Cryptocurrency exchanges KuCoin, Gate and OKX have introduced separate changes to their trading infrastructure and derivatives businesses, expanding broker API functionality and access to financial instruments linked to traditional stock markets.
KuCoin scheduled a September 21 API upgrade addressing broker order identification and trading data. Gate launched U.S. equity options covering nine major companies on September 2, while OKX added perpetual futures referencing U.S. equity indices and Exxon Mobil on September 10.
The developments affect different parts of exchange operations, from the systems used by third-party trading terminals to the range of derivatives available to individual customers.
They also highlight an increasingly important distinction for crypto investors: access to a stock-linked financial product through a cryptocurrency exchange does not necessarily provide ownership of the underlying shares or the same trading conditions found at conventional securities brokers.
KuCoin Updates Broker APIs and Trading Data
KuCoin’s September 21 infrastructure upgrade introduced changes to its Unified Trading Account API, including a dedicated field designed to identify broker-originated orders.
The new brokerTag parameter supports strings of up to 50 characters and is available through UTA REST and WebSocket order interfaces.
Previously, broker identifiers were tied to an existing order-tagging field subject to a 20-character limit.
According to KuCoin’s September 16 announcement, the change separates broker identification from that restriction and addresses order failures associated with the previous implementation.
The distinction matters for trading platforms connecting customers to KuCoin through third-party brokers, applications and automated execution systems.
Such intermediaries rely on API identifiers to associate orders with the correct distribution channel and maintain accurate transaction records.
KuCoin also introduced additional profit-and-loss information through its trading interfaces.
A new fillPnl field was added to UTA trade-history responses, while WebSocket execution messages gained a corresponding fP field.
However, historical profit-and-loss data predating September 5, measured in UTC-8, is not available through those fields.
The upgrade also adds assetClass and subMarketType to symbol-information responses, replacing reliance on the existing marketType field, which KuCoin marked as deprecated.
These changes are relevant to developers and brokers whose software depends on exchange metadata remaining consistent.
KuCoin warned that WebSocket connections could experience temporary interruptions, delays or data loss during the scheduled two-hour maintenance window.
Gate Launches U.S. Stock Options With USDT Settlement
Gate’s September 2 expansion introduced options linked to nine major U.S. equities: Nvidia, Tesla, Apple, Meta Platforms, Advanced Micro Devices, Micron Technology, Amazon, Alphabet and Broadcom.
The products allow eligible customers to trade options through Gate without separately opening a conventional U.S. stock brokerage account.
However, the contracts settle financially rather than through delivery of underlying securities.
That means an investor who holds an option through settlement receives the applicable cash-settlement outcome instead of shares in the referenced company.
Gate’s trading arrangements use USDT for settlement, connecting equity-linked derivatives to the dollar-denominated infrastructure already used extensively across cryptocurrency markets.
Unlike cryptocurrency perpetual futures, the stock options follow regular U.S. equity-market trading hours.
The exchange’s documentation describes trading during the 9:30 a.m. to 4 p.m. Eastern Time session, with settlement calculations based on stock-price information shortly before the market close.
These mechanics create differences between holding the underlying equity, trading an exchange-listed option through a traditional broker and trading a cash-settled equity-linked product through Gate.
Options buyers face the possibility of losing their entire premium, while options sellers may incur larger losses depending on the strategy and applicable risk controls.
OKX Adds U.S. Equity and Index Perpetual Futures
OKX took a different approach to traditional-market derivatives with its September 10 listing of three USDT-margined perpetual futures.
The contracts reference the US500 and US100 equity indices and Exxon Mobil, the publicly traded energy company.
OKX scheduled the contracts to begin trading at 09:00, 09:15 and 09:30 UTC, respectively.
Unlike traditional equity futures with specified expiration dates, the new instruments use a perpetual structure with no scheduled maturity.
They are available for trading around the clock, including periods when the conventional U.S. equity markets are closed.
The exchange applies periodic funding payments to help keep perpetual contract prices aligned with their reference markets.
Its published specifications establish an eight-hour funding settlement interval, which can automatically shorten to one hour when funding rates reach prescribed limits.
For retail traders, funding is a material part of the cost of maintaining a position.
A leveraged trader can incur funding expenses even when the reference asset’s price remains relatively stable.
Continuous trading also creates price-discovery challenges when the traditional securities or indices referenced by the contracts are not actively trading on their primary markets.
OKX states that product availability depends on the customer’s jurisdiction and account eligibility.
Different Products Create Different Trading Risks
Although Gate and OKX have both expanded into traditional financial markets, their derivatives are not interchangeable.
Gate’s stock options expose customers to premium pricing, strike selection, expiration and cash settlement.
OKX’s perpetual futures instead involve ongoing funding payments, leverage requirements and liquidation risk without a fixed contract expiration.
KuCoin’s changes concern the infrastructure used to route and monitor trades rather than the introduction of a comparable equity derivative.
Taken together, the announcements show how cryptocurrency exchange development is extending across multiple layers of the trading business.
Broker integrations require reliable APIs and accurate order information. Stock-linked derivatives require pricing and settlement systems that interact with conventional financial markets. Perpetual contracts require funding mechanisms and risk controls capable of operating continuously.
For customers, the expanding range of instruments also makes product classification more important.
A contract referencing Nvidia, an equity index or another familiar market does not automatically give its holder the rights associated with owning that underlying asset.
Trading costs, liquidity, settlement procedures and legal protections depend on the specific product and entity providing it.
Exchanges Are Competing on Market Access and Execution
The recent developments suggest that crypto exchanges are building more complex trading environments rather than simply adding cryptocurrencies to existing order books.
KuCoin’s broker API changes address execution infrastructure and integration reliability.
Gate’s stock options extend the range of instruments customers can access through cryptocurrency-funded accounts.
OKX’s perpetual listings bring additional traditional-market exposure into continuously operating derivatives markets.
None of these changes establishes that customers will receive better execution or lower total trading costs than they would through conventional brokers.
Those outcomes depend on spreads, market depth, funding charges, available liquidity and the quality of the relevant trading infrastructure.
The broader significance is that cryptocurrency exchanges are increasingly offering multiple ways to access financial markets that were previously associated mainly with securities and derivatives brokerages.
For retail traders, understanding the contractual structure behind each instrument is becoming as important as recognizing the asset it tracks.
