The OPinit Bridge is an implementation of the optimistic rollup bridge, implemented as two Cosmos SDK modules; the OPchild Module and the OPhost Module.
The OPchild Module acts as a counter-party to the OPhost Module and is integrated into all Interwoven Rollup implementations. This module is responsible for:
Operator Management: Adding, removing, and managing operators for a given rollup.
Bridge Message Execution: Processing messages received from the Initia L1.
Oracle Updates: Managing oracle price feed updates relayed by the OPinit Executor.
Actions related to both of these two modules are normally handled by the OPinit Bot Executor.
