## Prerequisites
* Local:
* Clone the `cerc-io/testnet-ops` repository:
```bash
git clone git@git.vdb.to:cerc-io/testnet-ops.git
```
* Ansible: see [installation](https://git.vdb.to/cerc-io/testnet-ops#installation)

<summary>L2 Optimism</summary>
## L2 Optimism
* Stack: <https://git.vdb.to/cerc-io/fixturenet-optimism-stack>
* Source repos:
* <github.com/ethereum-optimism/optimism@v1.7.7>
* <github.com/ethereum-optimism/op-geth@v1.101315.2>
* Target dir: `/srv/op-sepolia/optimism-deployment`
* Cleanup an existing deployment on VM if required:
```bash
cd /srv/op-sepolia
# Stop the deployment
laconic-so deployment --dir optimism-deployment stop --delete-volumes
# Remove the deployment dir
sudo rm -rf optimism-deployment
```
### Setup
* Switch to `testnet-ops/l2-setup` directory on your local machine:
```bash
cd testnet-ops/l2-setup
```
* Copy the `l2-vars-example.yml` vars file:
```bash
cp l2-vars-example.yml l2-vars.yml
```
* Edit `l2-vars.yml` with required values:
```bash
# L1 chain ID (Sepolia: 11155111)
l1_chain_id: "11155111"
# L1 RPC endpoint
l1_rpc: "http://host.docker.internal:8545"
# L1 RPC endpoint host or IP address
l1_host: "host.docker.internal"
# L1 RPC endpoint port number
l1_port: "8545"
# L1 Beacon endpoint
l1_beacon: "http://host.docker.internal:8001"
# Account credentials for the Admin account
# Used for Optimism contracts deployment and funding other generated accounts
l1_address: ""
l1_priv_key: ""
```
* Update the target dir in `setup-vars.yml`:
```bash
sed -i 's|^l2_directory:.*|l2_directory: /srv/op-sepolia|' setup-vars.yml
# Will create deployment at /srv/op-sepolia/optimism-deployment
```
### Run
* Set up and run L2 on remote host by executing `run-optimism.yml` Ansible playbook on your local machine:
* Create a new `hosts.ini` file:
```bash
cp ../hosts.example.ini hosts.ini
```
* Edit the [`hosts.ini`](./hosts.ini) file to run the playbook on a remote machine:
```ini
[l2_host]
<host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
```
- Replace `<host_name>` with the alias of your choice
- Replace `<target_ip>` with the IP address or hostname of the target machine
- Replace `<ssh_user>` with the SSH username (e.g., dev, ubuntu)
* Verify that you are able to connect to the host using the following command:
```bash
ansible all -m ping -i hosts.ini -k
# Expected output:
# <host_name> | SUCCESS => {
# "ansible_facts": {
# "discovered_interpreter_python": "/usr/bin/python3.10"
# },
# "changed": false,
# "ping": "pong"
# }
```
* Execute the `run-optimism.yml` Ansible playbook for remote deployment:
```bash
LANG=en_US.utf8 ansible-playbook -i hosts.ini run-optimism.yml --extra-vars='{ "target_host": "l2_host"}' --user $USER -kK
```
* Bridge funds on L2:
* On the deployment VM, set the following variables:
```bash
cd /srv/op-sepolia
L1_RPC=http://host.docker.internal:8545
L2_RPC=http://host.docker.internal:9545
NETWORK=$(grep 'cluster-id' optimism-deployment/deployment.yml | sed 's/cluster-id: //')_default
DEPLOYMENT_CONTEXT=11155111
ACCOUNT=<admin-account-address>
```
* Read the bridge contract address from the L1 deployment records in the `op-node` container:
```bash
BRIDGE=$(laconic-so deployment --dir optimism-deployment exec op-node "cat /l1-deployment/$DEPLOYMENT_CONTEXT-deploy.json" | jq -r .L1StandardBridgeProxy)
# Get the funded account's pk
ACCOUNT_PK=$(laconic-so deployment --dir optimism-deployment exec op-node "jq -r '.AdminKey' /l2-accounts/accounts.json")
```
* Check that the starting balance for account on L2 is 0:
```bash
docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast balance $ACCOUNT --rpc-url $L2_RPC"
# 0
```
* Use cast to send ETH to the bridge contract:
```bash
docker run --rm cerc/optimism-contracts:local "cast send --from $ACCOUNT --value 1ether $BRIDGE --rpc-url $L1_RPC --private-key $ACCOUNT_PK"
```
