The world of digital assets is expanding into traditional finance like never before. A new exchange-traded fund (ETF) has launched, allowing investors to gain exposure to Solana (SOL)—a high-performance blockchain platform—directly through standard brokerage accounts. This marks a pivotal development in the mainstream adoption of cryptocurrencies beyond Bitcoin and Ethereum.
The REX-Osprey Solana + Staking ETF, trading under the ticker SSK, began trading on the Cboe BZX Exchange and represents the first U.S.-listed ETF to hold Solana directly. Unlike previous crypto ETFs that focused solely on Bitcoin or Ether, SSK opens the door to alternative digital assets, potentially setting a precedent for future ETFs tied to mid-tier cryptocurrencies like XRP, Cardano, and Litecoin.

Why Solana Matters in the Crypto Ecosystem
Solana ranks as the sixth-largest cryptocurrency by market capitalization and is widely regarded as one of Ethereum’s most formidable competitors. Its blockchain supports fast transaction speeds and low fees, making it a preferred platform for decentralized applications (dApps), non-fungible tokens (NFTs), and Web3 infrastructure.
With the launch of SSK, retail investors can now access Solana without needing to navigate cryptocurrency exchanges, wallets, or private keys—removing significant barriers to entry. Greg King, CEO of REX Financial and Osprey Funds, anticipates initial demand will come primarily from individual investors, with institutional adoption following gradually.
“This is about bringing crypto into the mainstream financial system,” King said in an interview. “We’re meeting investors where they already are—through their brokerage accounts.”
How the SSK ETF Works Differently
Unlike pure-play Bitcoin or Ether ETFs—which invest 100% directly in their underlying assets—SSK operates under a hybrid model. According to its prospectus, the fund allocates at least 40% of its holdings to other Solana-based ETFs, mostly issued outside the U.S., while the remainder is invested directly in Solana tokens.
This structure introduces diversification but also complexity. However, experts like Roxanna Islam, head of sector research at VettaFi, argue that since all underlying assets are tied to Solana, foreign exposure doesn’t significantly increase risk. Additionally, the fund aims to minimize currency fluctuations by investing in USD-denominated share classes.
A key innovation: SSK is the first crypto ETF to incorporate staking.
Staking involves locking up cryptocurrency to support network operations and earn rewards. For Solana, projected annual staking yields hover around 7.3%, according to data from multiple staking providers. These returns are passed on to investors, offering a source of passive income—a feature absent in most existing Ether ETFs due to regulatory concerns.
“Staking adds yield potential, which could be a major draw,” said Alex Thorn, head of firmwide research at Galaxy Digital. “But investors should understand the risks—tokens are locked, and there's exposure to network vulnerabilities or slashing penalties.”
Regulatory Shifts Pave the Way
The approval of SSK reflects a notable shift in the U.S. regulatory landscape. While the Securities and Exchange Commission (SEC) rejected Solana-based ETFs in 2024 under the Biden administration—citing manipulation risks—the Trump administration has adopted a more crypto-friendly stance.
Recent actions include establishing a national Bitcoin reserve and approving multi-asset crypto ETFs. Notably, the SEC recently greenlit the conversion of Grayscale’s Digital Large Cap Fund (GDLC) into an ETF that holds Bitcoin, Ether, Solana, XRP, and Cardano—marking the first time a U.S. regulator approved an ETF with broad exposure beyond BTC and ETH.

Islam expects further approvals by year-end for ETFs linked to XRP, Cardano, and other established altcoins. “Solana’s approval sets a template,” she noted. “These assets fall into a similar category—proven networks with real-world use cases.”
Fees and Competition: What Investors Should Know
One concern surrounding SSK is cost. The fund carries a management fee of 0.75% and an additional income-tax expense of 0.65%, resulting in total annual operating expenses of 1.4%—significantly higher than most spot Bitcoin ETFs, which typically charge 0.25% or less.
While Grayscale’s GBTC charges up to 1.5%, many investors expect newer entrants like Fidelity or VanEck—currently awaiting SEC decisions on their own Solana ETF proposals—to offer lower fees upon approval.
“SSK may have first-mover advantage,” Thorn observed, “but long-term success depends on fee competitiveness and institutional backing.”
King defends the pricing: “Compared to non-U.S. Solana products that retain staking rewards, we’re delivering net value. Our structure allows investors to benefit fully from staking yields.”
Will There Be Enough Demand?
Despite these innovations, demand remains uncertain. Data shows a stark contrast between Bitcoin and Ether ETF performance: as of July 2024, Bitcoin ETFs held $131.6 billion in assets versus just $9.9 billion for Ether ETFs. Inflows tell a similar story—$38.6 billion for Bitcoin vs. $4.2 billion for Ether since launch.
“Bitcoin’s dominance isn’t just market cap—it’s narrative strength,” said Louis LaValle of Frontier Investments. “It’s seen as digital gold. Ethereum and Solana are tech platforms, not stores of value.”
If Ether ETFs struggle to attract capital, smaller-cap crypto ETFs may face even steeper challenges.
Frequently Asked Questions (FAQ)
Q: What is the REX-Osprey Solana + Staking ETF (SSK)?
A: SSK is the first U.S.-listed ETF that provides direct exposure to Solana (SOL) through traditional brokerage accounts. It also stakes its holdings to generate yield for investors.
Q: How does SSK differ from Bitcoin or Ether ETFs?
A: Unlike pure-play BTC or ETH ETFs, SSK invests at least 40% in other Solana-related funds and incorporates staking—a feature not available in current U.S.-listed Ether ETFs.
Q: Is staking safe? Can I lose money?
A: Staking offers yield but comes with risks. Tokens are locked and vulnerable to penalties if validators act maliciously or the network experiences instability.
Q: Why are fees higher for SSK?
A: Higher costs stem from its structure under the Investment Company Act of 1940 and investments in foreign exchange-traded products. Most Bitcoin ETFs operate under the lighter-touch Securities Act of 1933.
Q: Are more altcoin ETFs coming?
A: Yes. The SEC’s approval of multi-asset and Solana-based funds signals growing openness. Experts predict potential approvals for XRP, Cardano, and Litecoin ETFs by late 2025.
Q: Should I invest in SSK or wait for competitors?
A: Consider your priorities. SSK offers early access and staking rewards, but future entrants from firms like Fidelity may offer lower fees and stronger institutional credibility.
