# nitro-bridge demo
## Setup
### L1 eth and L2 Optimism Stacks
- Clone the stack repo:
```bash
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:
```bash
# 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:
```bash
# 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):
```bash
docker image prune
```
- Create spec files for deployments, which will map the stack's ports and volumes to the host:
```bash
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`
```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`
```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:
```bash
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:
```bash
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:
```bash
laconic-so deployment --dir fixturenet-eth-deployment start
```
- Check status of L1
- Run status check:
```bash
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
```bash
laconic-so deployment --dir fixturenet-eth-deployment logs -f fixturenet-eth-geth-1
```
- Start `fixturenet-optimism-deployment` deployment:
```bash
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:
```bash
laconic-so deployment --dir fixturenet-optimism-deployment logs -f fixturenet-optimism-contracts
```
- Check L2 logs:
```bash
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
```bash
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:
```bash
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:
```bash
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:
```bash
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
```bash
laconic-so deployment --dir fixturenet-eth-deployment exec foundry "cast balance $ACCOUNT --rpc-url $L2_RPC"
# 100000000000000000
```
- Deploy L1 nitro contracts
- Create a deployment spec-file for L1 nitro contract:
```bash
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-contracts deploy init --output nitro-contracts-spec.yml --config "GETH_URL=http://host.docker.internal:8545,GETH_DEPLOYER_PK=888814df89c4358d7ddb3fa4b0213e7331239a80e1f013eaa7b2deca2a41a218,TOKEN_NAME=LaconicNetworkToken,TOKEN_SYMBOL=LNT,INITIAL_TOKEN_SUPPLY=129600"
```
- Create a deployment `nitro-contracts` from the spec file
```bash
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/nitro-contracts deploy create --spec-file nitro-contracts-spec.yml --deployment-dir nitro-contracts-deployment
```
- Start `nitro-contracts` deployment:
```bash
laconic-so deployment --dir nitro-contracts-deployment start
# Check the l1 nitro contract deployments
laconic-so deployment --dir nitro-contracts-deployment logs nitro-contracts -f
```
- Run the bridge:
- Get the deployed nitro contract addresses (run in the directory where the deployments were created):
```bash
# Nitro contract addresses
export NA_ADDRESS=$(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="$(laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.Token.address' /app/deployment/nitro-addresses.json")"
```
- Create a spec-file for the deployment, map container ports to host ports and set env variables:
```bash
laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/bridge deploy init --map-ports-to-host any-same --output bridge-nitro-spec.yml --config "NITRO_L1_CHAIN_URL=ws://host.docker.internal:8546,NITRO_L2_CHAIN_URL=ws://host.docker.internal:9546,NITRO_CHAIN_PK=888814df89c4358d7ddb3fa4b0213e7331239a80e1f013eaa7b2deca2a41a218,NITRO_SC_PK=0279651921cd800ac560c21ceea27aab0107b67daf436cdd25ce84cad30159b4,GETH_URL=http://host.docker.internal:8545,OPTIMISM_URL=http://host.docker.internal:9545,GETH_DEPLOYER_PK=$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"

laconic-so deployment --dir bridge-deployment start
# Check the l2 nitro contract deployments
laconic-so deployment --dir bridge-deployment logs l2-nitro-contracts -f
# Check the logs, ensure that the node is running
laconic-so deployment --dir bridge-deployment logs nitro-bridge -f
```
- Send custom tokens to Alice and Charlie on L1
- Export variables for L1 token address
```bash
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")"
export A_CHAIN_ADDRESS="0xe22AD83A0dE117bA0d03d5E94Eb4E0d80a69C62a"
export C_CHAIN_ADDRESS="0xf1ac8Dd1f6D6F5c0dA99097c57ebF50CD99Ce293"
```

### Payments Demo in L2
- Create virtual channel on L2 from A' to C' via Bridge' as intermediary
- Get Nitro (Ethereum) addresses for Alice and Charlie from the wallet:
```bash
export A_ADDRESS=0x4B64e26da8279AB12bcd4cA9974eC2b4741e175e
export C_ADDRESS=0x03Eb7a84E286c671836b9897AaE24b31D36f9cA8
# Bridge's Nitro address
export BRIDGE_NITRO_ADDRESS=0xBBB676f9cFF8D242e9eaC39D063848807d3D1D94
```
- Create a virtual channel:
```bash
# Starts virtual fund objective on L2 to create virtual channel from A' to C'
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-fund $C_ADDRESS $BRIDGE_NITRO_ADDRESS --amount 1000 -p 4005 -h nitro-node"
# Set the payment channel id in a variable
PAYMENT_CHANNEL_ID=<payment channel id>
```
- Check payment channel between A' and C'
```bash
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-payment-channel $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node"