* Allow a couple minutes for the bridge to complete
* Check balance on L2:
```bash
docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast balance $ACCOUNT --rpc-url $L2_RPC"
# 100000000000000000
```

# testnet-nitro-node
## Prerequisites
* Ansible: see [installation](https://git.vdb.to/cerc-io/testnet-ops#installation)
* yq: see [installation](https://github.com/mikefarah/yq#install)
* laconic-so: see [installation](https://git.vdb.to/cerc-io/testnet-ops/src/branch/main/stack-orchestrator-setup/README.md)
* Check versions to verify installation:
```bash
laconic-so version
ansible --version
yq --version
```
## Setup
* Clone the `cerc-io/testnet-ops` repository:
```bash
git clone git@git.vdb.to:cerc-io/testnet-ops.git
cd testnet-ops/nitro-node-setup
```
* Fetch the required Nitro node config:
```bash
wget -O nitro-vars.yml https://git.vdb.to/cerc-io/testnet-laconicd-stack/raw/branch/main/ops/stage2/nitro-node-config.yml
# Expected variables in the fetched config file:
# nitro_l1_chain_url: ""
# nitro_l2_chain_url: ""
# na_address: ""
# ca_address: ""
# vpa_address: ""
# l1_asset_address: ""
# bridge_contract_address: ""
# bridge_nitro_address: ""
# nitro_l1_bridge_multiaddr: ""
# nitro_l2_bridge_multiaddr: ""
```
* TODO: Get L1 tokens on your address
* Edit `nitro-vars.yml` and add the following variables:
```bash
# Private key for your Nitro account (same as the one used in stage0 onboarding)
# Export the key from Laconic wallet (https://wallet.laconic.com)
nitro_sc_pk: ""
# Private key for a funded account on L1
# This account should have L1 tokens for funding your Nitro channels
nitro_chain_pk: ""
# Multiaddr with publically accessible IP address / DNS for your L1 nitro node
# Use port 3007
# Example: "/ip4/192.168.x.y/tcp/3007"
# Example: "/dns4/example.com/tcp/3007"
nitro_l1_ext_multiaddr: ""
# Multiaddr with publically accessible IP address / DNS for your L2 nitro node
# Use port 3009
# Example: "/ip4/192.168.x.y/tcp/3009"
# Example: "/dns4/example.com/tcp/3009"
nitro_l2_ext_multiaddr: ""
```
* Update the target dir in `setup-vars.yml`:
```bash
# Set path to desired deployments dir
DEPLOYMENTS_DIR=<path-to-deployments-dir>
sed -i "s|^nitro_directory:.*|nitro_directory: $DEPLOYMENTS_DIR/nitro-node|" setup-vars.yml
# Will create deployments at $DEPLOYMENTS_DIR/nitro-node/l1-nitro-deployment and $DEPLOYMENTS_DIR/nitro-node/l2-nitro-deployment
```
## Run Nitro Nodes
### On Local Host
* Setup and run a Nitro node (L1+L2) by executing the `run-nitro-nodes.yml` Ansible playbook:
```bash
LANG=en_US.utf8 ansible-playbook -i localhost, --connection=local run-nitro-nodes.yml --extra-vars='{ "target_host": "localhost"}' --user $USER
```
### On Remote Host (optional)
* Create a new `hosts.ini` file:
```bash
cp ../hosts.example.ini hosts.ini
```
* Edit the [`hosts.ini`](./hosts.ini) file to run the playbook on a remote machine:
```ini
[nitro_host]
<host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
```
- Replace `<host_name>` with the alias of your choice
- Replace `<target_ip>` with the IP address or hostname of the target machine
- Replace `<ssh_user>` with the SSH username (e.g., dev, ubuntu)
* Verify that you are able to connect to the host using the following command
```bash
ansible all -m ping -i hosts.ini -k
# Expected output:
# <host_name> | SUCCESS => {
# "ansible_facts": {
# "discovered_interpreter_python": "/usr/bin/python3.10"
# },
# "changed": false,
# "ping": "pong"
# }
```
* Execute the `run-nitro-nodes.yml` Ansible playbook for remote deployment:
```bash
LANG=en_US.utf8 ansible-playbook -i hosts.ini run-nitro-nodes.yml --extra-vars='{ "target_host": "nitro_host"}' --user $USER -kK
```
### Check Deployment Status
* Run the following command in the directory where the deployments are created:
```bash
cd $DEPLOYMENTS_DIR/nitro-node
