The convergence of traditional finance and the digital asset world is accelerating at a remarkable pace, and one of the most significant developments this summer is set to unfold on Wall Street. The U.S. stock market is poised to debut its first staking-based cryptocurrency ETF—a move that could redefine how investors access yield-generating blockchain opportunities.
This new financial product, symbolized as SSK, will launch on Wednesday and is brought to market by REX Shares in partnership with digital asset manager Osprey. With an expense ratio of just 0.75%, the ETF focuses on Solana (SOL), combining direct exposure to the cryptocurrency with active staking operations designed to generate additional returns.

What Makes a Staking-Based ETF Different?
Unlike existing spot Bitcoin or Ethereum ETFs that simply hold and track the price of the underlying crypto asset, a staking-based ETF goes a step further. It not only holds the digital asset but also participates in the blockchain’s consensus mechanism—specifically, the Proof-of-Stake (PoS) system.
In PoS blockchains like Solana and Ethereum, network security relies on validators who lock up (or "stake") their tokens to verify transactions and create new blocks. In return, they earn rewards—typically a share of transaction fees and newly minted tokens. By integrating staking into the ETF structure, investors gain exposure not just to price appreciation but also to passive income streams generated by blockchain participation.
This innovation marks a pivotal shift: retail and institutional investors can now access decentralized finance (DeFi)-like yields through a regulated, exchange-traded vehicle—without needing to manage private keys, run validator nodes, or navigate complex crypto platforms.
Bridging Traditional Finance and Decentralized Economics
Strahinja Savic, Head of Data and Strategy at alternative asset trading platform FRNT Financial, views this development as a major milestone in the integration of public markets with crypto-native economic models.
“Allowing ETFs that offer staking yields represents another step forward in the marriage between traditional capital markets and the crypto economy.”
Moreover, this evolution aligns with broader policy trends. With growing support from U.S. policymakers for dollar-backed stablecoins and blockchain-based payment systems, enabling regulated access to staking may help advance financial modernization goals. These ETFs allow investors to indirectly support blockchain networks that process dollar-denominated transactions—potentially laying the groundwork for wider adoption of programmable money.
Regulatory Challenges and Compromises
Bringing a staking ETF to market hasn’t been straightforward. The U.S. Securities and Exchange Commission (SEC) has long maintained a cautious stance toward crypto assets, particularly those that might qualify as securities under federal law.
To navigate regulatory scrutiny, REX Shares and Osprey reached a compromise: at least 40% of the SSK fund’s assets must be invested in registered securities, such as other ETFs or ETPs (exchange-traded products), many of which are domiciled outside the United States. This structural adjustment helps satisfy SEC requirements while still providing meaningful exposure to Solana and its staking rewards.
However, risks remain. Staking introduces operational complexities—including validator performance, slashing penalties for misbehavior, and uncertain tax treatment. In the U.S., tax authorities have yet to issue comprehensive guidance on how staking rewards should be classified or reported—adding another layer of uncertainty for investors.
A New Era for Crypto ETFs: The “Crypto Summer” Begins
The approval of SSK may be just the beginning. Nate Geraci, President of ETF Store, a wealth management solutions firm, believes this launch signals the start of a broader wave.
“This is the opening bell for ‘Crypto Summer.’ We’re likely to see a flood of new ETF filings in the coming months.”
He anticipates that once regulators observe the market’s response to SSK, spot Ethereum ETFs with integrated staking features could soon follow. Given Ethereum’s dominant role in DeFi and smart contracts, such products could unlock billions in potential investor capital seeking yield-bearing digital assets.

Tokenization of Private Stocks: Robinhood Leads the Charge
Beyond crypto ETFs, another transformative trend is gaining momentum—the tokenization of traditional equities. On the same day REX announced its ETF launch, Robinhood revealed plans to offer tokenized shares of OpenAI and SpaceX to European users.
These are pre-IPO companies with massive public interest but historically limited accessibility. Their equity has typically been reserved for insiders and accredited investors. Now, through blockchain-based tokenization, retail investors can trade fractional shares of these private tech giants 24/7, with zero commissions and no bid-ask spreads.
While currently unavailable to U.S. investors due to regulatory constraints, this move underscores a growing trend: real-world assets (RWAs) are being digitized and made tradable on decentralized or hybrid platforms. Robinhood already supports over 200 tokenized stocks and ETFs, operating nearly around the clock.
The market responded enthusiastically—Robinhood’s stock surged 12.7% on Monday, hitting a new all-time high.
Frequently Asked Questions (FAQ)
Q: What is a staking-based cryptocurrency ETF?
A: It's an exchange-traded fund that holds a cryptocurrency like Solana and actively stakes it on the blockchain to earn rewards—providing both price exposure and yield generation in a single investment vehicle.
Q: How does staking work inside an ETF?
A: The fund locks up its crypto holdings as collateral to participate in network validation. In return, it earns staking rewards, which are distributed to shareholders—similar to dividend payouts in traditional ETFs.
Q: Is the SSK ETF available to all U.S. investors?
A: Yes, it trades on U.S. exchanges. However, due to regulatory conditions, only up to 60% of its portfolio can directly hold crypto assets; the rest must be in registered securities.
Q: Are staking rewards taxable?
A: While U.S. tax rules are still evolving, most experts believe staking income is taxable upon receipt. Investors should consult a tax professional for guidance.
Q: Can I stake Bitcoin through this type of ETF?
A: Not currently. Bitcoin uses Proof-of-Work, which doesn’t support staking. These products focus on Proof-of-Stake blockchains like Solana and Ethereum.
Q: Why aren’t tokenized stocks available in the U.S.?
A: Regulatory agencies like the SEC haven’t approved retail trading of tokenized private securities yet. Europe has adopted more flexible frameworks, allowing early adoption there.
Final Thoughts: The Future Is Hybrid
The lines between traditional finance and blockchain-based assets are blurring faster than ever. With innovations like staking-enabled ETFs and tokenized equities, investors now have new pathways to diversify into high-growth digital assets—safely, transparently, and within regulated frameworks.
As adoption grows and regulations evolve, we may soon see a financial ecosystem where crypto yields, real-world assets, and traditional portfolios coexist seamlessly.
