Prepare for Fjord Breaking Changes

The Fjord upgrade for Boba Sepolia was activated on 1722297600 Tue July 30 00:00:00 UTC 2024. The Fjord Boba Mainnet upgrade will be optimistically activated 1725951600 Tue Sep 10 7:00:00 UTC 2024.

For Node Operators

Node operators are required to upgrade to Fjord before the activation date to avoid chain divergence. For Boba Mainnet, the op-node release v1.6.8 and the op-erigon release v1.2.0 contain these changes.

Update to the Lastest Release

Configure the Fjord Activation Date

For op-node and op-erigon, the Fjord activation date is included in the release, so no action is needed by the operators to configure the node.

For op-geth, the node operator is required to add --override.fjord=1725951600 to set up the Fjord hardfork.

Verify Your Configuration

Make the following checks to verify that your node is properly configured.

  • op-node , op-erigon and op-geth will log their configurations at startup

  • Check that the Fjord time is set to activation-timestamp in the op-node startup logs

  • Check that the Fjord time is set to activation-timestamp in the op-erigon startup logs

  • Check that the Fjord time is set to activation-timestamp in the op-geth startup logs
