Instructions to setup and deploy L2 fixturenet using Optimism

Setup

Prerequisite: An L1 Ethereum RPC endpoint

Clone required repositories:

laconic-so --stack fixturenet-optimism setup-repositories --exclude cerc-io/go-ethereum

# If this throws an error as a result of being already checked out to a branch/tag in a repo, remove the repositories mentioned below and re-run the command

Checkout to the required versions and branches in repos:

# Optimism
cd ~/cerc/optimism
git checkout v1.0.4

Build the container images:

laconic-so --stack fixturenet-optimism build-containers --include cerc/foundry,cerc/optimism-contracts,cerc/optimism-op-node,cerc/optimism-l2geth,cerc/optimism-op-batcher,cerc/optimism-op-proposer

This should create the required docker images in the local image registry:

• cerc/foundry
• cerc/optimism-contracts
• cerc/optimism-l2geth
• cerc/optimism-op-node
• cerc/optimism-op-batcher
• cerc/optimism-op-proposer

Deploy

Create and update an env file to be used in the next step (defaults):

# External L1 endpoint
CERC_L1_CHAIN_ID=
CERC_L1_RPC=
CERC_L1_HOST=
CERC_L1_PORT=

# URL to get CSV with credentials for accounts on L1
# that are used to send balance to Optimism Proxy contract
# (enables them to do transactions on L2)
CERC_L1_ACCOUNTS_CSV_URL=

# OR
# Specify the required account credentials
CERC_L1_ADDRESS=
CERC_L1_PRIV_KEY=
CERC_L1_ADDRESS_2=
CERC_L1_PRIV_KEY_2=

• NOTE: If L1 is running on the host machine, use host.docker.internal as the hostname to access the host port

Deploy the stack:

laconic-so --stack fixturenet-optimism deploy --include fixturenet-optimism --env-file <PATH_TO_ENV_FILE> up

The fixturenet-optimism-contracts service may take a while (~15 mins) to complete running as it:

1. waits for the 'Merge' to happen on L1
2. waits for a finalized block to exist on L1 (so that it can be taken as a starting block for roll ups)
3. deploys the L1 contracts

To list down and monitor the running containers:

laconic-so --stack fixturenet-optimism deploy --include fixturenet-optimism ps

# With status
docker ps

# Check logs for a container
docker logs -f <CONTAINER_ID>

Clean up

Stop all services running in the background:

laconic-so --stack fixturenet-optimism deploy --include fixturenet-optimism down 30

Clear volumes created by this stack:

# List all relevant volumes
docker volume ls -q --filter "name=.*l1_deployment|.*l2_accounts|.*l2_config|.*l2_geth_data"

# Remove all the listed volumes
docker volume rm $(docker volume ls -q --filter "name=.*l1_deployment|.*l2_accounts|.*l2_config|.*l2_geth_data")
