The first U.S. exchange-traded fund offering exposure to Solana and on-chain staking rewards began trading this week, drawing significant investor interest. The product provides a regulated pathway for investors to gain access to Solana’s price performance while earning passive staking rewards.
On July 2, 2025, the REX-Osprey Solana + Staking ETF, trading under the ticker SSK, was listed on the Cboe exchange. The ETF concluded its first trading day with approximately $33 million in volume and $12 million in inflows, according to market data.
This initial performance exceeded the early results of Solana and XRP futures ETFs but did not reach the record-breaking volumes seen in Bitcoin and Ethereum spot ETFs earlier in the year.
How the Solana Staking ETF Works
SSK is structured in compliance with the Investment Company Act of 1940, a regulatory framework that enforces strict investor protection and custody standards. Anchorage Digital, a federally chartered cryptocurrency bank, serves as the custodian and staking partner for the fund.
The ETF is designed to track Solana's market price while generating additional yield through staking. Investors receive monthly cash payouts derived from staking rewards. Approximately 80% of the fund's assets are allocated to SOL, with at least half of that amount staked via institutional validators such as Galaxy and Figment.
The remainder of the portfolio consists of liquid staking tokens like JitoSOL and other Solana-related exchange-traded products listed in international markets such as Canada and Europe. Unlike futures-based products, SSK uses a spot pricing model based on the CME CF Solana-Dollar Reference Rate, which allows it to closely mirror SOL’s actual market value.
Regulatory Background and Market Implications
The launch followed months of review and discussions with the U.S. Securities and Exchange Commission. The regulatory body had initially raised questions regarding fund classification and staking mechanisms. By late June, however, the SEC issued no further objections, effectively allowing the ETF to proceed.
This development arrives amid growing interest in cryptocurrency-based investment vehicles that offer yield-generating mechanisms. With nine additional Solana ETF applications currently under regulatory review, SSK’s market entry may influence how future staking-enabled products are structured and approved.

Frequently Asked Questions
What is a staking ETF?
A staking ETF is an exchange-traded fund that invests in a proof-of-stake cryptocurrency and participates in network validation to earn rewards. These rewards are distributed to investors as income, complementing potential gains from asset appreciation.
How does SSK generate yield?
The ETF stakes a significant portion of its Solana holdings through trusted institutional validators. The staking rewards are converted into cash and paid out to shareholders on a monthly basis.
Is the Solana ETF available to international investors?
While the SSK ETF is listed on a U.S. exchange, international investors should consult local regulations regarding access to U.S.-listed financial products. Other Solana ETPs are available in markets like Canada and Europe.
What are the risks associated with a staking ETF?
Risks include market volatility, regulatory changes, staking slashing penalties, and technological risks related to blockchain network performance. Always conduct thorough research or consult a financial advisor before investing.
How does this differ from holding SOL directly?
The ETF offers a regulated, custodial approach to staking without requiring investors to manage private keys or run validator nodes. It simplifies the process but may involve management fees not applicable to direct holdings.
Will more staking ETFs be launched?
Given multiple pending applications and growing institutional interest, it is likely that more staking-based cryptocurrency ETFs will emerge, potentially including other proof-of-stake assets.
