## Flashbots Auction

The Flashbots auction is a private communication channel that allows users to submit transactions directly to block builders, bypassing the public mempool. This mechanism was created to mitigate the negative impacts of MEV, such as sandwich attacks, by providing a way to include transactions without revealing them to the public.

Searchers bid for the right to have their transaction bundles included in a block, creating a more efficient and less toxic environment. It has become the standard for professional traders and arbitrageurs to execute sensitive orders.

It effectively shifts MEV competition from the public mempool to a controlled auction environment.
