Sending your first bundle

The quickest way to start sending bundles is to try out the CLI client in our searcher-examples repo.

Prerequisites: make sure you have set up your environment, as described in Getting Started

  1. Set up the searcher-examples repo

There are two ways of using the grpc endpoint.

  1. Without any authentication. Follow the example code without the auth key to access block engine

  2. With authentication. The block engine uses a challenge-response authentication mechanism with messages signed by a local Solana keypair. This local keypair shouldn't contain funds and doesn't need to be related to the keypair you sign transactions or submit bundles for.

For default rate limits, there is no difference between using the authentication vs not using authentication.

Note: A sample ts client can be found at https://github.com/jito-labs/jito-ts
