Network Data Metrics Recalculation
Identified - We have identified the root cause of the issue and are working on a fix. Updates will be shared as they are available.
Oct 08, 2025 - 10:28 UTC
Investigating - We are currently aware of data quality issues affecting the USDC ticker. Specifically, the metric AdrActCnt (Active Addresses Count) is incorrect for the time range prior to May 2025.
Our engineering team is investigating the source of this issue and working on a fix. Once this fix is released, we will correct the affected metrics and backfill with the correct values.
We will provide updates on this effort here as they become available.
