The world of digital assets is expanding beyond Bitcoin and Ethereum, and a recent development has made one lesser-known cryptocurrency more accessible than ever — directly through traditional brokerage accounts.
On Wednesday, the REX-Osprey Solana + Staking ETF (SSK) began trading on the Cboe BZX Exchange, marking a pivotal moment for Solana (SOL). As the sixth-largest cryptocurrency by market cap, Solana has long been viewed as a strong competitor to Ethereum due to its fast transaction speeds and low fees. Now, with the launch of SSK, U.S. investors can gain exposure to Solana without needing to navigate crypto exchanges or manage private keys.
This ETF represents the first U.S.-based fund that invests directly in Solana, opening a new pathway for mainstream adoption. But while it signals progress in crypto’s integration into traditional finance, experts urge caution — especially given the risks tied to smaller digital assets, higher fees, and uncertain demand.

Why Solana? The Rise of an Ethereum Challenger
Solana has carved out a niche in the blockchain ecosystem by offering high throughput and scalability. Unlike Bitcoin, which focuses on being digital gold, or Ethereum, which powers decentralized applications (dApps), Solana aims to deliver speed and efficiency at scale.
With support for smart contracts and decentralized finance (DeFi) platforms, Solana has become a preferred choice for developers building scalable applications. Its native token, SOL, has seen significant volatility — currently trading around $151, down nearly 48% from its all-time high of $294 in January 2025.
Despite the price drop, institutional interest remains strong. The approval of the SSK ETF underlines a shifting regulatory landscape, particularly under a crypto-friendly administration that has encouraged innovation in digital assets.
How SSK Differs From Bitcoin and Ether ETFs
While last year’s spot Bitcoin and Ether ETFs were straightforward — investing 100% directly in their underlying assets — SSK takes a hybrid approach.
According to its prospectus:
- At least 40% of assets are allocated to other Solana-based ETFs, primarily those issued outside the U.S.
- The remainder is invested directly in Solana tokens.
- The fund is structured under the Securities Act of 1940, unlike most spot crypto ETFs governed by the 1933 Act.
This structure allows SSK to offer something unique: staking rewards.
Staking: Passive Income With Risks
Staking involves locking up cryptocurrency to help secure a blockchain network in exchange for rewards. For Solana, staking yields are projected at around 7.3% annually, according to data from staking providers and REX Financial.
This makes SSK the first U.S. crypto ETF to incorporate staking, a feature not available in current Ether ETFs due to past SEC concerns. By passing these rewards to investors, SSK could offer enhanced returns — but with trade-offs.
Risks include:
- Locked-up assets: Staked tokens cannot be sold immediately.
- Network instability: Bugs or malicious attacks could affect validator performance.
- Slashing penalties: Validators may lose part of their stake for misbehavior.
Still, experts like Alex Thorn of Galaxy Digital acknowledge the appeal: “There may be good reasons for investors to wait for other staking-enabled Solana ETFs.” Nine major firms — including Fidelity and VanEck — have filed applications, though they’re still pending SEC approval.
High Fees: A Competitive Disadvantage?
One major concern is cost. SSK carries a management fee of 0.75% and an additional income-tax expense of 0.65%, bringing total annual operating expenses to 1.4%.
Compare that to:
- Most Bitcoin ETFs: 0.25% or lower
- Grayscale Bitcoin Trust (GBTC): Up to 1.5%
While REX Financial argues that SSK offers fair value — especially compared to non-U.S. Solana products that retain staking rewards — the higher fees could deter cost-sensitive investors.

Regulatory Shifts Pave the Way
The SEC previously rejected Solana-based ETFs under the Biden administration, citing concerns over market manipulation and lack of investor protections. But with Bitcoin and Ether ETFs now well-established, regulators appear more open to expanding the category.
Recent moves signal growing acceptance:
- Approval of Grayscale’s Digital Large Cap Fund (GDLC) as a multi-asset ETF (including SOL, XRP, ADA).
- Increased scrutiny easing for smaller cryptos like XRP, Cardano, and Litecoin.
Roxanna Islam of VettaFi expects more ETFs for mid-tier cryptocurrencies by year-end: “They fall into the same category as Solana.”
Demand Uncertainty: Will Investors Bite?
Even with regulatory green lights, demand remains unproven. Data shows a stark contrast between Bitcoin and Ether ETF adoption:
| Asset | Launch Date | Total AUM (as of July 2025) | Inflows Since Launch |
|---|---|---|---|
| Bitcoin ETFs | Jan 2024 | $131.6B | $38.6B |
| Ether ETFs | July 2024 | $9.9B | $4.2B |
Bitcoin’s dominance isn’t just about size — it’s about narrative. Many view Bitcoin as digital gold, a store of value akin to gold or cash. Ether and Solana, however, are seen more as utility tokens powering decentralized apps.
Louis LaValle of Frontier Investments notes: “Ether’s investment use case was not as well played out.” That challenge extends to Solana.
“If these smaller ETFs don’t generate enough demand,” he warns, “providers will shut them down within one or two years.”
FAQ: Your Questions About the Solana ETF Answered
Q: Can I buy the SSK ETF through my regular brokerage account?
A: Yes. SSK trades on the Cboe BZX Exchange under the ticker SSK, making it accessible via most U.S. brokerage platforms like Fidelity, Charles Schwab, and Robinhood.
Q: Does SSK invest 100% in Solana?
A: No. While it holds Solana directly, at least 40% of its portfolio is invested in other Solana ETFs, mostly issued outside the U.S.
Q: What are the tax implications of investing in SSK?
A: Because it’s structured under the 1940 Act, SSK may face higher tax burdens than 1933 Act funds. Investors should consult a tax advisor regarding potential liabilities from staking income and fund distributions.
Q: Is Solana a safer bet than other altcoins?
A: Relative to many altcoins, yes — due to its strong developer community and real-world use cases. But it still carries higher volatility and regulatory risk than Bitcoin or Ethereum.
Q: Will larger firms like BlackRock launch their own Solana ETFs?
A: Multiple institutions have filed applications, but none have been approved yet. Fidelity, Franklin Templeton, and VanEck are among those awaiting SEC decisions.
Q: Can I earn staking rewards without buying SSK?
A: Yes — by holding SOL directly on supported wallets or exchanges. However, doing so requires managing private keys and understanding smart contract risks.

Final Thoughts: Innovation Meets Caution
The launch of the REX-Osprey Solana + Staking ETF marks a milestone in crypto’s journey toward mainstream finance. It brings Solana within reach of everyday investors, offers passive income via staking, and reflects a more welcoming regulatory climate.
Yet challenges remain: high fees, limited initial demand, structural complexity, and lingering questions about long-term viability.
For investors considering SSK or future Solana ETFs, due diligence is key. Understand the risks, compare costs, and assess whether exposure to a high-growth but volatile blockchain aligns with your financial goals.
As the crypto ETF landscape evolves, one thing is clear: the era of niche digital assets entering traditional markets has only just begun.
