Several asset managers, including BlackRock, Fidelity, and Grayscale, have submitted their final documents to launch exchange-traded funds (ETFs) tied to Ethereum's ether (ETH). The applications are expected to be approved by the US Securities and Exchange Commission (SEC) on Monday, with trading to begin on Tuesday. The filings reveal the final details of the fund structures, including management fees, which are expected to be similar to the fee war seen in the launch of spot bitcoin ETFs earlier this year. Grayscale's decision to charge a significantly higher fee of 2.5% on its main product than others has been questioned by industry commentators.
