Introduction

The Ethereum Private Mempool delivers private transaction stream data, which is pushed based on the SSE protocol. Transactions within the data stream are uniformly desensitized, disclosing only transaction fields authorized for release.

Private Mempool can be applied to a variety of scenarios, including backrunning, copy trading, and sniping.

To avoid data interruption due to network fluctuations, it is recommended to establish a reconnection mechanism.

Endpoint

Please keep the domain for subscribing to bundles consistent with the domain for sending bundles. For example, if you subscribe to https://jp-ethscutum.blockrazor.xyz/stream, send bundles to https://jp-ethscutum.blockrazor.xyz.

Private data streams vary across regions. It is recommended to subscribe to both endpoints simultaneously.
