Flashbots

Flashbots is a research and development organization formed to mitigate the negative externalities and existential risks posed by MEV. They aim to Democratize MEV Extraction through MEV-Geth, which enables a sealed-bid block space auction mechanism for communicating transaction order preference.

ELI5 Link:

Flashbots created an ETH node for miners, that not only watches the mempool like any other node, but also connects to a relayer (a server) operated by Flashbots. This MEV-Relay is a kind of parallel channel that directly connects miners to bots that want their transactions included.

The transactions that the bots want to include are sent through the MEV-Relay as bundles containing:

  • the transactions to execute

  • a tip to the miner, coming as an ETH transfer

These transactions use a 0 gwei gas price, as the payment to the miner is included in the transaction itself as the tip.

Since these transactions are sent through a parallel private relay, it reduces the mempool bidding war, failed transactions bloating the blockchain, and overall gas cost for users.
