OP Sepolia: Batcher degraded performance

    Resolved

    The safe head has now resumed normal operation.

  • Monitoring
    Monitoring

    We have identified and applied a potential fix for the batcher performance issue. We will continue to monitor the situation.

  • Investigating
    Investigating

    Due to heightened L2 block size on OP Sepolia, the batcher is seeing some performance degradation. This is causing the safe head to progress more slowly than usual. We are currently investigating.

    We have performed the switch back to calldata. Users should observe a more stable safe head, as well as lower fees. We will switch back to blobs once the L1 congestion subsides.

  • Identified
    Identified

    We are currently experiencing elevated fees on OP Mainnet due to high blob fees on L1. We are mitigating the issue by switching batch submission back to calldata.

    While the switch rolls out, users may experience higher fees than normal and the safe head may increase less often due to L1 congestion.
