Running Rollup Boost Locally

To run a local development network, you can use either Kurtosis or builder-playground to spin up the op-stack with rollup-boost.

Builder Playground

Builder playground is a tool to deploy an end-to-end block builder environment locally. It can be used to test both L1 and OP Stack block builders.

This will include deploying an OP Stack chain with:

• A complete L1 setup (CL/EL)
• A complete L2 sequencer (op-geth/op-node/op-batcher)
• Op-rbuilder as the external block builder with Flashblocks support

builder-playground cook opstack --external-builder op-rbuilder

Flags:

--enable-latest-fork (int): Enables the latest fork (isthmus) at startup (0) or n blocks after genesis. --flashblocks: Enables rollup-boost with Flashblocks enabled for pre-confirmations

In this setup, there is a prefunded test account to send test transactions to:

• address: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266
• private key: ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Kurtosis

Kurtosis is a tool to manage containerized services. To run rollup-boost in an op-stack devnet, first make sure you have just and kurtosis-cli installed.

This would include spinning up:

• sequencer op-node and op-geth
• builder op-node and op-rbuilder
• rollup boost rollup-boost
• ethereum l1 devnet with l2 contracts deployed
• op-proposer and op-batcher

Then run the following command to start the devnet:

just devnet-up

To stop the devnet run:

just devnet-down

To run a stress test against the devnet with contender, first make sure you have Docker installed.

Then run the following command:

just stress-test

See the optimism package for additional configuration options.
