Run a Local Rollup and Sequencer ​

This guide will walk you through running a local Geth rollup against the Astria sequencer, using the astria-go cli to run the required components of the Astria stack locally on your machine.

Setup a Geth Rollup ​

Requires Go, just, and Foundry:

Open a new terminal window and clone and build Geth:

Create a new genesis account for your Geth rollup:

bash
cast w new

Open the geth-genesis-local.json file in your Geth repo and update the "alloc" account with the new address you just created, as well as updating the "chainId" and "astriaRollupName" to something of your choosing:

json
{
    "config": {
        ...
        "chainId": <6 digit number>,
        "astriaRollupName": "<your rollup name>",
        ...
        "alloc": {
            "<your new address>": { "balance": "300000000000000000000" }
        }
    }
}

You will use the private key for your new account to send test transactions later on.

Start Geth ​

In your Geth terminal window, run the following to initialize and run the Geth rollup:

bash
# in astria-geth dir
just init
just run

If you need to restart the rollup, you can stop the program with Ctrl+C and restart with:

bash
just run

If you need to restart the rollup and want to also clear the state data, you can use:

bash
just clean-restart

Configure and Start the Local Astria Sequencer ​

Open a new terminal window and initialize the cli:

bash
astria-go dev init

Navigate to the ~/.astria directory. If you have run the commands shown above, you should find a default directory.

Open the ~/.astria/default/networks-config.toml file and update the rollup_name variable in the [local] sections using the same "astriaRollupName" you used when setting up your Geth rollup.

toml
[networks.local]
sequencer_chain_id = 'sequencer-test-chain-0'
sequencer_grpc = 'http://127.0.0.1:8080'
sequencer_rpc = 'http://127.0.0.1:26657'
rollup_name = '<your rollup name>' # update this value
default_denom = 'ntia'

Use the cli to run a local Astria Sequencer.

bash
astria-go dev run --network local

TIP

When running an Astria sequencer using the cli, the --network local setting is the default. astria-go dev run is effectively an alias for astria-go dev run --network local.

When running the Astria stack locally, you will see a TUI that displays the logs of the Astria Sequencer, the underlying Cometbft node, the Astria Conductor, and Astria Composer: Running a local sequencer in the Astria cli

Test your Rollup ​

To test that your rollup and the sequencer are configured and running correctly, you can follow the Test Transactions instructions here.
