This development comes on the heels of the firm’s Bitcoin ETF debut in April, a product that has garnered $300.7 million in total net inflows through June 18.
Industry-Leading Low Fee Structure
The Morgan Stanley Ethereum Trust and Morgan Stanley Solana Trust will each impose an annual sponsor fee of just 0.14%. This expense ratio is computed on a daily basis and deducted monthly from the fund’s net asset value.
At 0.14%, these products beat all current market alternatives. Grayscale’s Mini Ethereum Trust carries a 0.15% fee, while Franklin Templeton’s Solana ETF charges 0.19%. Morgan Stanley previously used the same 0.14% pricing strategy with its Bitcoin ETF, positioning itself below competitors.
Trading symbols have been designated as MSSE for the Ethereum product and MSOL for the Solana offering.
Staking Mechanism Explained
Each fund intends to stake some of its digital asset holdings to generate supplementary returns for shareholders.
In the Ethereum product, custodians will deposit ETH into staking smart contracts. Designated staking service providers will then operate validators for the trust. Three entities—Figment Inc., Galaxy Blockchain Infrastructure, and Coinbase Canada—will handle staking services for both funds.
Service providers and custodians will together claim 5% of total staking rewards. The other 95% remains within the fund for investor benefit. The sponsor will not collect any portion of staking income apart from its regular management fee.
The Ethereum documentation acknowledges slashing risk associated with staked ETH. This mechanism allows ETH to be deducted from a validator’s balance if protocol rules are violated or if the validator underperforms.
According to May 18, 2026 data, approximately 3.64 million ETH was queued for validator activation. Ethereum’s protocol restricts new validator activations to 56 per epoch, translating to about 57,600 ETH daily. This constraint produces an estimated waiting period of roughly 63 days before freshly staked ETH begins generating rewards.
The Solana documentation employs a comparable staking framework but didn’t specify a maximum daily staking threshold. Staking custodians for the Solana product will not possess private keys to any staked SOL tokens.
Current Status and Outlook
The submission of further amendments typically indicates ongoing dialogue with SEC personnel and suggests the approval process is progressing.
Market observers are also monitoring Morgan Stanley for a potential XRP ETF filing. The institution recently revealed holdings in existing XRP ETFs, sparking speculation about a forthcoming application.
The SEC recently greenlit BlackRock’s Bitcoin Premium Income ETF, which began trading on June 16.
