In addition to point-to-point communication utilized in State Registry contracts, Superform contracts also utilize broadcasting to support communication from one chain to all chains Superform contracts are deployed on. BroadcastAmbImplementation is used as an abstract contract that all AMBs used for broadcasting must implement.

Superform uses this to setup addresses and roles across chains and as a circuit breaker measure to switch the protocol into a gated withdraw-only mode.
