Developers have emphasized that stakers were not affected and the protocol remains fully operational—the oracle system requires the agreement of five out of nine nodes, and the incident involved only one of them.

Lido and the oracle operator Chorus One are conducting an investigation. According to a preliminary report, the key was compromised on May 10, and the corresponding ETH balance was stolen.

The team suggests that the issue is not the result of a broader infrastructure hack. Rather, the hot wallet key was leaked online as part of a previous data breach.

At the time of writing, the vote has already commenced. The main phase will last 72 hours, followed by a 48-hour objection phase.

Earlier, Lido developers announced an update allowing stETH holders to delay and block DAO decisions.
