Trading ETF Contracts on Tapbit: Phase 9 Listings & Risks

Tapbit is rolling out the ninth phase of its TradFi stock ETF contract lineup on July 14, 2026, at 15:00 (UTC+8). The crypto derivatives platform will add seven USDT-quoted pairs: SKHYUSDT, MVLLUSDT, TQQQUSDT, SQQQUSDT, KSTRUSDT, UVXYUSDT and EWJUSDT. The contracts provide exposure to selected ETF markets rather than direct ownership of the underlying ETFs.

New pairs at a glance

• SKHYUSDT tracks the U.S.-listed shares of SK Hynix on Nasdaq, after the South Korean memory chipmaker’s July 2026 IPO raised about $26.5 billion, one of the largest U.S. listings by a foreign company.
• MVLLUSDT is linked to a 2x long single-stock ETF tied to Marvell Technology, adding leverage to AI networking and custom silicon themes.
• TQQQUSDT references ProShares UltraPro QQQ, which targets three times the daily performance of the Nasdaq-100 Index.
• SQQQUSDT references ProShares UltraPro Short QQQ, which seeks minus three times the daily Nasdaq-100 return.
• KSTRUSDT is based on the KraneShares SSE STAR Market 50 Index ETF, tracking the 50 largest companies on China’s STAR Market.
• UVXYUSDT is linked to the ProShares Ultra VIX Short-Term Futures ETF, which targets 1.5 times the daily performance of short-term VIX futures.
• EWJUSDT references the iShares MSCI Japan ETF, offering broad exposure to Japanese large- and mid-cap equities.

The lineup includes leveraged and inverse products that reset daily, so compounding and volatility decay can cause returns to diverge from a simple multiple of the underlying index over longer holding periods. Tapbit pointed to a 2026 academic paper that found volatility and compounding explain much of the underperformance of 2x and 3x daily products. Volatility-linked instruments such as UVXY can also erode in value over time depending on futures curve conditions.

Tapbit said traders should understand the underlying market before opening a position, check whether the contract is leveraged or inverse, avoid using daily-reset products as long-term investments, size positions carefully and watch macro catalysts. The exchange also warned about layered liquidation risk, since platform-level margin leverage can combine with embedded leverage in the underlying ETF.
