Welcome to Boba

This is the primary place where Boba works on the Boba L2, a compute-focused L2. Fundamentally, Ethereum is a distributed computer. We believe that L2s can play a unique role in augmenting the base compute capabilities of the Ethereum ecosystem. You can learn more about Turing hybrid compute here.

Boba is built on the Optimistic Rollup developed by Optimism. In addition to the native features of Optimism like bridging ETH and other tokens (including NFTs), Boba extends Optimism with compatible extensions including Hybrid Compute and Boba as a Fee Token. Boba is organized as a DAO.

User focused documentation is available here on the Boba docs website. If you have questions or feel like something is missing check out our Discord server where we are actively responding, or open an issue in the GitHub repo for this site.

The basic directory structure is laid out in the repository README.md.

Additionally, you will find specific Boba directories for:

  • boba-bindings: Go Bindings for the rollup smart contracts, including additional Boba contracts (like the DAO and the Boba Token).

  • boba-chain-ops: Tooling created to migrate the state of the original Boba network to Boba Anchorage.

  • boba-community: Easy to use docker-compose environments to execute a Boba replica.

Follow these instructions to set up your local development environment.

Dependencies

You'll need the following:

Note: this is only relevant to developers who wish to work on Boba core services. For most test uses, e.g. deploying your contracts, it's simpler to use the RPC provider at https://sepolia.boba.network.

Clone the repository, open it, and build with make:

$ git clone https://github.com/bobanetwork/boba.git
$ cd boba
$ make

Then, make sure you have Docker installed and make sure Docker is running. Finally, build and run the entire stack:

$ make devnet-up

Stack spinup can take 15 minutes or more. There are many interdependent services to bring up with multiple sets of contract deployment and initialization. More CPU cores and larger allocated RAM will help the process proceed more quickly.

Once the stack is up, you can verify its functionality with:

make devnet-test

  • Running out of space on your Docker, or having other having hard to debug issues? Try running docker system prune -a --volumes and then rebuild the images.

  • To (re)build services: make devnet-clean && make devnet-up

To run unit tests for a specific package:

cd packages/package-to-test
make test

Make sure you are in the op-e2e folder and then run

make

Even with parallelism enabled, these tests can take 10 or more minutes to execute, depending on the speed of your machine.

By default, the docker-compose up command will show logs from all services, and that can be hard to filter through. In order to view the logs from a specific service, you can run:

docker-compose logs --follow <service name>
