# MEV Protection

For instances of Skandha that you run yourself, Etherspot have
added options to protect your UserOps against frontrunners and
many other types of MEV.

We've done this by integrating the [Flashbots Auction API](https://docs.flashbots.net/flashbots-auction/overview)
which is a permissionless, transparent, and fair ecosystem
for efficient MEV extraction and frontrunning protection which
preserves the ideals of Ethereum. Flashbots Auction provides
a private communication channel between Ethereum users and
validators for efficiently communicating preferred transaction
order within a block.

This can be enabled by following [the Skandha installation](/skandha/installation)
page and changing **rpcEndpointSubmit** and **relayingMode** in config.json like so:

```json theme={null}
{
  "networks": {
    "sepolia": {
      "entryPoints": [
        "0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789"
      ],
      "relayer": "0x{PRIVATE-KEY}",
      "beneficiary": "0x{BENEFICIARY-ADDRESS}",
      "rpcEndpoint": "wss://ethereum-sepolia-rpc.publicnode.com	",
      "rpcEndpointSubmit": "https://relay-sepolia.flashbots.net",
      "relayingMode": "flashbots"
    }
  }
}
```

Relayer URLs:

| Network | URL                                                                          |
