Scheduled

Blockdaemon will update all Polygon Mainnet nodes to Erigon v3.3.6 and Bor v2.5.6 on January 08, 2026 at 10:00 UTC.
We are updating our nodes due to the official release for Polygon. There may be planned downtime of up to ten minutes.

Customer Impact
During the upgrade window, Polygon-based services hosted by Blockdaemon may be temporarily unavailable for up to ten minutes while nodes are restarted and updated. Customers may experience temporary errors, failed or delayed transaction submissions, and intermittent issues when querying Polygon network data until the upgrade is complete.

Additional Information
Blockdaemon has validated this release and does not anticipate unexpected disruptions beyond any stated downtime.
