BlackRock's iShares has filed an amended S-1 with the SEC to launch the "iShares Staked Ethereum Trust ETF" (ticker: ETHB) on Nasdaq. The trust will primarily hold Ethereum (ETH) and plans to stake approximately 70%–95% of its assets through third-party nodes like Coinbase to earn staking rewards, without affecting the trust's tax status. The ETF will use a 40,000-share basket creation and redemption mechanism, allowing for cash or physical ETH transactions, limited to authorized participants. The annual base fee is set at 0.25%, with a reduced rate of 0.12% for the first $2.5 billion in assets during the initial 12 months. The trust aims to continue issuing shares under controlled risk conditions.
