How to View and Delete Your Created Subnets

This tutorial covers how to view and delete subnets in Avalanche network. It provides commands for listing subnets, describing a specific subnet and deleting a subnet. To list subnets, the command avalanche subnet list can be used. To see detailed information about a subnet, the command avalanche subnet describe <subnetName> can be used. To delete a subnet, the command avalanche subnet delete <subnetName> can be used.

List Subnet Configurations​

You can list the Subnets you’ve created with

avalanche subnet list

Example:

> avalanche subnet list
+-------------+-------------+----------+---------------------------------------------------+------------+-----------+
|   SUBNET    |    CHAIN    | CHAIN ID |                       VM ID                       |    TYPE    | FROM REPO |
+-------------+-------------+----------+---------------------------------------------------+------------+-----------+
| test        | test        |     5234 | tGBrM2SXkAdNsqzb3SaFZZWMNdzjjFEUKteheTa4dhUwnfQyu | Subnet-EVM | false     |
+-------------+-------------+----------+---------------------------------------------------+------------+-----------+

To see detailed information about your deployed Subnets, add the --deployed flag:

> avalanche subnet list --deployed

Describe Subnet Configurations​

To see the details of a specific configuration, run

avalanche subnet describe <subnetName>

Example:

> avalanche subnet describe firstsubnet

Viewing a Genesis File​

If you’d like to see the raw genesis file, supply the --genesis flag to the describe command:

avalanche subnet describe <subnetName> --genesis

Deleting a Subnet Configuration​

To delete a created Subnet configuration, run

avalanche subnet delete <subnetName>

Deleting a Deployed Subnet​

You can’t delete Subnets deployed to Mainnet or the Fuji Testnet.

However, you may delete Subnets deployed to a local network by cleaning the network state with

avalanche network clean
