REX-Osprey™, a strategic collaboration between REX Shares and Osprey Funds, announced the launch of SSK, the REX-Osprey ™ Solana + Staking ETF, the first U.S.-listed ETF to give investors exposure to Solana (SOL) plus staking rewards in their securities brokerage accounts.

SSK provides investors with cost-effective and convenient exposure to Solana (SOL) by offering primarily spot SOL exposure—avoiding the negative effects of contango that can impact futures-based ETFs. In addition to this direct exposure, the fund also delivers the benefits of SOL staking, which currently offers a reward rate of 7.3%. The fund seeks to hold the majority of its assets in directly staked SOL, 40% of its assets in exchange-traded products that themselves stake SOL, and a small amount of its assets in liquid staking tokens like JitoSOL.) Importantly, all staking rewards received by the fund are passed directly to investors, with neither REX nor Osprey retaining any portion.

An investment in the Fund is not a direct investment in Solana. Investing involves significant risk, including the possible loss of principal.

“This is a major milestone for ETFs and the crypto industry, and a pioneering expansion in how securities investors can access crypto investments and blockchain-native returns,” said Greg King, CEO of REX Financial. “With SSK, we’re giving investors Solana staking rewards in a familiar ETF format—something that’s never been done before in the U.S. market. We’ve essentially built a bridge between the world of TradFi securities investments and the world of crypto investments.”

SSK is designed to serve both retail and institutional investors. Unlike other crypto products that rely on derivatives or just provide spot crypto exposure, SSK participates directly in native Solana staking, ensuring that rewards are sourced from the blockchain protocol itself, and SSK also participates indirectly in staking by holding exchange-traded products that themselves hold staked SOL. This allows investors to take part in Solana’s network economics while maintaining the convenience and transparency of an ETF.

Volume in $SSK now at $20m, which is really strong, top 1% for a new launch. For context, $SOLZ did $1m on Day One, and that's pretty good. Also, the $25m in seed assets makes $SSK already bigger than $SOLZ. https://t.co/ibiKxizeeQ
