BlackRock's staking Ethereum ETF attracted approximately $46 million in funding within two days of its launch, holding spot ETH and staking 70%-95% of ETH through CEX. Investors can receive approximately 82% of staking rewards monthly, with remaining rewards going to BlackRock and service providers. The fund's non-compounding design attracts large investors, and BlackRock chose to launch the staking ETF independently to mitigate risks.
