It is the first U.S.-listed crypto staking exchange-traded fund.
REX Shares and Osprey Funds have selected Anchorage Digital as the exclusive custodian and staking partner for their newly launched REX-Osprey Solana + Staking ETF (SSK), the first crypto staking exchange-traded fund (ETF) listed in the U.S.
The fund, which offers investors exposure to Solana
Unlike existing spot bitcoin and ethereum ETFs, which fall under different regulatory frameworks, SSK is registered under the Investment Company Act of 1940. That means a qualified custodian — not the fund issuer — is required to hold the underlying assets. Anchorage Digital, currently the only federally regulated bank authorized to both custody and stake digital assets, will fill that role.
“Staking is the next chapter in the crypto ETF story,” said Nathan McCauley, CEO and co-founder of Anchorage Digital, in a release. “The launch of crypto staking ETFs marks a win for consumers and a significant step forward in full access to the crypto ecosystem.”
The ETF gives investors indirect exposure to Solana while also participating in the blockchain’s staking mechanism, which provides additional yield by helping to secure the network. Staking allows holders of certain cryptocurrencies to earn rewards by locking their tokens into the network, a process that previously required technical know-how and direct interaction with crypto protocols.
By packaging staking into an ETF structure, REX Shares and Osprey aim to make that process accessible to a wider range of investors through traditional brokerage accounts.
The SSK launch comes as the crypto ETF market continues to evolve beyond bitcoin and ether, with issuers exploring new ways to bring blockchain-based products to regulated exchanges. The introduction of staking ETFs marks a new phase for the industry, combining income-generating features with exposure to digital assets, all within an SEC-regulated investment vehicle.
