```
|
|
|
|
* 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 (under your user)
|
|
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
|
|
|
|
Nitro nodes can be run using Ansible either locally or on a remote machine; follow corresponding steps for your setup
|
|
|
|
### 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
|
|
|
|
* In `testnet-ops/nitro-nodes-setup`, 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
|
|
[<deployment_host>]
|
|
<host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
|
|
```
|
|
|
|
* Replace `<deployment_host>` with `nitro_host`
|
|
* 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
|
|
|
|
# If using password based authentication, enter the ssh password on prompt; otherwise, leave it blank
|
|
|
|
# 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
|
|
|
|
# If using password based authentication, enter the ssh password on prompt; otherwise, leave it blank
|
|
# Enter the sudo password as "BECOME password" on prompt
|
|
```
|
|
|
|
### Check Deployment Status
|
|
|
|
* Run the following commands on deployment machine:
|
|
|
|
```bash
|
|
DEPLOYMENTS_DIR=<path-to-deployments-dir>
|
|
|
|
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
|
|
|
|
# Let L1 node sync up with the chain
|
|
# Expected logs after sync:
|
|
# nitro-node-1 | 2:04PM INF Initializing Http RPC transport...
|
|
# nitro-node-1 | 2:04PM INF Completed RPC server initialization url=127.0.0.1:4005/api/v1
|
|
```
|
|
|
|
* Get your Nitro node's info:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-node-info -p 4005 -h nitro-node"
|
|
|
|
# Expected output:
|
|
# {
|
|
# "SCAddress": "0xd0eA8b27591b1D070cCcD4D30b8D408fe794FDfc",
|
|
# "MessageServicePeerId": "16Uiu2HAmSHRjoxveaPmJipzmdq69U8zme8BMnFjSBPferj1E5XAd"
|
|
# }
|
|
|
|
# SCAddress -> nitro address, MessageServicePeerId -> libp2p peer id
|
|
```
|
|
|
|
## Create Channels
|
|
|
|
Create a ledger channel with the bridge on L1 which is mirrored on L2
|
|
|
|
* Run the following commands on deployment machine
|
|
|
|
* Set required variables:
|
|
|
|
```bash
|
|
DEPLOYMENTS_DIR=<path-to-deployments-dir>
|
|
|
|
cd $DEPLOYMENTS_DIR/nitro-node
|
|
|
|
export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml)
|
|
|
|
# Get asset addresses from assets.json file
|
|
export ASSET_ADDRESS_1=$(jq -r --arg chainId "$CHAIN_ID" '.[$chainId][0].contracts.TestToken.address' assets.json)
|
|
export ASSET_ADDRESS_2=$(jq -r --arg chainId "$CHAIN_ID" '.[$chainId][0].contracts.TestToken2.address' assets.json)
|
|
```
|
|
|
|
* 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
|
|
laconic-so deployment --dir l1-nitro-deployment exec nitro-rpc-client "nitro-rpc-client direct-fund $BRIDGE_NITRO_ADDRESS --asset "$ASSET_ADDRESS_1:1000,1000" --asset "$ASSET_ADDRESS_2:1000,1000" -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
|
|
|
|
# Expected Output:
|
|
# nitro-node-1 | 5:01AM INF INFO Objective cranked address=0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce objective-id=bridgedfunding-0x6a9f5ccf1fa802525d794f4a899897f947615f6acc7141e61e056a8bfca29179 waiting-for=WaitingForNothing

