# Overview

**BackRunMe** is bloXroute’s backrun arbitrage system that enables MEV searchers to extract value from private transactions submitted through bloXroute’s RPC services. These transactions remain hidden from the public mempool. If a transaction creates an arbitrage opportunity, the sender may receive a rebate from the resulting profit.

The program is available on the following chains: ETH, BSC, Base, X Layer, Hyperliquid, and Monad.

### **How It Works**

* A private transaction is submitted through bloXroute — either via our RPC service or by using the private transaction or bundle submission endpoints.
* If the transaction creates an arbitrage opportunity, it is forwarded (anonymized) to MEV searchers via the `arbOnlyMEV` stream.
* Searchers submit backrun-only bundles that reference the private transaction.
* If successful, profits are distributed among the transaction sender, the searcher, block proposer, and bloXroute.

### **How to Participate**

BackRunMe supports two user types:

#### **Private Transaction Senders**

Participation is seamless when using bloXroute’s RPC services. Transactions are automatically protected and eligible for rebates when they create MEV opportunities.\
If submitting via bundle or private transaction, include:

* `enable_backrunme = true`
* `backrunme_reward_address = <your address>`

#### **MEV Searchers**
