Flashblocks Websocket Proxy

Overview

The Flashblocks Websocket Proxy is a service that subscribes to new Flashblocks from rollup-boost on the sequencer. Then broadcasts them out to any downstream RPC nodes. Minimizing the number of connections to the sequencer and restricting access.

⚠️ Warning

This is currently alpha software -- deploy at your own risk!

Currently, this project is a one-directional generic websocket proxy. It doesn't inspect any data or validate clients. This may not always be the case.
