Cross-Exchange Account FAQ ｜ Gate

1. What Is a Cross-Exchange Account?

A cross-exchange account, known in English as CrossEx, is a one-stop cross-exchange trading and clearing platform designed 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 model, CrossEx helps users access multiple leading exchanges at an 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;
It supports leverage of up to 50x;
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, improving capital efficiency. The latter supports USDT and other currencies on the corresponding exchange as single-exchange margin, with independent risk management.

3. Which Assets Can Be Transferred Through 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.
Special restrictions:

• CROSSEX_KRAKEN: Only USDT transfers are supported.
• CROSSEX_HYPERLIQUID: Only USDC transfers to and from the SPOT account are supported.

4. What Are the Advantages of CrossEx?

• Unified access: You do not need to open accounts or develop integrations separately for multiple exchanges. Simply connect to the CrossEx API to trade across 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 profits and losses across positions can offset each other, significantly improving capital utilization.
• Unified system: CrossEx provides unified trading, clearing, and independent risk management mechanisms. It abstracts away underlying differences between exchanges, improving the overall trading experience and risk controllability.
• Cost advantage: It offers competitive fee rates to 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 identifier of the specific exchange, 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 query trading pair information through the /api/v4/crossx/rule/symbols API. 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 standard of the relevant exchange and does not impose any additional on-chain fees. The following two types of transfers are internal, non-on-chain transfers and incur no fees:

• USDT transfers under cross-exchange margin mode;
• Transfers involving Gate between unified accounts and cross-exchange accounts 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 tiers, 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 management rules, and routing and distribution of API requests. Differences between exchanges mainly relate to 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. A 2% liquidation fee is charged during forced liquidation and settlement. The remaining liquidation fees are used to establish an insurance fund to cover losses resulting from liquidation deficits.

12. How Do I Switch Margin Modes?

Switching to exchange-specific margin mode

• Switching requirements: The account must have 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 all exchanges use the same position mode, the position mode remains unchanged. Otherwise, one-way mode is used.

Switching to cross-exchange margin mode

• Switching requirements: The account must have 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: The futures position mode remains unchanged.

13. Are There Frequency Limits for Placing Orders on Hyperliquid? How Is the Allowance Calculated?

Each Hyperliquid account has a default allowance of 100 order placement API requests. Each order request consumes 1 allowance unit. After an order is successfully placed, each 1 USDC traded adds 1 allowance unit. Once the allowance is exhausted, you can request the order placement API only once every 10 seconds until the allowance is restored.

14. How Can I Identify Isolated-Margin-Only Trading Pairs?

You can use the trading pair rules API GET /api/v4/crossex/rule/symbols to check whether cross margin is supported. If the returned support_cross field is false, the trading pair is isolated-margin only.

15. How Do I Repay Hyperliquid USDC Debt?

If your Hyperliquid account has USDC debt, you can repay it using the following methods:

Method 1: Repay Through Convert

1. Call the convert quote API POST /crossex/convert/quote to obtain a quote for converting CrossEx USDT to Hyperliquid USDC.
2. After confirming the quote, call the convert trading API POST /crossex/convert/orders to submit the conversion order.
3. Once the conversion is successful, the resulting Hyperliquid USDC will be used first to repay the corresponding USDC debt.
4. 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. After the transfer is completed, the transferred USDC will be used first to repay Hyperliquid USDC debt.

Interest Rules
USDT/USDC debt incurred in a CrossEx account accrues interest. USDC debt in a Hyperliquid account includes an interest-free allowance of 10,000 USDC, and only the amount exceeding this allowance accrues interest. You can query the hourly interest rates for assets on each exchange through GET /crossex/interest_rate.

16. What Are CrossEx's ADL Ranking Rules?

CrossEx does not perform matching itself. ADL occurs natively on each exchange, and you should refer to each exchange's ADL rules for its ADL ranking criteria.
You can use the API GET /api/v4/crossex/adl_rank to view ADL ranking information for positions. API documentation takes precedence. The response includes the following two fields:

• exchange_adl_rank: The rank of the overall CrossEx position in the upstream exchange's ADL queue. Exchange priorities from highest to lowest are as follows:
  • BINANCE: 4, 3, 2, 1, 0
  • OKX: 5, 4, 3, 2, 1, 0
  • GATE: 1, 2, 3, 4, 5
  • Kraken: 20, 40, 60, 80, 100
  • BYBIT: 5, 4, 3, 2, 1, 0
• crossex_adl_rank: Your ADL ranking among users trading the same pair within CrossEx. Priority from highest to lowest is 5, 4, 3, 2, 1;

Only after an upstream exchange actually executes partial ADL on CrossEx positions will CrossEx passively reduce the positions of relevant users according to crossex_adl_rank, at the same price and in the same direction.
Therefore, Binance ADL rank may be low while crossex_adl_rank is 5. For example, if few users participate in the ranking for that trading pair on CrossEx, you may rank near the top of the internal queue. However, as long as the upstream exchange has not triggered ADL, CrossEx will not proactively reduce your position solely because your crossex_adl_rank is high.
