Create Your L1
Quick guide to creating a subnet and converting it to an L1 with required precompiles
This section provides a streamlined walkthrough for creating a new L1 from scratch.
You should already have a created L1 from the Permissioned L1 course with the Validator Manager Contract correctly set up that you can use to transform into a Permissionless L1. But just in case you lost access to that one or want to start fresh, this guide is for you!
Create Subnet with necessary Precompiles
When creating your subnet, you must enable the Native Minter and Reward Manager precompiles in your genesis configuration. These are essential for native token staking:
- Native Minter: Allows the staking manager to mint reward tokens
- Reward Manager: Automates reward distribution to validators
Set Up Validator Node
Launch a validator node for your subnet using our free managed testnet infrastructure (no Docker required):
Production & Extended Testing Environments
After creating nodes, you can view and manage them at the Testnet Infrastructure Console. Managed nodes automatically shut down after 3 days. For production or extended testing, see the self-hosted option below.
For production environments or extended testing periods, you should use Docker to run your nodes.
Convert Subnet to L1
Once your subnet is running with a validator, convert it to a sovereign L1. This process:
- Establishes Sovereignty: Your blockchain becomes independent
- Transfers Authority: Validator management shifts from P-Chain to your Validator Manager Contract
- Is Irreversible: Once converted, you cannot revert to subnet status
Key Conversion Parameters
- Subnet ID: Your subnet's unique identifier
- Validator Manager Blockchain ID: Where your VMC will be deployed (typically your L1)
- Validator Manager Address: The proxy address (pre-deployed to
0xfacade0000000000000000000000000000000000) - Initial Validators: The validator(s) from your subnet
Next Steps
Now that your L1 is created with the required precompiles, you're ready to deploy and configure your Validator Manager Contract so that it becomes a Permissioned L1.
