Convert a Subnet to an L1

The node you have just launched is tracking the Subnet but is not yet a validator. In fact, since the Subnet does not have any validators yet it cannot process any transactions. In this step we will do two things at once:

1. Convert the Subnet to an L1
2. Add your node as a validator

Converting a Subnet to an L1 requires the Subnet owner issuing a ConvertSubnetToL1Tx transaction on the P-Chain. This transaction establishes a new validator set for your blockchain and transforms it from a Subnet into a sovereign L1 chain. The ConvertSubnetToL1Tx transaction is a one-time transaction that can only be executed once by the Subnet owner(s).

After the conversion the subnet owner looses all privileges and the L1 is controlled by a validator manager contract, that manages the validator set. You will learn more about this in the next chapter.

The ConvertSubnetToL1Tx has the following parameters:

• Subnet ID - The unique identifier of your Subnet
• Validator Manager Blockchain ID - The ID of the blockchain where the Validator Manager contract will be deployed. This blockchain can belong to the L1, be the C-Chain or belong to any other L1 in the Avalanche network
• Validator Manager Address - The address of the contract on that blockchain
• Validators - The initial set of validators for the L1

Conversion Tool

Use the following tool to convert your Subnet to an L1:
