There are several types of the nodes which support MEV and they are using different relays. For example, this is Flash-bots node https://etherscan.io/address/0xdafea492d9c6733ae3d56b7ed1adb60692c98bc5 and we can send tx to this node by using https://relay.flashbots.net relay.
What I would like to know is all of these relays. For example, I searched but I can not get the relay of this node. https://etherscan.io/address/0x8d5998a27b3cdf33479b65b18f075e20a7aa05b9 (MEV Builder: 0x8D...5b9)
Someone, please help me. Thanks
