Polygon Mainnet Heimdall V2 Migration
The maintenance is now complete. Thanks for your patience.
There is a network wide outage, due to bad block errors in the Bor client. The Polygon team is diagnosing it and we are awaiting their instructions.
The scheduled maintenance is now underway. We'll keep you updated on our progress.
Polygon will be conducting a major version upgrade of Heimdall (the consensus layer of Polygon) on the Polygon mainnet on the following dates:
Mainnet: 2025/07/10 14:00 - 17:00 UTC
You can find the official Polygon announcement regarding this migration here.
Bor (the execution client) is expected to remain available as this migration is intended to only affect Heimdall. There is a substantial probability of degraded usability of the Polygon network during the upgrade window.
