Also +1 for EIP-7002: Execution layer triggerable exits for the benefit of non-custodial staking services.
The ability for users to exit of their own accord, without action from their staking provider, is critical for staking services to remain non-custodial in the eyes of regulators. It’s possible with VoluntaryExit messages, but it’s very awkward and requires exchange of a “secret message” between the user and the staking service. With EIP-7002 the entire interaction can take place publicly on-chain.
EIP-7002 would put the last necessary piece in place for simple and elegant non-custodial staking offerings. While complex liquid staking offerings are clearly appealing, I think there’s also space for ultra-simple, non-liquid, delegated staking directly between node operators and ETH holders. They could offer lower fees due to lower overheads and be attractive to whales looking for a “fixed-term deposit” rather than high liquidity.
