Blockdaemon will update Polygon Mainnet nodes to bor v2.8.0 on 05/20/2026 at 10:00 UTC. We are updating our nodes due to a release from the Polygon foundation, in preparation for the Chicago Hardfork on 05/21/2026. This update applies to all Blockdaemon Polygon Mainnet nodes. There will be planned downtime of up to 5 minutes per node.

We have tested the release and do not anticipate any unexpected downtime other than mentioned above as a result of the update. If you have any questions or concerns please reach out to your Customer Success Manager.
