Solana Staking ETF Launches in U.S., Offering TradFi Access to On-Chain Yields

A new ETF offering exposure to Solana (SOL) and its staking rewards made its U.S. market debut this week. The product, named SSK, comes from REX-Osprey™, a joint venture between REX Shares and Osprey Funds.

This marks the first U.S.-listed ETF to offer Solana staking exposure in a traditional brokerage account.

Direct SOL Exposure, Staking Rewards in an ETF Wrapper

SSK aims to provide investors with exposure to Solana while also passing along staking yields. The fund holds the majority of its assets in directly staked SOL. It also holds exchange-traded products that stake SOL and a small allocation to liquid staking tokens like JitoSOL.

At current network rates, staking rewards on Solana sit at approximately 7.3%. All rewards earned by the fund are distributed entirely to shareholders. Neither REX nor Osprey retains a cut of the staking yield.

This structure gives investors exposure to Solana’s native economics—without needing to manage private keys, operate validators, or leave traditional finance infrastructure.

The ETF drew immediate attention. It logged $9 million in volume in its first 30 minutes, closing the day at $33 million. That performance outpaced SOL and XRP futures ETFs, though it still trailed BTC and ETH spot ETFs.

The launch of SSK may signal growing institutional interest in staking-based returns—especially for altcoins. By combining staking and spot exposure into a compliant vehicle, the ETF lowers the barrier for funds, institutions, and retirement accounts to access the Solana ecosystem.

TradFi-Friendly Access to On-Chain Yield

SSK is structured to fit into existing financial systems. Investors can access the ETF through retirement plans, brokers, and institutional platforms. While it doesn’t represent direct ownership of SOL, it mimics its exposure and yield within a regulated structure.

Greg King, CEO of REX, called it a “bridge between TradFi and crypto,” emphasizing that the product is not just about Solana, but about unlocking the broader altcoin market.

SSK also avoids futures-based exposure and its risks, such as contango. Instead, it tracks SOL more directly, aiming for efficient and cost-effective access to staking rewards.

Implications for the Crypto ETF Landscape

The launch of SSK comes as infrastructure continues to evolve around crypto investing. Institutional players often require regulated wrappers before entering emerging sectors. SSK may set a precedent for other staking-based ETFs tied to altcoins.

For Solana, the ETF provides another layer of legitimacy. It moves SOL into portfolios that traditionally avoid direct crypto exposure—pension funds, institutional mandates, and passive retail investors.

As more projects explore ETF formats with staking components, the SSK debut may mark a shift in how blockchain rewards are packaged and accessed by the mainstream financial world.
