<summary>Fixturenet Eth</summary>
## Fixturenet Eth
* Stack: <https://git.vdb.to/cerc-io/fixturenet-eth-stacks>
* Target dir: `/srv/fixturenet-eth/fixturenet-eth-deployment`
* Cleanup an existing deployment if required:
```bash
cd /srv/fixturenet-eth
# Stop the deployment
laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes
# Remove the deployment dir
sudo rm -rf fixturenet-eth-deployment
```
### Setup
* Create a `fixturenet-eth` dir if not present already and cd into it
```bash
mkdir /srv/fixturenet-eth
cd /srv/fixturenet-eth
```
* Clone the stack repo:
```bash
laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-eth-stacks --pull
```
* Clone required repositories:
```bash
laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth 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
laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth 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
```
* Configure ports:
* `fixturenet-eth-spec.yml`
```yml
...
network:
ports:
fixturenet-eth-bootnode-geth:
- '9898:9898'
- '30303'
fixturenet-eth-geth-1:
- '7545:8545'
- '7546:8546'
- '40000'
- '6060'
fixturenet-eth-lighthouse-1:
- '8001'
...
```
* 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
```
### Run
* Start `fixturenet-eth-deployment` deployment:
```bash
laconic-so deployment --dir fixturenet-eth-deployment start

# Nitro Token Ops
## Setup
* Go to the directory where `nitro-contracts-deployment` is present:
```bash
cd /srv/bridge
```
## Deploy new token
* To deploy another token:
```bash
# These values can be changed to deploy another token with different name and symbol
export TOKEN_NAME="TestToken2"
export TOKEN_SYMBOL="TST2"
# Note: Token supply denotes actual number of tokens and not the supply in Wei
export INITIAL_TOKEN_SUPPLY="129600"
laconic-so deployment --dir nitro-contracts-deployment exec nitro-contracts "TOKEN_NAME=$TOKEN_NAME TOKEN_SYMBOL=$TOKEN_SYMBOL INITIAL_TOKEN_SUPPLY=$INITIAL_TOKEN_SUPPLY /app/deploy-l1-tokens.sh"

* Recreate `assets.json` to include newly deployed token address:
```bash

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"

### 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:

# }
```
OR
* For receiving the swap
* Get the pending swap:
```bash
