BlackRock's Ethereum Staking ETF charges an 18% commission on staking rewards. Several experts have evaluated the costs and risks, summarizing that BlackRock's iShares Staked Ethereum Trust launched in March with a management fee of 0.25% and an 18% staking reward commission. Industry insiders believe this commission includes multiple costs and may decrease in the future. Some question whether such high fees are reasonable, especially when compared to retail staking rates. According to Gate News, on April 8, BlackRock's iShares Staked Ethereum Trust (ticker ETHB) was launched on March 12, with a management fee of 0.25% (temporarily reduced to 0.12%), and an 18% commission on the total staking rewards of approximately $318 million worth of ETH within the trust, split between BlackRock and a certain CEX. Based on the current ETH staking yield of about 2.74%, the 18% commission roughly equates to a total return of 49 basis points. Falconedge CEO Roy Kashi believes this 18% covers costs such as custody, penalty risk, validator fees, and brand premium, estimating the operational cost floor of staking ETFs at around 5%. Richard Shorten, founder of GlobalStake, points out that there are still many hidden costs before the rewards reach the ETF. Ethan Buchman, co-founder of Cosmos, states that 18% is not unreasonable for institutional products but expects it to be compressed to 15% or even 10% in the future. Harriet Browning, Vice President of Sales at Twinstake, warns that excessive fee competition could lead some providers to lower standards in security and transparency. Currently, this commission is still lower than the maximum 25% fee paid by retail investors for direct ETH staking on mainstream crypto platforms. Financial advisor Tyrone Ross questions whether it is worth surrendering 18% of staking rewards to BlackRock and a certain CEX.
