Configure Custom Native Tokens

Creating the Blockchain

Start by creating a new blockchain using the avalanche CLI tool:

avalanche blockchain create myblockchain

Select VM

You will be prompted to select the Subnet-EVM as the virtual machine for your blockchain:

? Which Virtual Machine would you like to use?: 
  ▸ Subnet-EVM
    Custom VM
    Explain the difference

Select Subnet-EVM to proceed.

Customizing Blockchain Configuration

After selecting Subnet-EVM, you’ll have the option to use default values or customize your blockchain settings:

? Do you want to use default values for the Blockchain configuration?: 
    I want to use defaults for a test environment
    I want to use defaults for a production environment
  ▸ I don't want to use default values
    Explain the difference

Select I don’t want to use default values to manually configure your blockchain.

Setting the Version, ChainID, and Token Symbol

Next, you will be asked to choose the version of Subnet-EVM and configure the ChainID and token symbol:

✔ Subnet-EVM
✔ I don't want to use default values
? Version: 
  ▸ Use latest release version
    Specify custom version

Choose Use latest release version for the Subnet-EVM. After that, you will configure the following:

✔ Chain ID: 123456
✔ Token Symbol: CNT

• ChainID: Choose a unique Chain ID that hasn’t been used on another blockchain. You can reference available Chain IDs by visiting ChainList, which lists in-use Chain IDs.

• Token Symbol: Set a token symbol for your custom native token (e.g., CNT). This symbol will represent your blockchain’s native token in transactions and applications.
