How to Use Ignite to Create a Rollkit App

This guide will walk you through the process of using Ignite to create a Rollkit app.

Install Ignite

You can read more about Ignite here.

To install Ignite, you can run this command in your terminal:

curl https://get.ignite.com/cli@v28.5.3! | bash

Once Ignite is installed, scaffold a new blockchain with the following command:

ignite scaffold chain gm --address-prefix gm --minimal --skip-proto

This will create the gm blockchain. Navigate to the blockchain directory:

cd gm

Install Ignite App Rollkit

In a new terminal window, you'll now install and run the Ignite App Rollkit.

Run the following command to install the Rollkit App:

ignite app install github.com/ignite/apps/rollkit@rollkit/v0.2.1

This installs the Rollkit application, which will be integrated into your blockchain.

Add Rollkit Features

Enhance your blockchain by adding Rollkit features. Use the following command:

ignite rollkit add

Build your chain

Build your chain using the following command:

ignite chain build

Initialize Your Blockchain

Before starting your blockchain, you need to initialize it with Rollkit support. Initialize the blockchain with Local DA as follows:

ignite rollkit init

Initialize Rollkit CLI Configuration

To initialize the Rollkit CLI configuration, generate the rollkit.toml file by running the following command:

rollkit toml init

This will set up the Rollkit configuration file rollkit.toml, allowing you to use the Rollkit CLI for managing and running your blockchain.

Start your chain

Now you are ready to start your chain. We need to include 2 flags:

1. --rollkit.aggregator to signal that this node is the block producer
2. --rollkit.sequencer_rollup_id gm to share the chain ID with the sequencer.

Start your chain using the following command:

rollkit start --rollkit.aggregator --rollkit.sequencer_rollup_id gm

Your rollkit chain is now up and running.

Summary

By following these steps, you've successfully installed Ignite, integrated Rollkit features into your blockchain, and configured the Rollkit CLI to run your chain against a mock DA and mock sequencer.
