BlackRock has officially launched its Ethereum staking ETF, named ETHB, to cater to the growing demand for cryptocurrency fund yields. The ETF's fee is set at 0.25% basis points, similar to ETHA, but offers a reduced fee of 0.12% for the first year or the first $2.5 billion in assets. The fund not only tracks Ethereum's market price movements but also provides staking yields to investors by staking its held ETH on-chain.
