questions about the MEV rpc.

I have several questions about the MEV rpc.

  1. Are bundles submitted to the RPC endpoint only for Manifold block builder ? Are bundles shared with any third party block builders (vetted by Manifold ) ?

  2. Does Manifold block builder send built block to relays besides Manifold relay ?

Asking because website mentioned “SecureRPC provides an aggregated connection to endpoints like Flashbots, Eden Network, etc.”

  1. Do we implement a high / low priority queue system for bundle forwarding similar to flashbots (IE: I need a private key to identify my reputation in order to qualify for high priority queue )
