  1. I-01 Informational Configuration Can Delay Bridges Warning Acknowledged
    Location
    Global

    Description

    The configuration to lower the confirmations from 1,000 to 500 on Rootstock will temporarily create a Block Confirmation Mismatch as described in the LayerZero Documentation here.

    If bridges from Rootstock to any chain are made after the Rootstock configuration has been updated from 1,000 block confirmations to 500 block confirmations on Rootstock, but before the receiving confirmations have been updated on the target chain it will result in this block confirmation mismatch and these messages will be blocked until the configuration goes through and some bridge executions may need to be retried through the permissionless EndpointV2 lzReceive function.

    Recommendation

    Be aware of this risk for any messages that are in-flight during the time of configuration, and try to make configurations across all chains within a short period.