# Expected output:
# {
# ID: '0xb29aeb32c9495a793ebf7bd116232075d1e7bfe89fc82281c7d498e3ffd3e3bf',
# Status: 'Open',
# Balance: {
# AssetAddress: '0x0000000000000000000000000000000000000000',
# Payee: '0xa8d2d06ace9c7ffc24ee785c2695678aecdfd7a0',
# Payer: '0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce',
# PaidSoFar: 0n,
# RemainingFunds: 1000n
# }
# }
```
- After virtual fund objective is complete, make payments
```bash
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client pay $PAYMENT_CHANNEL_ID 200 -p 4005 -h nitro-node"
# Expected output:
# {
# Amount: 200,
# Channel: '0xb29aeb32c9495a793ebf7bd116232075d1e7bfe89fc82281c7d498e3ffd3e3bf'
# }
```
- Check payment channel status again to view updated channel state
```bash
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-payment-channel $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node"
# Expected output:
# {
# ID: '0xb29aeb32c9495a793ebf7bd116232075d1e7bfe89fc82281c7d498e3ffd3e3bf',
# Status: 'Open',
# Balance: {
# AssetAddress: '0x0000000000000000000000000000000000000000',
# Payee: '0xa8d2d06ace9c7ffc24ee785c2695678aecdfd7a0',
# Payer: '0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce',
# PaidSoFar: 200n,
# RemainingFunds: 800n
# }
# }
```
- Close payment channel after payments
```bash
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-defund $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node"
```
- Check L2 mirrored channels status after virtual-defund is complete:
- Note balance change in A' node:
```bash
laconic-so deployment --dir l2alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
# Expected output:
# {"ID":"0x6a9f5ccf1fa802525d794f4a899897f947615f6acc7141e61e056a8bfca29179","Status":"Open","Balance":{"AssetAddress":"<Token_address_on_L2>","Me":"0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce","Them":"0xbbb676f9cff8d242e9eac39d063848807d3d1d94","MyBalance":999800,"TheirBalance":1000200},"ChannelMode":"Open"}
```
- Note balance change in C' node:
```bash
laconic-so deployment --dir l2charlie-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
# Expected output:
# {"ID":"0x15dbe6b996e4e46fdd6ea3e2074cbca58014dbb07368e3e7ba286df5c7b9da0d","Status":"Open","Balance":{"AssetAddress":"<Token_address_on_L2>","Me":"0xa8d2d06ace9c7ffc24ee785c2695678aecdfd7a0","Them":"0xbbb676f9cff8d242e9eac39d063848807d3d1d94","MyBalance":1000200,"TheirBalance":999800},"ChannelMode":"Open"}
```
## Demo cleanup
- Reset nitro-node deployments:
- Stop nitro-node deployments and remove volumes:
```bash
# Run where deployments are created
laconic-so deployment --dir l1alice-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l1charlie-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l2alice-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l2charlie-nitro-deployment stop --delete-volumes
laconic-so deployment --dir bridge-deployment stop --delete-volumes
```
- Clear nitro-nodes durable store:
```bash
# Run where deployments are created
sudo rm -rf l1alice-nitro-deployment/data/nitro_node_data/nitro-store
sudo rm -rf l1charlie-nitro-deployment/data/nitro_node_data/nitro-store
sudo rm -rf l2alice-nitro-deployment/data/nitro_node_data/nitro-store
sudo rm -rf l2charlie-nitro-deployment/data/nitro_node_data/nitro-store
sudo rm -rf bridge-deployment/data/nitro_bridge_data/bridge-store
```
## Re-run
- After running demo cleanup, start the deployments
```bash
laconic-so deployment --dir l1alice-nitro-deployment start
laconic-so deployment --dir l1charlie-nitro-deployment start
laconic-so deployment --dir l2alice-nitro-deployment start
laconic-so deployment --dir l2charlie-nitro-deployment start
laconic-so deployment --dir bridge-deployment start
```
- Follow the steps from [Demo](#demo) to re-run the demo
## Cleanup
- Reset nitro-node deployments:
- Stop nitro-node, bridge, nitro-contracts deployments and remove volumes:
```bash
# Run where deployments are created
laconic-so deployment --dir l1alice-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l1charlie-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l2alice-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l2charlie-nitro-deployment stop --delete-volumes
laconic-so deployment --dir bridge-deployment stop --delete-volumes
laconic-so deployment --dir nitro-contracts-deployment stop --delete-volumes
```
- Clear nitro-node, nitro-contracts and bridge deployments:
```bash
# Run where deployments are created
sudo rm -rf l1alice-nitro-deployment
sudo rm -rf l1charlie-nitro-deployment
sudo rm -rf l2alice-nitro-deployment
sudo rm -rf l2charlie-nitro-deployment
sudo rm -rf bridge-deployment
sudo rm -rf nitro-contracts-deployment
```
- Clean up L1 and L2 deployments:
- Stop deployment and remove volumes:
```bash
# 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:
```bash
# 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` is `unhealthy`.
```bash
docker ps
```
- If the chain is not producing new blocks, restart the chain.
```bash
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
```bash
laconic-so deployment --dir l1charlie-nitro-deployment stop
```
- Remove the node's durable store and create it again
```bash
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
```bash
laconic-so deployment --dir l1charlie-nitro-deployment start
```
- Retry the ledger channel creation command
