Why Deploy a Custom Rollup on Celestia?

Celestia is at the forefront of modular blockchain architecture, offering a dedicated data availability layer that decouples consensus from execution. By deploying your rollup on Celestia, you unlock significant scalability, lower transaction costs, and flexible settlement options. Integrating with Conduit further reduces operational overhead, allowing you to deploy in minutes instead of weeks.

The modular approach means you can choose your preferred execution environment (such as OP Stack or Arbitrum Orbit), select a settlement layer (Ethereum, Base, Zora, or Mode), and rely on Celestia for efficient data availability. This flexibility is driving adoption from teams like Aevo and Lyra, who’ve already migrated to Celestia for its cost savings and performance gains.

Step-by-Step: Starting Your Rollup Deployment

Let’s walk through the essential steps for deploying a custom rollup on Celestia using the Conduit framework. The process is permissionless and streamlined, making it possible to go from concept to mainnet in under 15 minutes.

Access the Conduit App and Log In
Begin by navigating to the Conduit application in your web browser. Log in with your credentials or create an account if you’re new. Once logged in, locate and click the 'Deploy a Rollup' button to start the deployment process.
A web form with fields for 'Rollup Name', 'Chain ID', dropdowns for 'Framework', 'Settlement Layer', and 'Data Availability Layer', with 'Celestia' highlighted.
Configure Your Rollup Details
Enter a unique name for your rollup and select a chain ID, ensuring it’s not already in use by checking resources like Chainlist. Next, choose your preferred rollup framework (e.g., OP Stack or Arbitrum Orbit), pick a settlement layer (such as Ethereum, Base, Zora, or Mode), and select Celestia as your data availability layer. For a live deployment, set the environment to 'Mainnet'.

Add Billing Details and Fund the Deployer Wallet
Input your credit card information to cover the subscription costs. If you have a promotional code, apply it now. Next, ensure your deployer wallet is funded to pay for deployment expenses. You can connect an existing wallet or transfer funds to the provided address. This step is crucial to proceed with the deployment.

Initiate and Monitor the Deployment
After completing the configuration and funding steps, initiate the deployment. The Conduit platform will handle the process, and you can monitor progress through a real-time dashboard. Deployment typically completes in about 15 minutes. Once live, your rollup is ready for application development and scaling.
  1. Access the Conduit App: Visit the Conduit application and log in with your credentials. Click ‘Deploy a Rollup’ to begin.
  2. Configure Rollup Details: Enter a unique rollup name and choose a chain ID (double-check against Chainlist to avoid conflicts). Decide on your tech stack (OP Stack, Arbitrum Orbit), settlement layer, and select Celestia as the data availability layer. For production, pick the ‘Mainnet’ environment.
  3. Billing and Funding: Add your billing details (credit card or promo code) and ensure the deployer wallet has enough funds for deployment fees. You can connect an existing wallet or transfer funds to the provided address.
  4. Launch: Review your configuration and hit ‘Deploy’. The system will provision your rollup, handle infrastructure, and provide you with endpoints once live.

After your rollup is deployed, the real power of modular architecture comes into play. With Conduit and Celestia, you’re not locked into rigid templates. You can fine-tune everything from gas parameters to whitelisting contracts, sequencer rotation, and even integrate custom execution logic. This is where the flexibility of a modular stack shines, whether you want to enable new settlement options or experiment with Layer 3 (L3) configurations for ultra-low fees, the stack is yours to shape.

For developers looking to push boundaries, Celestia’s data availability layer offers robust support for scaling dApps and experimenting with novel rollup architectures. You can also leverage Conduit’s managed infrastructure to automate upgrades, monitor performance, and respond to network events without manual intervention.

Monitoring and Scaling: Best Practices

Managing your rollup post-deployment is critical for reliability and growth. Conduit provides a unified dashboard for tracking uptime, throughput, and transaction metrics. Set up alerts for sequencer downtime or unusual activity to keep your network healthy. For scaling, consider these best practices:

  • Regularly review chain metrics: Monitor block times, gas usage, and transaction throughput to identify bottlenecks.
  • Upgrade proactively: Take advantage of managed upgrades from Conduit to stay compatible with evolving frameworks.
  • Community engagement: Foster a developer community around your rollup, open-source modules and documentation can accelerate adoption.