|
|
```
|
|
|
|
* 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"
|
|

## Payments On L2 Channel
|
|
|
|
Perform payments using a virtual payment channel created with another Nitro node over the mirrored L2 channel with bridge as an intermediary
|
|
|
|
* Prerequisite: Ledger channel is required to create a payment channel
|
|
|
|
* Note: Currently payment channel is created from first asset present in ledger channel
|
|
|
|
* Run the following commands on deployment machine
|
|
|
|
* Switch to the `nitro-node` directory:
|
|
|
|
```bash
|
|
DEPLOYMENTS_DIR=<path-to-deployments-dir>
|
|
|
|
cd $DEPLOYMENTS_DIR/nitro-node
|
|
```
|
|
|
|
* Check status of the mirrored channel on L2:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-all-ledger-channels -p 4005 -h nitro-node"
|
|
|
|
# Example output:
|
|
# [
|
|
# {
|
|
# "ID": "0xb34210b763d4fdd534190ba11886ad1daa1e411c87be6fd20cff74cd25077c46",
|
|
# "Status": "Open",
|
|
# "Balances": [
|
|
# {
|
|
# "AssetAddress": "0xa4351114dae1abeb2d552d441c9733c72682a45d",
|
|
# "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05",
|
|
# "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185",
|
|
# "MyBalance": 1000,
|
|
# "TheirBalance": 1000
|
|
# },
|
|
# {
|
|
# "AssetAddress": "0x314e43f9825b10961859c2a62c2de6a765c1c1f1",
|
|
# "Me": "0x075400039e303b3fb46c0cff0404c5fa61947c05",
|
|
# "Them": "0xf0e6a85c6d23aca9ff1b83477d426ed26f218185",
|
|
# "MyBalance": 1000,
|
|
# "TheirBalance": 1000
|
|
# }
|
|
# ],
|
|
# "ChannelMode": "Open"
|
|
# }
|
|
# ]
|
|
```
|
|
|
|
* Set required variables:
|
|
|
|
```bash
|
|
export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml)
|
|
|
|
# Counterparty to create the payment channel with
|
|
export COUNTER_PARTY_ADDRESS=<counterparty-nitro-address>
|
|
|
|
# Mirrored channel on L2
|
|
export L2_CHANNEL_ID=<l2-channel-id>
|
|
|
|
# Amount to create the payment channel with
|
|
export PAYMENT_CHANNEL_AMOUNT=500
|
|
```
|
|
|
|
* Check for existing payment channels for the L2 channel:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-payment-channels-by-ledger $L2_CHANNEL_ID -p 4005 -h nitro-node"
|
|
```
|
|
|
|
* Create a virtual payment channel:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-fund $COUNTER_PARTY_ADDRESS $BRIDGE_NITRO_ADDRESS --amount $PAYMENT_CHANNEL_AMOUNT -p 4005 -h nitro-node"
|
|
|
|
# Follow your L2 Nitro node logs for progress
|
|
|
|
# Expected Output:
|
|
# Objective started VirtualFund-0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d
|
|
# Channel Open 0x43db45a101658387263b36d613322cc952d8ce5b70de51e3a495513c256bef4d
|
|
|
|
# Set the resulting payment channel id in a variable
|
|
PAYMENT_CHANNEL_ID=<payment-channel-id>
|
|
```
|
|
|
|
Multiple virtual payment channels can be created at once
|
|
|
|
* Check the payment channel's status:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-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: '<your-nitro-address>',
|
|
# Payer: '<counterparty-nitro-address>',
|
|
# PaidSoFar: 0n,
|
|
# RemainingFunds: <payment-channel-amount>n
|
|
# }
|
|
# }
|
|
```
|
|
|
|
* Send payments using the virtual payment channel:
|
|
|
|
```bash
|
|
export PAY_AMOUNT=200
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client pay $PAYMENT_CHANNEL_ID $PAY_AMOUNT -p 4005 -h nitro-node"
|
|
|
|
# Expected output
|
|
# {
|
|
# Amount: <pay-amount>,

|
|
```
|
|
|
|
* Check payment channel's status again to view updated channel state
|
|
|
|
* Close the payment channel to settle on the L2 mirrored channel:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client virtual-defund $PAYMENT_CHANNEL_ID -p 4005 -h nitro-node"

Your balance on the L2 channel should be reduced by total payments done on the virtual payment channel
|
|
|
|
## Swaps on L2
|
|
|
|
Perform swaps using a swap channel created with another Nitro node over the mirrored L2 channel with bridge as an intermediary
|
|
|
|
* Prerequisite: Ledger channel is required to create a swap channel
|
|
|
|
* Run the following commands on deployment machine
|
|
|
|
* Switch to the `nitro-node` directory:
|
|
|
|
```bash
|
|
DEPLOYMENTS_DIR=<path-to-deployments-dir>
|
|
|
|
cd $DEPLOYMENTS_DIR/nitro-node
|
|
```
|
|
|
|
* 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"
|
|
|
|
# Example output:

|
|
# "ChannelMode": "Open"
|
|
# }
|
|
# ]
|
|
```
|
|
|
|
* Set required variables:
|
|
|
|
```bash
|
|
export BRIDGE_NITRO_ADDRESS=$(yq eval '.bridge_nitro_address' nitro-node-config.yml)
|
|
|
|
# Counterparty to create the swap channel with
|
|
export COUNTER_PARTY_ADDRESS=<counterparty-nitro-address>
|
|
|
|
# Get asset addresses from assets.json file
|
|
export ASSET_ADDRESS_1=$(jq -r --arg chainId "$CHAIN_ID" '.[$chainId][0].contracts.TestToken.address' assets.json)
|
|
export ASSET_ADDRESS_2=$(jq -r --arg chainId "$CHAIN_ID" '.[$chainId][0].contracts.TestToken2.address' assets.json)
|
|
```
|
|
|
|
* Create swap channel:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client swap-fund $COUNTER_PARTY_ADDRESS $BRIDGE_NITRO_ADDRESS --asset "$ASSET_ADDRESS_1:100,100" --asset "$ASSET_ADDRESS_2:100,100" -p 4005 -h nitro-node"

### Performing swaps
|
|
|
|
* One of the participants can initiate the swap and other one will either accept it or reject it
|
|
|
|
* For initiating the swap:
|
|
|
|
```bash
|
|
laconic-so deployment --dir l2-nitro-deployment exec nitro-rpc-client "nitro-rpc-client swap-initiate $SWAP_CHANNEL_ID --AssetIn "$ASSET_ADDRESS_1:20" --AssetOut "$ASSET_ADDRESS_2:10" -p 4005 -h nitro-node"
|
|
|
|
# Expected output:

## 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
|
|
|
|
* Check the logs of nitro node to see if the objective is completed
|
|
|
|
```bash
|
|
# To check logs of L1 nitro-node
|
|
laconic-so deployment --dir l1-nitro-deployment logs nitro-node -f --tail 30
|
|
|
|
# To check logs of L2 nitro-node
|
|
laconic-so deployment --dir l2-nitro-deployment logs nitro-node -f --tail 30
|
|
```
|
|
|
|
* If the objective is completed, you can safely stop (`Ctrl+C`) the running CLI command and continue with the further instructions
|
|
|
|
* 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
|
