Following the Ethereum Foundation's announcement regarding the Pectra Hardfork, we plan to upgrade our Ethereum clients.

For more details on the Ethereum upgrade, you can review the tag release:
https://github.com/ethereum/go-ethereum/releases/tag/v1.15.3
https://github.com/erigontech/erigon/releases/tag/v2.61.2
https://github.com/sigp/lighthouse/releases/tag/v7.0.0-beta.1

As some L2 networks, such as Optimism Sepolia and Base Sepolia, rely on Ethereum for security and data availability, this hardfork also requires corresponding updates for these networks.

For more details on L2 chain upgrades, you can review the tag release:
https://github.com/ethereum-optimism/optimism/releases/tag/op-node%2Fv1.11.1
https://github.com/ethereum-optimism/op-geth/releases/tag/v1.101500.0

During the upgrade process, please note that there will be no network downtime, however some network interruptions may occur.

If you have any concerns, questions, or need to discuss how this might impact your project specifically, please don't hesitate to reach out our support at nodit@lambda256.io

Thanks you for your patience and continued trust in our services.
