BlackRock has filed for a staked Ethereum (ETH) exchange-traded fund (ETF) that could allow the asset manager to retain up to 18% of staking rewards as fees. This filing marks a significant move in the crypto ETF space, as BlackRock continues to expand its offerings in digital assets. The proposed ETF would provide investors with exposure to staked ETH, while BlackRock would manage the staking process and collect a portion of the rewards as compensation.
