Setup
L1 eth and L2 Optimism Stacks
-
Clone the stack repo:
laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-eth-stacks --pull laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-optimism-stack --pull
-
Clone required repositories:
# L1 (fixturenet-eth) laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth setup-repositories --pull # L2 (optimism) laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism setup-repositories --pull # If this throws an error as a result of being already checked out to a branch/tag in a repo, remove all repositories from that stack and re-run the command # The repositories are located in $HOME/cerc by default
-
Build the container images:
# Remove any older foundry image with `latest` tag docker rmi ghcr.io/foundry-rs/foundry:latest # L1 (fixturenet-eth) laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth build-containers --force-rebuild # L2 (optimism) laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism build-containers --force-rebuild # If errors are thrown during build, old images used by this stack would have to be deleted
-
NOTE: this will take >10 mins depending on the specs of your machine, and requires 16GB of memory or greater.
-
Remove any dangling Docker images (to clear up space):
docker image prune
-
-
Create spec files for deployments, which will map the stack's ports and volumes to the host:
laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy init --output fixturenet-eth-spec.yml laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism deploy init --output fixturenet-optimism-spec.yml
-
Configure ports:
-
fixturenet-eth-spec.yml
... network: ports: fixturenet-eth-bootnode-geth: - '9898:9898' - '30303' fixturenet-eth-geth-1: - '8545:8545' - '8546:8546' - '40000' - '6060' fixturenet-eth-lighthouse-1: - '8001' ...
-
fixturenet-optimism-spec.yml
... network: ports: op-geth: - '9545:8545' - '9546:8546' ...
-
-
Create deployments: Once you've made any needed changes to the spec files, create deployments from them:
laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy create --spec-file fixturenet-eth-spec.yml --deployment-dir fixturenet-eth-deployment laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism deploy create --spec-file fixturenet-optimism-spec.yml --deployment-dir fixturenet-optimism-deployment # Place them both in the same namespace (cluster) cp fixturenet-eth-deployment/deployment.yml fixturenet-optimism-deployment/deployment.yml
-
Env configuration:
cat <<EOF > fixturenet-eth-deployment/config.env CERC_ALLOW_UNPROTECTED_TXS=true EOF

Run
-
Start L1, L2 stacks: (run steps in directory where the stack deployments had been created)
-
Start
fixturenet-eth-deployment
deployment:laconic-so deployment --dir fixturenet-eth-deployment start
-
Check status of L1
-
Run status check:
laconic-so deployment --dir fixturenet-eth-deployment exec fixturenet-eth-bootnode-lighthouse "/scripts/status-internal.sh"
-
Check geth logs to ensure that new blocks are getting created
laconic-so deployment --dir fixturenet-eth-deployment logs -f fixturenet-eth-geth-1
-
-
-
Start
fixturenet-optimism-deployment
deployment:laconic-so deployment --dir fixturenet-optimism-deployment start
NOTE: The
fixturenet-optimism-contracts
service will configure and deploy the Optimism contracts to L1, exiting when complete. This may take several minutes; you can follow the progress by following the container's logs-
Follow optimism contracts deployment logs:
laconic-so deployment --dir fixturenet-optimism-deployment logs -f fixturenet-optimism-contracts
-
Check L2 logs:
laconic-so deployment --dir fixturenet-optimism-deployment logs -f op-geth # Ensure new blocks are getting created
-
-
-
Send ETH from L1 to L2 (run steps in directory where the stack deployments had been created)
-
Get information about funded accounts on L1
curl 127.0.0.1:9898/accounts.csv
-
Send some ETH from the desired account to the
L1StandardBridgeProxy
contract on L1 to bridge it to L2:-
Set the following variables:
L1_RPC=http://fixturenet-eth-geth-1:8545 L2_RPC=http://op-geth:8545 DEPLOYMENT_CONTEXT=1212 ACCOUNT=0xe6CE22afe802CAf5fF7d3845cec8c736ecc8d61F
-
Read the bridge contract address from the L1 deployment records in the
op-node
