improving capital utilization.
- Unified system: CrossEx offers unified trading, clearing and settlement, and independent risk control mechanisms. It eliminates underlying differences between exchanges, improving the overall trading experience and risk controllability.
- Cost advantage: It offers competitively priced fee rates that meet the needs of retail users, Brokers, and institutional clients, helping you reduce trading costs.
5. How Can I Distinguish Assets in a Cross-Exchange Account?
- When assets in a cross-exchange account are held on different exchanges, the symbol includes the specific exchange identifier, such as BINANCE_FUTURE_ADA_USDT or OKX_FUTURE_ADA_USDT;
- When USDT is used as unified cross-exchange margin, the symbol does not include an exchange identifier.
6. How Do I Trade With a Cross-Exchange Account?
Cross-exchange accounts support API trading only.
You can use the /api/v4/crossx/rule/symbols API to query trading pair information. The returned symbol field identifies the corresponding exchange and market type (for example, BINANCE_FUTURE_ADA_USDT or OKX_FUTURE_ADA_USDT). Only assets with matching symbols can be traded in the corresponding market on that exchange. For details, refer to the CrossEx API documentation.
7. How Are Fund Transfer Fees Charged?
For transfers between exchanges within a cross-exchange account or between a cross-exchange account and a unified account, Gate charges fees according to the on-chain fee standards of the relevant exchange, without any additional on-chain fees. The following two types of transfers are internal, non-on-chain transfers and do not incur any fees:
- USDT transfers under cross-exchange margin mode;
- Transfers of Gate assets between the unified account and the cross-exchange account under all modes.
8. How Can I Check Trading Fees?
Cross-exchange account trading fees generally follow the Gate VIP fee schedule, while also taking into account fee rules and restrictions of other exchanges. At higher Gate VIP levels, cross-exchange fees may differ from Gate VIP fees. For specific fees, refer to /api/v4/crossex/fee.
9. Do I Need to Create API Keys and Sub-accounts on Other Exchanges?
No. Assets in a cross-exchange account can be traded directly on other exchanges through the CrossEx API.
10. What Are the Differences Between Exchanges?
CrossEx is responsible for margin calculations, risk control rules, and the routing and distribution of API requests. The main differences between exchanges lie in parameter configurations, such as funding rates, order parameters, contract tiers, debt tiers, discount rates, collateral ratios, interest charges, forced liquidation, and settlement.
11. Is There an Insurance Fund?
Yes, there is an insurance fund. A 2% liquidation fee is charged during forced liquidation. The remaining liquidation fees are used to establish an insurance fund that covers losses resulting from liquidation deficits.
12. How Do I Switch Margin Modes?
Switch to exchange-specific margin mode
- Switching requirements: The account has no initial margin, maintenance margin, futures positions, margin positions, or open orders;
- Switching method: Switch through /api/v4/crossex/accounts;
- Asset changes: All equity in CROSSEX_USDT is converted to GATE_USDT, while other assets are mapped to their respective exchanges;
- Position mode: If the position modes are the same across all exchanges, the position mode remains unchanged. Otherwise, one-way mode is used.
Switch to cross-exchange margin mode
- Switching requirements: The account has no initial margin, maintenance margin, futures positions, margin positions, or open orders;
- Switching method: Switch through /api/v4/crossex/accounts;
- Asset changes: All equity in CROSSEX_USDT is converted to GATE_USDT, while other assets are mapped to their respective exchanges;

13. Are There Order Frequency Limits for Hyperliquid? How Is the Quota Calculated?
Each Hyperliquid account has a default quota of 100 order placement API requests. Each order placement request consumes 1 quota. After an order is successfully placed, the quota increases by 1 for every 1 USDC traded. After the quota is exhausted, you can submit only 1 order placement API request every 10 seconds until the quota is restored.
14. How Can I Check Trading Pairs That Support Isolated Margin Only?
You can use the trading pair rules API GET /api/v4/crossex/rule/symbols to check whether cross margin is supported. When the returned support_cross field is false, the trading pair supports isolated margin only.
15. How Do I Repay Hyperliquid USDC Debt?
If your Hyperliquid account has USDC debt, you can repay it in the following ways:
Method 1: Repay Through Convert
- Call the Convert quote API POST /crossex/convert/quote to obtain a quote for converting CrossEx USDT to Hyperliquid USDC.
- After confirming the quote, call the Convert trading API POST /crossex/convert/orders to submit the conversion order.
- Once the conversion is completed, the resulting Hyperliquid USDC will be used first to repay the corresponding USDC debt.
- After the debt is fully repaid, any remaining Hyperliquid USDC can also be converted back to CrossEx USDT through the Convert APIs above.
Method 2: Repay Through Fund Transfer
You can also transfer USDC from SPOT to your Hyperliquid account. Once the transfer is completed, the transferred USDC will be used first to repay the Hyperliquid USDC debt.
Interest Rules
USDT/USDC debt incurred in a CrossEx account accrues interest. USDC debt in a Hyperliquid account has an interest-free allowance of 10,000 USDC, and interest is charged only on the amount exceeding this allowance. You can query the hourly interest rates for assets on each exchange through GET /crossex/interest_rate.
