Request the example for deploying OP rollup to public testnet

[lesterli]

Hello, we’re working on deploying an OP rollup on Sepolia. The Kurtosis package is quite easy to use, and one command sets everything up. However, I haven’t found an example for deploying an OP rollup on a public testnet, like Sepolia.

Could you confirm if the following configuration is suitable for spinning up an OP L2 chain on Sepolia?

optimism_package:
  chains:
    - participants:
        - el_type: op-geth
          cl_type: op-node
ethereum_package:
  network_params:
    network: sepolia

Additionally, our team is a start-up, we’ve made minimal modifications to the OP node codebase, would it be possible to modify the Kurtosis package to support spinning up a customized op-node?

OP sepolia is currently not supported out of the box.

customizing the op_node can be done with cl_image: <your-local-image>. Take a look at the readme.

thanks for the quick reply! if we want to contribute to add the support, could you provide some high-level guidance which code we need to modify?

we studied the codebase and came up with a plan to support external L1.

right now we want to figure out how to support two modes:

• with proposer (fault proof disabled)
• with challenger (fault proof enabled)
