Jinse Finance reported that crypto asset management company Grayscale is adding staking functionality to its Ethereum and Solana products: Grayscale Ethereum Trust ETF (ETHE), Grayscale Ethereum Mini Trust ETF (ETH), and Grayscale Solana Trust (GSOL). This move makes ETHE and ETH the first spot crypto ETPs listed in the United States to offer staking services, while GSOL also becomes one of the few ways for investors to participate in Solana staking through traditional brokerage accounts. Now, investors can simply deposit these funds into regular brokerage accounts to earn rewards.
