Oleksii Trofimchuk sued Lido Finance and Stakefish on September 8 in Santa Clara County Superior Court after his wallet was compromised and competing MEV (maximal extractable value) bots used high-priority-fee transactions to claim the associated ETH. Chun Wang, F2Pool co-founder and Stakefish founder, said Stakefish, acting as a validator, must package legitimate transactions under Ethereum protocol rules and cannot adjudicate off-chain ownership disputes. He warned that requiring validators to recover rewards based on off-chain claims would create legal uncertainty for staking rewards and harm Ethereum’s decentralization and credible neutrality.
