Rex Shares and Osprey Funds' innovative SOL staking-enabled ETF (SSK) has made a strong debut. On its first day of trading on the Chicago Board Options Exchange (CBOE), the ETF attracted a substantial $12 million inflow, signaling robust investor interest in Solana-based investment products. Trading volume for SSK reached an impressive $33.6 million. This launch marks a significant milestone as SSK is the first cryptocurrency ETF in the US that actively supports staking. Staking allows investors to earn rewards on their SOL holdings, potentially enhancing returns beyond simple price appreciation. This novel feature likely contributed to the ETF's initial success and sets a new precedent for future crypto investment vehicles in the US market. The ETF offers investors exposure to Solana (SOL) while simultaneously benefiting from staking rewards. ```
