# Launching an L1 Devnet / Testnet

To launch your Avalanche L1 Devnet or Testnet, the first step is to subscribe to the desired network tier through our platform. Once the subscription is active, you can proceed with configuring your network by providing essential details such as chain parameters, tokenomics settings, and permission for native precompiles. 

This setup ensures your environment is tailored to your specific use case. The platform guides you through each step, making it seamless to deploy and manage your own sovereign EVM-compatible chain.
