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 command in intervals of 3 seconds to check if new blocks are created

          laconic-so deployment --dir fixturenet-eth-deployment exec foundry "cast block-number"
          
        • 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

      • 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

        • 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

    • Connect to the testnet-onboarding app by clicking on the WalletConnect icon on the top right corner in the wallet and scanning QR code of the 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
    • Fund the laconic account by clicking on the REQUEST TOKENS FROM FAUCET button

    • Send transaction request to the 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 1 (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

Payments Demo in L2

  • Create virtual channel on L2 from A' to C' via Bridge' as intermediary

  • After running demo cleanup, follow the steps from Demo to re-run the demo

Cleanup

  • Reset nitro-node deployments:

    • Stop nitro-node deployments and remove volumes:

      # 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-node and bridge deployments:

      # 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
      
  • Reset wallet and stop the app:

    • In laconic-wallet, click on the Reset Wallet button to disconnect all apps and clear the accounts

    • Stop (Ctrl+C) both laconic-wallet and testnet-onboarding-app

  • Clean up stage 0 and stage 1 laconicd deployments:

    • Stop deployment and remove volumes:

      # Run where deployments are created
      laconic-so deployment --dir stage0-deployment stop --delete-volumes
      laconic-so deployment --dir stage1-deployment stop --delete-volumes
      
    • Clear deployments:

      # Run where deployments are created
      sudo rm -rf stage0-deployment
      sudo rm -rf stage1-deployment
      
  • Clean up faucet deployment:

    • Stop deployment and remove volumes:

      laconic-so deployment --dir laconic-faucet-deployment stop --delete-volumes
      
    • Clear deployment

      # Run where deployment is created
      sudo rm -rf laconic-faucet-deployment
      
  • Clean up L1 and L2 deployments:

    • Stop deployment and remove volumes:

      # 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:

      # 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.

      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
