21Shares US LLC has introduced Ethereum staking for its 21Shares Ethereum ETF (TETH) and announced a 12-month waiver of management fees, effective October 9th. During this period, the total expense ratio of 0.21% will be waived. The ETF will continue to track the CME CF Ether-Dollar Reference Rate and include staking rewards. 21Shares will stake a portion of its ETH holdings to participate in network validation and generate returns. The company also manages the ARK 21Shares Bitcoin ETF, with assets under management exceeding $5.5 billion. TETH is not registered under the 1940 Act, indicating a higher investment risk.
