MEV (Maximal Extractable Value) is profit from reordering, inserting, or censoring transactions inside blocks.
Public mempools expose your intent, enabling frontrunning and sandwiching.
With MEV-protected RPC / private orderflow, transactions are sent privately to relays and block builders
instead of being broadcast to the public mempool. Builders simulate and bundle the orderflow for inclusion, so sensitive
intent (large swaps, arbitrage) isn’t visible to predatory bots before it lands on-chain.
After the trade is included in a block, it becomes fully verifiable on-chain like any other transaction.
Until inclusion, it stays out of the public mempool. (Optional fallbacks can broadcast publicly if private inclusion fails.)
A sandwich attack surrounds your trade with two attacker trades: a buy just before you (pushes price up) and a sell right after you,
capturing profit and leaving you with worse execution.
Private orderflow prevents your pending trade from being visible in the public mempool, removing the attacker’s window to
set up the sandwich.