container:BRIDGE=$(laconic-so deployment --dir fixturenet-optimism-deployment exec op-node "cat /l1-deployment/$DEPLOYMENT_CONTEXT-deploy.json" | jq -r .L1StandardBridgeProxy) # Get the funded account's pk ACCOUNT_PK=$(laconic-so deployment --dir fixturenet-optimism-deployment exec op-node "jq -r '.AdminKey' /l2-accounts/accounts.json")
-
Use cast to send ETH to the bridge contract:
laconic-so deployment --dir fixturenet-eth-deployment exec foundry "cast send --from $ACCOUNT --value 1ether $BRIDGE --rpc-url $L1_RPC --private-key $ACCOUNT_PK"
NOTE: This is for sending funds to the contracts deployer account which is also the Bridge node account
-
Allow a couple minutes for the bridge to complete
-
-
Check balance on L2
laconic-so deployment --dir fixturenet-eth-deployment exec foundry "cast balance $ACCOUNT --rpc-url $L2_RPC" # 100000000000000000
-
-
Deploy L1 nitro contracts
-
Create a deployment spec-file for L1 nitro contract:
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-contracts deploy init --output nitro-contracts-spec.yml --config "GETH_URL=http://host.docker.internal:8545,GETH_DEPLOYER_PK=888814df89c4358d7ddb3fa4b0213e7331239a80e1f013eaa7b2deca2a41a218,TOKEN_NAME=LaconicNetworkToken,TOKEN_SYMBOL=LNT,INITIAL_TOKEN_SUPPLY=129600"
-
Create a deployment
nitro-contracts
from the spec filelaconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-contracts deploy create --spec-file nitro-contracts-spec.yml --deployment-dir nitro-contracts-deployment
-
Start
nitro-contracts
deployment:laconic-so deployment --dir nitro-contracts-deployment start # Check the l1 nitro contract deployments laconic-so deployment --dir nitro-contracts-deployment logs nitro-contracts -f
-
-
Run the bridge:
-
Get the deployed nitro contract addresses (run in the directory where the deployments were created):
# Nitro contract addresses export NA_ADDRESS=$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.NitroAdjudicator.address' /app/deployment/nitro-addresses.json") export CA_ADDRESS=$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.ConsensusApp.address' /app/deployment/nitro-addresses.json") export VPA_ADDRESS=$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.VirtualPaymentApp.address' /app/deployment/nitro-addresses.json") export L1_ASSET_ADDRESS="$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.Token.address' /app/deployment/nitro-addresses.json")"
-
Create a spec-file for the deployment, map container ports to host ports and set env variables:
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/bridge deploy init --map-ports-to-host any-same --output bridge-nitro-spec.yml --config "NITRO_L1_CHAIN_URL=ws://host.docker.internal:8546,NITRO_L2_CHAIN_URL=ws://host.docker.internal:9546,NITRO_CHAIN_PK=888814df89c4358d7ddb3fa4b0213e7331239a80e1f013eaa7b2deca2a41a218,NITRO_SC_PK=0279651921cd800ac560c21ceea27aab0107b67daf436cdd25ce84cad30159b4,GETH_URL=http://host.docker.internal:8545,OPTIMISM_URL=http://host.docker.internal:9545,GETH_DEPLOYER_PK=$ACCOUNT_PK,OPTIMISM_DEPLOYER_PK=$ACCOUNT_PK,TOKEN_NAME=LaconicNetworkToken,TOKEN_SYMBOL=LNT,INITIAL_TOKEN_SUPPLY=129600,NA_ADDRESS=$NA_ADDRESS,VPA_ADDRESS=$VPA_ADDRESS,CA_ADDRESS=$CA_ADDRESS,L1_ASSET_ADDRESS=$L1_ASSET_ADDRESS"

-
-
Clean up L1 and L2 deployments:
-
Stop deployment and remove volumes:
# Run where deployments are created laconic-so deployment --dir fixturenet-optimism-deployment stop --delete-volumes laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes
-
Clear deployments:
# Run where deployments are created sudo rm -rf fixturenet-optimism-deployment sudo rm -rf fixturenet-eth-deployment
-
Troubleshooting
-
If the ledger channel creation fails, follow these steps:
-
Check whether the status of
cerc/fixturenet-eth-geth
isunhealthy
.docker ps
-
If the chain is not producing new blocks, restart the chain.
laconic-so deployment --dir fixturenet-eth-deployment stop laconic-so deployment --dir fixturenet-eth-deployment start
-
-
Stop the nitro-rpc-client direct-fund command if it is stuck
-
Restart the failed node (for example: to restart Charlie's node)
-
Stop the failed nitro node
laconic-so deployment --dir l1charlie-nitro-deployment stop
-
Remove the node's durable store and create it again
sudo rm -rf l1charlie-nitro-deployment/data/nitro_node_data mkdir l1charlie-nitro-deployment/data/nitro_node_data
-
Restart the node and create ledger channel again
laconic-so deployment --dir l1charlie-nitro-deployment start
-
-
Retry the ledger channel creation command
