Lido Addresses stETH Rebase Discrepancy, Ensures Fund Safety
On July 26th, the Ethereum staking protocol Lido confirmed the successful correction of a calculation discrepancy that affected the previous day's stETH reward distribution (rebase). The technical operation proceeded as planned, restoring the ETH staking rewards that were initially missed due to an under-calculation.
Resolution and System Enhancement
Alongside the reward correction, Lido updated its core protocol oracles, which have passed relevant audits. This new version is expected to deliver key improvements:
- Increased reporting speed for better system responsiveness.
- Enhanced diagnostic capabilities to faster pinpoint the causes of similar issues in the future.
Throughout the incident, Lido reiterated that user staked funds and rewards were never at risk, with all operations conducted within the protocol's security parameters.
Ongoing Root Cause Investigation
The engineering team at Lido continues to investigate the exact cause of yesterday's calculation anomaly. Preliminary analysis suggests the issue may have stemmed from a specific edge case: the system inadvertently excluded a validator node that was in a "pending deposit" state during the calculation cycle, causing a portion of the staking rewards generated by that node to be omitted.
Lido has committed to publishing a comprehensive post-mortem report in the coming days. This document will provide details on:
- The technical root cause of the issue.
- The immediate corrective actions taken by the team.
- Long-term protocol improvements to prevent recurrence.
The team pledges to maintain transparency and keep the community updated as the investigation progresses.
