The U.S. financial markets are on the cusp of a groundbreaking development in digital asset investing — the debut of the nation’s first Solana staking-enabled ETF. With regulatory winds shifting under the current administration, the launch of the REX-Osprey Sol + Staking ETF (SSK) marks a pivotal moment in the convergence of traditional finance and blockchain innovation.
Scheduled for release on Wednesday, SSK is poised to redefine how investors gain exposure to proof-of-stake cryptocurrencies. Unlike existing crypto ETFs that merely track price performance, this new fund allows shareholders to earn staking rewards — passive income generated by validating transactions on the Solana blockchain.
A New Era for Crypto ETFs
The REX-Osprey Sol + Staking ETF will allocate a portion of its assets toward staking Solana (SOL) tokens, enabling investors to earn yield directly through their brokerage accounts. This represents a significant leap forward in product design, offering both capital appreciation and income generation in a single, regulated vehicle.
With an expense ratio of just 0.75%, SSK is competitively priced compared to other specialized ETFs. Notably, no other U.S.-listed ETF currently holds Solana directly, and even spot Ethereum ETFs — which have gained rapid traction — do not offer staking functionality.

This structural innovation reflects growing institutional confidence in proof-of-stake mechanisms and signals broader acceptance of crypto-native financial primitives within mainstream markets.
Regulatory Hurdles and Strategic Adjustments
The path to approval wasn’t without obstacles. In May, REX Financial and Osprey Funds announced they had cleared initial registration hurdles with the Securities and Exchange Commission (SEC). However, in an unusual move, SEC staff raised objections late in the process.
The central issue revolved around whether the fund qualifies as an "investment company" under the Investment Company Act of 1940 — a classification that requires primary investments in securities. Since many in the crypto industry argue that assets like Solana are not securities, this created regulatory tension.
To address these concerns, the issuer revised its strategy. According to a June 27 prospectus update, the fund will now invest at least 40% of its assets in other ETFs and exchange-traded products — most of which are registered outside the United States. This shift strengthens compliance positioning by anchoring a substantial portion of holdings in traditional securities.
Strahinja Savic, Head of Data and Analytics at FRNT Financial, commented:
“Allowing staking-yield ETFs to list is another step toward integrating public markets with the crypto economy. It shows that the current administration is opening the door for digital assets to become a mainstream part of the U.S. financial system — no longer a niche or inaccessible asset class.”
Shifting Regulatory Winds
Under the leadership of newly appointed SEC Chair Paul Atkins — a known advocate for digital assets — the agency has signaled greater openness to crypto innovation. Internal guidance now suggests that certain tokens, including meme coins and stablecoins, may fall outside the scope of securities regulation.
This evolving stance aligns with broader policy goals, including promoting stablecoin adoption and enhancing U.S. competitiveness in fintech. As Savic notes, introducing staking-based products into public markets supports these objectives by enabling regulated access to blockchain-native yields.
Investors can now participate in dollar-denominated blockchain transactions — such as lending, staking, and yield accrual — through familiar investment vehicles like ETFs, reducing barriers to entry and improving transparency.
The Road Ahead: Opportunities and Uncertainties
Despite the progress, challenges remain. Regulatory frameworks around staking rewards — particularly regarding tax treatment, reporting requirements, and operational risk — are still developing. ETF issuers must demonstrate robust risk management practices to ensure compliance while maintaining performance integrity.
Staking involves technical complexities: node operation, network downtime risks, and potential slashing penalties. These must be carefully managed within a regulated structure designed for traditional assets.
Still, the approval of SSK sets a powerful precedent. It validates the feasibility of yield-generating crypto ETFs and paves the way for similar products tied to other proof-of-stake blockchains like Cardano, Polkadot, or Cosmos.
Nate Geraci, President of The ETF Store, views this as the beginning of a broader trend:
“This unofficially kicks off ‘Crypto ETF Summer.’ I expect a wave of new crypto ETF launches over the coming months. It also hints that staking-enabled spot Ethereum ETFs could be approved sooner than we think.”
Market Momentum Builds
SSK isn’t entering a vacuum. The Volatility Shares Solana ETF (SOLZ), which tracks Solana futures, launched in March and now manages approximately $20 million in assets. Its leveraged counterpart, the Volatility Shares 2X Solana ETF (SOLT), offers double exposure to SOL and has attracted $52 million since inception.
These figures underscore strong investor appetite for Solana-related products — a trend likely to accelerate with the arrival of a yield-bearing option.
