How to connect a rollup to a local DA network

This guide provides a quick and straightforward method to start a local Data Availability (DA) network and configure your rollup to post data to it.

Setting Up a Local DA Network

To set up a local DA network node on your machine, run the following script to install and start the local DA node:

curl -sSL https://rollkit.dev/install-local-da.sh | bash -s v0.3.1

This script will build and run the node, which will then listen on port 7980.

Configuring your rollup to connect to the local DA network

To connect your rollup to the local DA network, you need to pass the --rollkit.da_address flag with the local DA node address.

Run your rollup

Start your rollup node with the following command, ensuring to include the DA address flag:

rollkit start \
    --rollkit.da_address http://localhost:7980 \
    <other-flags>

Summary

By following these steps, you will set up a local DA network node and configure your rollup to post data to it. This setup is useful for testing and development in a controlled environment.