# Check the logs, ensure that the nodes are running
laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f
laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f
```
## Create Channels
Create a ledger channel with the bridge on L1 which is mirrored on L2
* Run the following commands from the directory where the deployments are created
* Set required variables:
```bash
cd $DEPLOYMENTS_DIR/nitro-node
# Fetch the required Nitro node config
wget https://git.vdb.to/cerc-io/testnet-laconicd-stack/raw/branch/main/ops/stage2/nitro-node-config.yml
export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml)
export L1_ASSET_ADDRESS=$(yq eval '.l1_asset_address' nitro-node-config.yml)
```
* Check that check that you have no existing channels on L1 or L2:
```bash
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
# Expected output:
# []
```
* Create a ledger channel between your L1 Nitro node and Bridge with custom asset:
```bash
# Set amount to ledger
LEDGER_AMOUNT=1000000
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client direct-fund $BRIDGE_NITRO_ADDRESS --assetAddress $L1_ASSET_ADDRESS --alphaAmount $LEDGER_AMOUNT --betaAmount $LEDGER_AMOUNT -p 4005 -h nitro-node"
# Follow your L1 Nitro node logs for progress
# Expected Output:
# Objective started DirectFunding-0x161d289a50222caa781db215bb82a3ede4f557217742245525b8e8cbff04ec21
# Channel Open 0x161d289a50222caa781db215bb82a3ede4f557217742245525b8e8cbff04ec21
# Set the resulting ledger channel id in a variable
export LEDGER_CHANNEL_ID=
```
* Check the [Troubleshooting](#troubleshooting) section if command to create a ledger channel fails or gets stuck
* Once direct-fund objective is complete, the bridge will create a mirrored channel on L2
* Check L2 Nitro node's logs to see that a bridged-fund objective completed:
```bash
laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f --tail 30

* Check status of L1 ledger channel with the bridge using channel id:
```bash
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-ledger-channel $LEDGER_CHANNEL_ID -p 4005 -h nitro-node"
# Expected output:
# {
# ID: '0x161d289a50222caa781db215bb82a3ede4f557217742245525b8e8cbff04ec21',
# Status: 'Open',
# Balance: {
# AssetAddress: '<l1-asset-address>',
# Me: '<your-nitro-address>',
# Them: '<bridge-nitro-address>',
# MyBalance: <ledger-amount>n,
# TheirBalance: <ledger-amount>n
# },
# ChannelMode: 'Open'
# }
```
* Check status of the mirrored channel on L2:
```bash
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
# Expected output:
# [
# {

# "Status": "Open",
# "Balance": {
# "AssetAddress": "<l2-asset-address>",
# "Me": "<your-nitro-address>",
# "Them": "<bridge-nitro-address>",
# "MyBalance": <ledger-amount>n,
# "TheirBalance": <ledger-amount>n
# },
# "ChannelMode": "Open"
# }
# ]
```
## Clean up
* Switch to deployments dir:
```bash
cd $DEPLOYMENTS_DIR/nitro-node
```
* Stop all Nitro services running in the background:
```bash
laconic-so deployment --dir l1-nitro-deployment stop
laconic-so deployment --dir l2-nitro-deployment stop
```
* To stop all services and also delete data:
```bash
laconic-so deployment --dir l1-nitro-deployment stop --delete-volumes
laconic-so deployment --dir l2-nitro-deployment stop --delete-volumes
# Remove deployment directories (deployments will have to be recreated for a re-run)
sudo rm -r l1-nitro-deployment
sudo rm -r l2-nitro-deployment
```
## Troubleshooting
* Stop (`Ctrl+C`) the direct-fund command if it is stuck
* Restart the L1 Nitro node:
* Stop the deployment:
```bash
cd $DEPLOYMENTS_DIR/nitro-node
laconic-so deployment --dir l1-nitro-deployment stop
```
* Reset the node's durable store:
```bash
sudo rm -rf l1-nitro-deployment/data/nitro_node_data
mkdir l1-nitro-deployment/data/nitro_node_data
```
* Restart the deployment:
```bash
laconic-so deployment --dir l1-nitro-deployment start
```
* Retry the ledger channel creation command
