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

Run the bridge:

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"

Create a deployment from the spec file:

laconic-so --stack ~/cerc/nitro-stack/stack-orchestrator/stacks/bridge deploy create --spec-file bridge-nitro-spec.yml --deployment-dir bridge-deployment

Start the nitro bridge

laconic-so deployment --dir bridge-deployment start

# 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

export L1_ASSET_ADDRESS="$(laconic-so deployment --dir bridge-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"

Send tokens to Alice and Charlie

# Send tokens to Alice
laconic-so deployment --dir bridge-deployment exec nitro-contracts "cd packages/nitro-protocol && yarn hardhat transfer --contract $L1_ASSET_ADDRESS --to $A_CHAIN_ADDRESS --amount 1000 --network geth"

#Send tokens to Charlie
laconic-so deployment --dir bridge-deployment exec nitro-contracts "cd packages/nitro-protocol && yarn hardhat transfer --contract $L1_ASSET_ADDRESS --to $C_CHAIN_ADDRESS --amount 1000 --network geth"

Start onboarding-app and onboarding-api deployments (run where deployments are created):

# Builds and serves the app
laconic-so deployment --dir onboarding-app-deployment start

# Serves the API to generate access tokens
laconic-so deployment --dir onboarding-api-deployment start

Check the health status for onboarding-app container:

docker ps | grep testnet-onboarding-app

Once the container is healthy, the testnet-onboarding-app will be accessible at http://localhost:3000

Start nitro nodes for Alice and Charlie on L1 and L2:

Start the deployment for Alice's L1 node

laconic-so deployment --dir l1alice-nitro-deployment start

# Check the logs, ensure that the node is running
laconic-so deployment --dir l1alice-nitro-deployment logs nitro-node -f

Start the deployment for Charlie's L1 node

laconic-so deployment --dir l1charlie-nitro-deployment start

# Check the logs, ensure that the node is running
laconic-so deployment --dir l1charlie-nitro-deployment logs nitro-node -f

Start the deployment for Alice's L2 node

laconic-so deployment --dir l2alice-nitro-deployment start

# Check the logs, ensure that the node is running
laconic-so deployment --dir l2alice-nitro-deployment logs nitro-node -f

Start the deployment for Charlie's L2 node

laconic-so deployment --dir l2charlie-nitro-deployment start

# Check the logs, ensure that the node is running
laconic-so deployment --dir l2charlie-nitro-deployment logs nitro-node -f

Create ledger channels on L1 and mirrored channels on L2

Open new terminal, check that no channels exist on L2

laconic-so deployment --dir bridge-deployment exec nitro-rpc-client "nitro-rpc-client get-all-l2-channels -p 4005 -h nitro-bridge"

Set address of bridge and address of custom token on L1 in the current terminal

export BRIDGE_NITRO_ADDRESS=0xBBB676f9cFF8D242e9eaC39D063848807d3D1D94
export L1_ASSET_ADDRESS="$(laconic-so deployment --dir bridge-deployment exec nitro-contracts "jq -r '.\"1212\"[0].contracts.Token.address' /app/deployment/nitro-addresses.json")"

Create ledger channel between A and Bridge with custom token
```
laconic-so deployment --dir l1alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client direct-fund $BRIDGE_NITRO_ADDRESS --assetAddress $L1_ASSET_ADDRESS --alphaAmount 1000000 --betaAmount 1000000 -p 4005 -h nitro-node"
```
- Once direct-fund objective is complete, bridge will create mirrored channel on L2
- Check node A' logs to see bridged-fund objective completed
- Check the Troubleshooting section if command to create a ledger channel fails or gets stuck

Check status of L1 ledger channel between A and Bridge

laconic-so deployment --dir l1alice-nitro-deployment exec nitro-rpc-client "nitro-rpc-client get-ledger-channel <ledger channel ID> -p 4005 -h nitro-node"

In above expected output the following are observed

In ledger channel with ID 0x15dbe6b996e4e46fdd6ea3e2074cbca58014dbb07368e3e7ba286df5c7b9da0d
- Alice is a participant since Them address is 0xa8d2d06ace9c7ffc24ee785c2695678aecdfd7a0
- Alice amount is 1000000 since TheirBalance corresponds to her amount
In ledger channel with ID 0x6a9f5ccf1fa802525d794f4a899897f947615f6acc7141e61e056a8bfca29179
- Charlie is participant since Them address is 0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce
- Charlie amount is 1000000 since TheirBalance corresponds to his amount

