+#### rpc-based "payment for order flow protocols" (POFPs) + * this type of private order flows can be realized by modifying either the user's rpc or by modifying the protocol's frontend * the rpc endpoint re-broadcasts (forwarding) the tx to nodes. * in respect to every pending tx they receive, they can: 1) censor, 2) forward to some mempool, or 3) forward it directly to some block-builders or validators.
