Nodit is aware of recent data consistency issues following the Heimdall-v2 client upgrade(7/11) on the Polygon network, which led to the detection of multiple unexpected large reorgs.

Our team is currently reviewing and correcting portions of data in the Nodit Data API that were indexed prior to the reorgs. These anomalies originate from events outside of the expected network specification.

We are in the process of confirming the exact scope (affected block ranges) and details of the impact. Updates will be provided once our review is complete. In the meantime, please take this advisory into account when using Polygon mainnet data.

For reference, see an example of the July 30 reorg on PolygonScan:
PolygonScan – Forked Blocks Example

We appreciate your understanding as we work to ensure accurate and reliable data across all supported networks.