Onboard participants
- Open the testnet-onboarding-app at http://localhost:3000
- Read and accept the Terms and Conditions
- Connect testnet-onboarding app to the wallet:
  - Click on CONNECT WALLET button on the testnet-onboarding app
  - Click on the WalletConnect icon on the top right corner in the wallet
    - If using the wallet Android app, scan the QR code from the onboarding app
    - If using the wallet website, enter WalletConnect URI for pairing
- In the onboarding app, choose Alice's nitro and laconicd account to onboard
  - Use nitro accounts for which ledger channels have been created on L2
- Sign using the nitro key
  - Approve sign request on Wallet
- Perform the user verification steps
- Select the desired participant role (Validator or Participant) and accept the onboarding terms and conditions
- In the next step, fund your laconic account by clicking on the REQUEST TOKENS FROM FAUCET button; ensure that the displayed balance is updated
- Send transaction request to the wallet
  - From wallet, approve and send transaction to laconicd chain
- Repeat onboarding for other (Charlies's) account by clicking on the web app header "Testnet Onboarding"
- List the participants on stage 0 (run in the directory where laconicd deployment was created):
```
laconic-so deployment --dir stage0-deployment exec laconicd "laconicd query onboarding list"

# Expected output
# - cosmos_address: <Alice Laconic address>
#   ethereum_address: <Alice Ethereum address>
# - cosmos_address: <Charlie Laconic address>
#   ethereum_address: <Charlie Ethereum address>
```
- Halt the stage 0 laconicd deployment:
```
# Run where deployments are created
laconic-so deployment --dir stage0-deployment stop
```
- Use the scripts in fixturenet-laconicd stack to generate genesis file for stage 1 with token allocations:
```
# Set current working dir path in a variable
DEPLOYMENTS_DIR=$(pwd)

cd ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd

# Fetch account holdings from bridge
./scripts/fetch-account-holdings.sh $DEPLOYMENTS_DIR/bridge-deployment eth-account-holdings.json

# Generate the genesis file
./scripts/generate-stage1-genesis.sh $DEPLOYMENTS_DIR/stage0-deployment eth-account-holdings.json

# Expected output:
# Genesis file for stage1 written to output/genesis.json

# Remove the temporary data directory
sudo rm -rf stage1-genesis

# Go back to the directory where deployments are created
cd -
```
- Copy over the generated genesis file (.json) containing the onboarding module state with funded participants to data directory in stage1 deployment (stage1-deployment/data/genesis-config):
```
# Run where deployments are created
cp ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd/output/genesis.json stage1-deployment/data/genesis-config/genesis.json
```
- Start the deployment for stage 1
```
laconic-so deployment --dir stage1-deployment start
```
- The bank module transfers are disabled on stage 1 laconicd
- Query the list of registered participants in stage 1 laconicd:
```
laconic-so deployment --dir stage1-deployment exec laconicd "laconicd query onboarding list"

# Expected output: same as the result from stage0-deployment
```
- Query the balances of registered participants:
```
export A_LACONIC_ADDRESS=<Alice Laconic address>
export C_LACONIC_ADDRESS=<Charlie Laconic address>

laconic-so deployment --dir stage1-deployment exec laconicd "laconicd query bank balances $A_LACONIC_ADDRESS"

laconic-so deployment --dir stage1-deployment exec laconicd "laconicd query bank balances $C_LACONIC_ADDRESS"

# Expected output: Account balances equal to Alice's and Charlie's holdings on the bridge
```
- The bridge holdings are therefore reflected on stage 1 laconicd chain as genesis allocations
- TODO: The registered participants with balances on stage 1 laconicd chain can join as validators
  - https://git.vdb.to/cerc-io/laconic-testnet/src/branch/main/validator.md

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:

export A_ADDRESS=<Alice Nitro address>
export C_ADDRESS=<Charlie Nitro address>

# Bridge's Nitro address
export BRIDGE_NITRO_ADDRESS=0xBBB676f9cFF8D242e9eaC39D063848807d3D1D94

Create a virtual channel:

# 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'

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

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

Close payment channel after payments

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:

Troubleshooting

If the ledger channel creation fails, follow these steps:
- Check whether the status of cerc/fixturenet-eth-geth is unhealthy.
```
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
