Local devnet setup

This guide covers how to set up a local devnet with both consensus and bridge nodes for development and testing purposes. A local devnet allows you to run a complete Celestia network environment on your local machine.

Choose your setup method

Pick the approach you want to follow:

Default endpoints

Once your local devnet is running, you can access these endpoints:

Multi-validator private networks (not local-only)

This page focuses on a single-machine devnet. If you instead want to create a private testnet across multiple machines/participants (genesis + gentx flow), start from:

• Signing genesis for a new network
• Optional: Set persistent peers

Next steps

With your local devnet running, you can:

• Submit blob data
• Test rollup integrations
• Develop applications using the Celestia Node API
• Practice validator operations without risking real tokens
