How to Deploy Teleporter Enabled Subnets on a Local Network

This how-to guide focuses on deploying Teleporter-enabled Subnets to a local Avalanche network.

After this tutorial, you would have created and deployed two Subnets to the local network and have enabled them to cross-communicate with each other and with the local C-Chain (through Teleporter and the underlying Warp technology.)

For more information on cross chain messaging through Teleporter and Warp, check:

Note that currently only Subnet-EVM and Subnet-EVM-Based virtual machines support Teleporter.

Prerequisites​

Create Subnet Configurations​

Let's create a Subnet called <subnet1> with the latest Subnet-EVM version, a chain ID of 1, TOKEN1 as the token name, and with default Subnet-EVM parameters (more information regarding Subnet creation can be found here):

avalanche subnet create <subnet1> --evm --latest\
--evm-chain-id 1 --evm-token TOKEN1 --evm-defaults

creating genesis for <subnet subnet1>
configuring airdrop to stored key "subnet_<subnet1>_airdrop" with address 0x0EF8151A3e6ad1d4e17C8ED4128b20EB5edc58B1
loading stored key "cli-teleporter-deployer" for teleporter deploys
(evm address, genesis balance) = (0xE932784f56774879e03F3624fbeC6261154ec711, 600000000000000000000)
using latest teleporter version (v1.0.0)
✓ Successfully created subnet configuration

Notice that by default, Teleporter is enabled and a stored key is created to fund Teleporter related operations (that is deploy Teleporter smart contracts, fund Teleporter Relayer).

To disable Teleporter in your Subnet, use the flag --teleporter=false when creating the Subnet.

To disable Relayer in your Subnet, use the flag --relayer=false when creating the Subnet.

Now let's create a second Subnet called <subnet2>, with similar settings:

avalanche subnet create <subnet2> --evm --latest\
--evm-chain-id 2 --evm-token TOKEN2 --evm-defaults

creating genesis for <subnet subnet2>
configuring airdrop to stored key "subnet_<subnet2>_airdrop" with address 0x0EF815FFFF6ad1d4e17C8ED4128b20EB5edAABBB
loading stored key "cli-teleporter-deployer" for teleporter deploys
(evm address, genesis balance) = (0xE932784f56774879e03F3624fbeC6261154ec711, 600000000000000000000)
using latest teleporter version (v1.0.0)
✓ Successfully created subnet configuration

Deploy the Subnets to Local Network​

Let's deploy <subnet1>:

avalanche subnet deploy <subnet1> --local

Notice some details here:

  • Two smart contracts are deployed to each Subnet: Teleporter Messenger and Teleporter Registry
  • Both Teleporter smart contracts are also deployed to C-Chain in the Local Network
  • AWM Teleporter Relayer is installed, configured and executed in background (A Relayer listens for new messages being generated on a source Subnet and sends them to the destination Subnet.)

CLI configures the Relayer to enable every Subnet to send messages to all other Subnets. If you add more Subnets, the Relayer will be automatically reconfigured.

When deploying Subnet <subnet2>, the two Teleporter contracts will not be deployed to C-Chain in Local Network as they have already been deployed when we deployed the first Subnet.

avalanche subnet deploy <subnet2> --local

Verify Teleporter Is Successfully Set Up​

To verify that Teleporter is successfully, let's send a couple of cross messages:

avalanche teleporter msg C-Chain subnet1 "Hello World" --local

Delivering message "this is a message" to source subnet "C-Chain"
Waiting for message to be received at destination subnet subnet "subnet1"
Message successfully Teleported!
avalanche teleporter msg subnet2 subnet1 "Hello World" --local

Delivering message "this is a message" to source subnet "subnet2"
Waiting for message to be received at destination subnet subnet "subnet1"
Message successfully Teleported!

You have Teleport-ed your first message in the Local Network!

Relayer related logs can be found at ~/.avalanche-cli/runs/awm-relayer.log, and Relayer configuration can be found at ~/.avalanche-cli/runs/awm-relayer-config.json

Obtaining Subnet Information​

By executing subnet describe on a Teleporter enabled Subnet, the following relevant information can be found:

  • Blockchain RPC URL
  • Blockchain ID in cb58 format
  • Blockchain ID in plain hex format
  • Teleporter Messenger address
  • Teleporter Registry address

Let's get the information for <subnet1>:

Controlling Relayer Execution​

Besides having the option to not use a Relayer at Subnet creation time, the Relayer can be stopped and restarted on used request.

To stop the Relayer:

avalanche teleporter relayer stop --local

✓ Local AWM Relayer successfully stopped

To start it again:

avalanche teleporter relayer start --local

using latest awm-relayer version (v1.1.0)
Executing AWM-Relayer...
✓ Local AWM Relayer successfully started
