Lido resolved a minor incident during the stETH rebase on July 26 after a reporting oracle accidentally omitted a single 32 ETH validator deposit from its calculations. This caused the protocol to report a daily annualized rate of 2.04% instead of the expected 2.15%, before the corrected figure rebounded to 2.29%. No funds were at risk and no user action was required. Lido’s built-in guardrails, designed to tolerate fluctuations up to 3.6% of Total Value Locked over a 36-day period, absorbed the deviation without triggering an emergency. An updated version of the oracle was deployed and audited on the same day, with a full root-cause analysis still in progress.
