Grayscale has announced that its Ethereum Mini Trust ETF (Ticker: $ETH) and Ethereum Trust ETF (Ticker: $ETHE) are now the first U.S.-listed spot crypto exchange-traded products (ETPs) to offer staking. This development marks a significant milestone for Grayscale as it continues to innovate in the crypto investment space. Additionally, Grayscale's Solana Trust (OTCQX: $GSOL) has also enabled staking. The firm is awaiting regulatory approval for GSOL's uplisting to an ETP, which would make it one of the first spot Solana ETPs to offer staking capabilities.
