Techub News, citing Crypto Briefing, reported that Morgan Stanley has filed a second amended S-1 registration statement with the U.S. Securities and Exchange Commission for two proposed crypto trust products: the Ethereum Trust, known as MSSE, and the Solana Trust, known as MSOL. The updated filing provides further details on the structure of the two spot crypto asset trusts, including fee levels and staking-related arrangements.
MSSE and MSOL Set Annual Fees at 0.14%
According to the amended filing, both the Ethereum Trust and the Solana Trust would charge an annual fee of 0.14%. The report states that this fee level is lower than competing products from Grayscale and Franklin Templeton. The documents also disclose that the two funds would retain 95% of staking rewards within the trusts, a structure intended to directly benefit shareholders of the respective products.
Morgan Stanley first filed applications in January for Bitcoin, Ethereum and Solana trust products. Its Bitcoin Trust, MSBT, was listed on NYSE Arca on April 8. The latest second amended S-1 registration statement focuses on the Ethereum and Solana trusts, following the listing of the Bitcoin trust earlier this year.
Staking Infrastructure Providers Named in the Filing
The amended documents identify Figment, Galaxy Blockchain Infrastructure and Coinbase Canada as staking infrastructure providers. This disclosure is tied to the staking component of the proposed trusts, including the arrangement under which 95% of staking rewards would remain inside the trust structure for shareholders.
As of the report, the SEC has not approved a specific listing date for either the Ethereum Trust or the Solana Trust. The products remain at the amended registration statement stage, with any listing timetable dependent on regulatory approval and the related exchange process.
