Grayscale Investments has introduced staking capabilities to its Ethereum (ETH) and Solana (SOL) investment products. This new feature is now available in Grayscale's Ethereum-based exchange-traded funds (ETFs), including the Grayscale Ethereum Trust (ETHE) and Grayscale Ethereum Mini Trust (ETH). Additionally, Grayscale plans to convert its existing Grayscale Solana Trust (GSOL) into an ETF with staking options, enabling investors to earn staking rewards through traditional brokerage accounts. This strategic move aims to enhance the appeal of these altcoin ETFs compared to Bitcoin-based ETFs, especially if the prices of ETH and SOL remain stable.
