Welcome to Optimism Package

The default package for Optimism

optimism_package:
  chains:
    - participants:
        - el_type: op-geth
          cl_type: op-node
        - el_type: op-reth
        - el_type: op-erigon
        - el_type: op-nethermind
ethereum_package:
  network_params:
    preset: minimal

Please note, by default your network will be running a minimal preset Ethereum network. Click here to learn more about minimal preset. You can customize the L1 Ethereum network by modifying the ethereum_package configuration.

You can also completely remove ethereum_package from your configuration in which case it will default to a minimal preset Ethereum network.

Quickstart

Run with your own configuration

Kurtosis packages are parameterizable, meaning you can customize your network and its behavior to suit your needs by storing parameters in a file that you can pass in at runtime like so:

kurtosis run github.com/ethpandaops/optimism-package --args-file https://raw.githubusercontent.com/ethpandaops/optimism-package/main/network_params.yaml

For --args-file you can pass a local file path or a URL to a file.

To clean up running enclaves and data, you can run:

kurtosis clean -a

This will stop and remove all running enclaves and delete all data.

L2 Contract deployer

The enclave will automatically deploy an optimism L2 contract on the L1 network. The contract address will be printed in the logs. You can use this contract address to interact with the L2 network.

Please refer to this Dockerfile if you want to see how the contract deployer image is built: Dockerfile

Configuration

To configure the package behaviour, you can modify your network_params.yaml file. The full YAML schema that can be passed in is as follows with the defaults provided:

Additional configuration recommendations

It is required you to launch an L1 Ethereum node to interact with the L2 network. You can use the ethereum_package to launch an Ethereum node. The ethereum_package configuration is as follows:

optimism_package:
  chains:
    - participants:
        - el_type: op-geth
          cl_type: op-node
      additional_services:
        - blockscout
ethereum_package:
  participants:
    - el_type: geth
    - el_type: reth
  network_params:
    preset: minimal
  additional_services:
    - dora
    - blockscout

Additionally, you can spin up multiple L2 networks by providing a list of L2 configuration parameters like so:

optimism_package:
  chains:
    - participants:
        - el_type: op-geth
      network_params:
        name: op-rollup-one
        network_id: "3151909"
      additional_services:
        - blockscout
    - participants:
        - el_type: op-geth
      network_params:
        name: op-rollup-two
        network_id: "3151910"
      additional_services:
        - blockscout
ethereum_package:
  participants:
    - el_type: geth
    - el_type: reth
  network_params:
    preset: minimal
  additional_services:
    - dora
    - blockscout

Note: if configuring multiple L2s, make sure that the network_id and name are set to differentiate networks.
