Is there a good RPC provider that's a drop in replacement for Infura but for private txs?

flashbots! https://x.com/bertcmiller/status/1704171687283966412?s=46

but also, it’s built right into Rainbow 🤗 you can toggle on/off flashbots in our swap flow

users can also set the slippage low, because they don't have to worry about paying fees for failed transactions!
