Morgan Stanley Investment Management launched the Morgan Stanley Ethereum Trust and Morgan Stanley Solana Trust on NYSE Arca, spot exchange-traded products that will stake portions of their holdings, the firm said in a press release published Tuesday.

The launch deepens the first crypto ETP franchise from a major U.S. bank-affiliated asset manager, and the staking feature puts Morgan Stanley ahead of most incumbents on yield: both funds intend to stake a portion of their ether or SOL, and MSIM said it will not keep any of the rewards for itself.

The trusts, trading under MSSE and MSOL, each charge a 0.14% expense ratio and track the CoinDesk Ether and Solana Benchmark 4PM NY Settlement Rates. They follow the Morgan Stanley Bitcoin Trust, which launched earlier this year as the first cryptocurrency ETP from a U.S. bank-affiliated asset manager and held more than $381 million in assets through July 16, according to the release.

"The addition of MSSE and MSOL reflects the natural evolution of our product suite, which seeks to provide simplified access to digital assets through the ETP wrapper," Ally Wallace, global head of ETFs for Morgan Stanley Investment Management, said in the release.
