Morgan Stanley Investment Management is expanding beyond Bitcoin with the launch of Ethereum and Solana exchange-traded products that will generate staking rewards for investors, the latest step in the Wall Street firm's growing push into digital assets. Announced on Tuesday, the Morgan Stanley Ethereum Trust (NYSE Arca: MSSE) and Morgan Stanley Solana Trust (NYSE Arca: MSOL) will track the price of Ethereum and Solana, respectively. The launch is the latest crypto initiative that Morgan Stanley has announced this year. "We're not going to stop at just Bitcoin," Amy Oldenburg, head of digital-asset strategy at Morgan Stanley, previously told Decrypt. In July, Morgan Stanley rolled out spot Bitcoin, Ethereum, and Solana trading for eligible E*TRADE customers through a partnership with Zero Hash, allowing clients to buy, sell, and hold digital assets alongside stocks and other investments.
