# What, Why, How?

## WTF is SuiFlow?

Think of it as [MevBlocker](https://cow.fi/mev-blocker) for Sui. 

MEV bots exploit arbitrage opportunities to siphon millions of dollars daily from trades, without compensating the users who create these opportunities. SuiFlow aims to change this by providing MEV bots with faster order flow, while requiring them to share the profits with the users who enabled the arbitrage.

## How Does SuiFlow Work?

SuiFlow can be seamlessly integrated as an RPC. Users simply add the SuiFlow RPC to their wallet, and it's ready to go—no additional setup required.

### Technical Details

**Making Transaction Faster**

The SuiFlow team operates 20+ nodes strategically placed near top validators, enabling significantly faster transaction certificate assembly and broadcasting—up to 400ms quicker than the default RPC. This ensures a superior speed advantage for users.

### Facilitating MEV

SuiFlow identifies potential order flow and sends relevant transactions to MEV searchers before they reach any validators. The searchers then generate backrun transactions with refunds and return them to SuiFlow. SuiFlow selects the backrun transactions with the highest refunds and sends both the original and backrun transactions to validators, ensuring they are included in the same checkpoint. Without SuiFlow, MEV bots would have to wait for at least two checkpoints to capture these opportunities, significantly delaying their ability to profit.
