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.
