*Urgent* [Cronos] - Upgrade to v1.7.7

Scheduled for Jun 24, 05:30 - 07:30 UTC

Scheduled

Blockdaemon will update all Cronos Mainnet nodes to v1.7.7 on 06/24/2026 at 05:30 UTC. We are updating our nodes due to a release from the Cronos Foundation. This update applies to all Blockdaemon Cronos mainnet nodes.

Note: We will be upgrading the nodes using base version v5.0.2. This requires a manual kernel upgrade and a node reboot before the application upgrade can proceed. As a result, downtime may be up to 30 minutes per node.

If you have any questions or concerns, please reach out to your Customer Success Manager.
