Tapbit TradFi continues to expand its stock ETF contract lineup.
The ninth phase of Tapbit TradFi stock ETF contracts is scheduled to go live on July 14, 2026 at 15:00 (UTC+8), adding seven new USDT contract pairs:
These new contract pairs cover several different market themes: U.S. technology stocks, Nasdaq-100 bullish and bearish exposure, volatility trading, Japan equities, South Korea equities, China technology exposure and AI chip infrastructure.
For traders, the most important point is not only what each ETF tracks. It is also how these products behave.
Some of the newly added names are leveraged ETFs. Some are inverse or volatility-linked products. These instruments can move sharply and may be affected by compounding, daily reset mechanics and volatility decay.
This guide explains what each pair represents and what users should know before trading.
What Are ETF Contracts on Tapbit?
ETF contracts on Tapbit allow users to trade price exposure linked to selected ETF markets using USDT contract pairs.
When trading these pairs, users are not directly buying shares of the underlying ETF. Instead, they are trading contract exposure based on the relevant ETF market. This structure gives users another way to access traditional market themes through Tapbit’s TradFi contract product line.
Because many ETF products are designed for specific tactical views, users should always understand the underlying asset, leverage structure, direction and risk profile before opening a position.
This is especially important for leveraged, inverse and volatility-linked ETFs.
Newly Added Tapbit ETF Contract Pairs
SKHYUSDT: SK Hynix U.S. Stock Contract
SKHY is linked to the U.S.-listed shares of SK Hynix on NASDAQ. SK Hynix is a leading South Korean memory chipmaker and a key supplier of high-bandwidth memory (HBM) used in AI servers. In July 2026, SK Hynix completed its NASDAQ IPO, raising about $26.5 billion, making it one of the largest U.S. listings by a foreign company.
This makes SKHY a high-interest contract for traders watching AI memory, semiconductor demand, DRAM cycles and South Korean technology stocks.
SK Hynix is closely followed because of its exposure to HBM, DRAM, NAND, AI infrastructure and global chip supply chains. SKHY may attract traders who want exposure to the company’s U.S.-listed stock momentum, but users should note that this contract tracks SK Hynix’s U.S. shares, not the previously listed SK Hynix Korean stock contract. The two products are linked to the same company but different listing venues and price references.
MVLLUSDT: Marvell 2X Long ETF Contract
MVLL is linked to 2x long exposure to Marvell Technology, a semiconductor company connected to AI networking, custom silicon and data infrastructure themes.
This product is designed for traders with a bullish short-term view on Marvell-related market movement. Because MVLL is a single-stock leveraged ETF-style exposure, it may be more volatile than the underlying stock.
For users, the key point is that single-stock leveraged products can react sharply to company-specific news, earnings, AI chip sentiment, analyst ratings and broader semiconductor sector moves.
MVLL may be useful for traders watching AI infrastructure and custom chip narratives, but it requires strict risk control because leverage can magnify both gains and losses.
TQQQUSDT: Nasdaq-100 3X Bull ETF Contract
TQQQ is linked to the ProShares UltraPro QQQ ETF. ProShares states that TQQQ seeks daily investment results equal to three times the daily performance of the Nasdaq-100 Index before fees and expenses. ProShares also notes that returns over periods longer than one day can be higher or lower than the daily target due to compounding and volatility effects.
TQQQ is one of the best-known leveraged ETF products for traders who want bullish exposure to large U.S. technology and growth stocks.
It is often watched when markets are focused on AI, semiconductors, software, cloud computing, mega-cap technology and risk appetite. However, because TQQQ targets 3x daily exposure, it is generally more suitable for short-term market views than long-term holding.
SQQQUSDT: Nasdaq-100 3X Bear ETF Contract
SQQQ is the bearish counterpart to TQQQ.
ProShares states that SQQQ seeks daily investment results equal to three times the inverse (-3x) of the daily performance of the Nasdaq-100 Index before fees and expenses. The issuer describes SQQQ as a product designed to profit when the daily price of the Nasdaq-100 Index declines and notes that results over holding periods longer than one day may differ significantly from the daily target.
SQQQ may be used by traders with a bearish short-term view on the Nasdaq-100 or by users looking to hedge technology-market exposure.
However, inverse leveraged ETFs can be difficult to hold for extended periods. If the Nasdaq-100 rises, SQQQ can fall sharply. If the market swings back and forth, compounding effects can also reduce performance over time.
