Setup

Make sure to first install the prerequisites from the quickstart section before proceeding.

Installation

Before you can start migrating your rollup, you'll need to build and install Kailua's binaries by calling the following commands from the root project directory:

Tip

If you have modified the FPVM binary, you will need to build/install using -F rebuild-fpvm.

Info

At the cost of longer compilation time, you can embed the RISC Zero zkvm prover logic into kailua-cli instead of having it utilize your locally installed RISC Zero r0vm for proving. To do this, add -F prove to the install command below.

Tip

For GPU-accelerated local proving, use one of the following feature flags:

  • Apple: -F metal
  • Nvidia: -F cuda

CLI Binary

cargo install kailua-cli --path bin/cli --locked

Configuration

Once your installation is successful, you should be able to run the following command to fetch the Kailua configuration parameters for your rollup instance:

kailua-cli config --op-node-url [YOUR_OP_NODE_URL] --op-geth-url [YOUR_OP_GETH_URL] --eth-rpc-url [YOUR_ETH_RPC_URL]

Running the above command against the respective Base mainnet endpoints should produce the following output:

RISC0_VERSION: 2.1.0

Warning

Make sure that your FPVM_IMAGE_ID matches the value above. This value determines the exact program used to prove faults.

Note

If your RISC_ZERO_VERIFIER value is blank, this means that your rollup might be deployed on a base layer that does not have a deployed RISC Zero zkVM verifier contract. This means you might have to deploy your own verifier. Always revise the RISC Zero documentation to double-check verifier availability.

Once you have these values you'll need to save them for later use during migration.

Telemetry

All Kailua binaries and commands support exporting telemetry data to an OTLP Collector. The collector endpoint can be specified using the --otlp-collector parameter, or through specifying the OTLP_COLLECTOR environment variable.
