[Op-Stacks] - Upgrade to OP-stack v1.18.0

Scheduled for May 18, 07:00 - 08:00 UTC

Scheduled

Blockdaemon will update OP-stack (Optimism, Ink and Unichain) testnet and mainnet nodes to OP-stack v1.18.0 on 05/18/2026. We are updating our nodes due to a release from the Optimism foundation. This update applies to all Blockdaemon OP-stack testnet and mainnet nodes; there will be planned downtime of up to 15 minutes per node within a 1-hour maintenance window.

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.
