My friend suddenly gave me an idea. If the staking of a spot ETF is approved, there will definitely be no certificates given. So, if I issue an etETH, each etETH corresponds to a share of my stock ETF, such as BlackRock's ETHA. When the ETHA generates interest, all the profits will be distributed to all etETH holders, which can be considered as DeFi or RWAFi Of course, doing an audit is also one thing. Because essentially this is a centralized behavior, it is difficult to verify through decentralized methods and cannot be executed through smart contracts, but it is indeed interesting and I believe there will be such a space in the future.
