The move follows the bank’s successful Bitcoin ETF launch in April, which has since attracted $300.7 million in cumulative net inflows as of June 18.
Lowest Fees in the Market
Both the Morgan Stanley Ethereum Trust and the Morgan Stanley Solana Trust will charge a sponsor fee of 0.14% per year. That fee is calculated daily and paid monthly from each fund’s net asset value.
The 0.14% rate is the lowest currently offered in both categories. Grayscale’s Mini Ethereum Trust currently charges 0.15%, and Franklin Templeton’s Solana ETF charges 0.19%. Morgan Stanley’s Bitcoin ETF also launched at 0.14%, undercutting rivals.
The Ethereum ETF will trade under the ticker MSSE and the Solana ETF under MSOL.
How Staking Works in These Funds
Both funds plan to stake a portion of their crypto holdings to earn additional rewards for investors.
For the Ethereum fund, custodians will place ETH into staking smart contracts. Staking service providers will then run validators on behalf of the trust. Figment Inc., Galaxy Blockchain Infrastructure, and Coinbase Canada will serve as staking service providers for both funds.
Staking service providers and custodians will collectively receive 5% of all staking rewards. The remaining 95% stays inside the fund, benefiting investors. The sponsor will not receive any share of staking income beyond the standard management fee.
The Ethereum filing notes that staked ETH carries slashing risk. This means ETH can be removed from a validator’s account if network rules are broken or a validator fails to perform.
As of May 18, 2026, around 3.64 million ETH was waiting to be activated on validators. Ethereum limits new validators to 56 per epoch, which works out to roughly 57,600 ETH per day. That creates an estimated wait of about 63 days before newly staked ETH starts earning rewards.
The Solana filing uses a similar staking structure but did not disclose a maximum daily staking limit. Staking custodians for the Solana fund will not hold the private keys to any staked SOL tokens.
Where Things Stand
The filing of additional amendments usually reflects active back-and-forth with the SEC staff and is a sign the process is moving forward.
Morgan Stanley is also being watched for a possible XRP ETF application. The bank recently disclosed it holds a stake in existing XRP ETFs, which has fueled speculation it may file next.
The SEC recently approved BlackRock’s Bitcoin Premium Income ETF, which launched on June 16.