KSTRUSDT: China STAR Market 50 ETF Contract
KSTR is linked to the KraneShares SSE STAR Market 50 Index ETF.
KraneShares states that KSTR seeks to track the Shanghai Stock Exchange Science and Technology Innovation Board 50 Index, also known as the STAR 50 Index. The index includes the 50 largest companies listed on China’s STAR Market based on market capitalization and liquidity.
KSTR gives traders exposure to China’s technology and innovation sector, including areas such as semiconductors, next-generation information technology, biomedicine, new energy and environmental protection. KraneShares describes the STAR Market as a venue for innovation-driven science and technology companies.
Unlike KORU, TQQQ or SQQQ, KSTR is not a 3x leveraged ETF. It represents a thematic China technology equity exposure.
UVXYUSDT: VIX Short-Term Futures Volatility ETF Contract
UVXY is linked to short-term VIX futures exposure. Investopedia describes the ProShares Ultra VIX Short-Term Futures ETF as a product seeking results equal to 1.5 times the daily performance of the S&P 500 VIX Short-Term Futures Index.
UVXY is different from equity ETFs.
It is tied to volatility futures, not company earnings or stock index direction alone. It is often associated with market fear, hedging demand and sudden spikes in risk aversion.
Because volatility ETFs are complex, they are generally viewed as short-term tactical tools. Products linked to VIX futures can experience significant decay over time, especially when futures curve conditions work against holders. Investopedia notes that VIX-related ETFs are complicated and are generally more suitable for experienced investors.
EWJUSDT: Japan ETF Contract
EWJ is linked to the iShares MSCI Japan ETF.
BlackRock states that EWJ seeks to track an index composed of Japanese equities and provides a way to express a single-country view on Japan. The fund’s benchmark index is the MSCI Japan Index.
EWJ gives traders exposure to Japan’s large and mid-sized equity market. Japan remains important to global investors because of its role in autos, electronics, industrial automation, financials, robotics and advanced manufacturing.
Compared with leveraged products, EWJ is a more traditional country ETF exposure. It may appeal to users watching Japan equity trends, yen-related macro conditions, Bank of Japan policy, export demand and Japanese corporate reform themes.
Understanding Leveraged ETF Risk
Many of the newly added products involve leverage or inverse exposure.
Leveraged ETFs usually aim to deliver a multiple of the daily performance of an underlying asset or index. For example, a 3x daily bull ETF targets three times the daily move of the benchmark. An inverse 3x product targets three times the opposite of the benchmark’s daily move.
This structure can create strong short-term movement, but it also creates risk.
Academic research on leveraged ETFs highlights that daily leveraged funds can deviate from simple long-term multiples because of compounding and volatility effects. A 2026 paper studying leveraged ETF behavior found that volatility and compounding explain a large part of why 2x and 3x daily return products may underperform simple expectations over longer holding periods.
This is why leveraged ETF contracts are usually better understood as short-term trading tools, not passive long-term holding instruments.
Key Risk Controls Before Trading
Before trading ETF contracts, users should consider several practical risk-control steps.
First, understand the underlying market. Do not trade TQQQUSDT without understanding Nasdaq-100 direction. Do not trade UVXYUSDT without understanding volatility futures.
Second, check whether the product is leveraged or inverse. Leveraged products can amplify losses as well as gains.
Third, avoid treating daily leveraged products as simple long-term investments. Daily reset mechanics can cause performance to differ from expected long-term multiples.
Fourth, use position sizing carefully. High-volatility products can move sharply within a short period.
Fifth, watch macro catalysts. ETF contracts can react to earnings, central bank decisions, inflation data, geopolitical headlines, semiconductor news and broader risk sentiment.
Sixth, manage liquidation risk. USDT contract trading can involve leverage at the platform level, while some underlying ETFs may already contain embedded leverage. This creates layered risk.

Tapbit View
Tapbit TradFi Phase 9 expands the platform’s ETF contract coverage across technology, volatility and international equity markets.
The addition of SKHYUSDT, MVLLUSDT, TQQQUSDT, SQQQUSDT, KSTRUSDT, UVXYUSDT and EWJUSDT gives users more ways to trade global market themes through USDT contract pairs.
Leveraged and inverse products can be powerful tools, but they are not simple. They are designed around daily exposure, short-term market views and active risk management. Volatility-linked products such as UVXY can behave differently from normal equity ETFs and may experience long-term decay.
For Tapbit users, the key lesson is clear: understand the underlying asset before trading the contract. Trade with risk control. Not investment advice.
