BlackRock's iShares Staked Ethereum Trust (ETHB) launched on March 12 and surpassed $254 million in assets under management within one week, including over $100 million in seed funding with approximately $146 million in subsequent inflows. The fund will stake 70%–95% of its holdings and distribute 82% of staking rewards to investors monthly, with a management fee of 0.25% (reduced to 0.12% for the first $2.5 billion in assets under management in the first year). This represents an important signal of continued institutional capital inflows into Ethereum.
