Building EVM-Compatible Rollups on Eclipse: A Developer’s Tutorial

For developers eager to harness both Ethereum’s robust smart contract ecosystem and the performance of Solana, Eclipse offers a compelling solution. As a modular rollup platform, Eclipse enables you to build EVM-compatible rollups with unprecedented flexibility. Whether you’re migrating an existing dApp or starting from scratch, Eclipse’s architecture lets you tailor execution environments and data availability layers to your project’s precise needs.

Why Build EVM-Compatible Rollups on Eclipse?

The blockchain landscape is evolving toward modularity, where execution, settlement, and data availability are decoupled for optimal efficiency and scalability. Eclipse sits at the forefront of this movement. By supporting both the Ethereum Virtual Machine (EVM) and Solana Virtual Machine (SVM), it bridges two thriving ecosystems. For EVM developers, this means you can deploy Solidity-based contracts using familiar tools like Hardhat while benefiting from customizable infrastructure choices.

Eclipse’s unique value proposition:

• Flexibility: Choose your own execution environment (EVM or SVM) and data availability layer (Celestia, Polygon Avail, etc. ).
• Performance: Leverage Solana-inspired throughput while retaining Ethereum compatibility.
• Interoperability: Shared settlement layers foster seamless cross-rollup communication.
• Security: Rely on Ethereum’s robust security guarantees by settling transactions on its mainnet.

If you’re curious about how these components interact in practice, see the official documentation for more technical details: Eclipse Developer Guides.

The Modular Stack: Key Choices for Your Rollup

Your first decision when building an EVM-compatible rollup on Eclipse is selecting the right execution environment. Opting for EVM ensures compatibility with existing Ethereum dApps and tooling. Next comes picking a data availability layer - Celestia and Polygon Avail are popular choices for their scalability and decentralization.

Key Components to Launch an EVM Rollup on Eclipse

1. 

   EVM Execution Environment: Select the Ethereum Virtual Machine (EVM) as your execution environment to ensure compatibility with Solidity smart contracts and popular Ethereum developer tools like Hardhat and Remix.
2. 

   Data Availability Layer: Choose a robust data availability solution such as Celestia or Polygon Avail to ensure transaction data is securely stored and accessible.
3. 

   Settlement Layer: Configure Eclipse's shared settlement layer to facilitate interoperability and finalize transactions across different rollups on the platform.
4. 

   Rollup Deployment Tools: Utilize established toolkits like Rollkit for deploying and managing your rollup, and leverage Eclipse's official documentation for step-by-step guidance.
5. 

   Testing and Monitoring Infrastructure: Set up comprehensive testing using frameworks such as Hardhat or Foundry, and monitor your rollup's performance with analytics tools to ensure reliability and security.

The shared settlement layer provided by Eclipse is what enables interoperability between different rollups within its ecosystem. This architecture also opens the door for cross-chain applications powered by IBC (Inter-Blockchain Communication), further expanding your project’s reach.

Step-by-Step: Configuring Your First EVM Rollup

The process of launching your own EVM-compatible rollup on Eclipse can be broken down into four core steps:

1. Select Execution Environment: Choose the EVM to ensure Solidity support and access to the vast Ethereum developer toolkit.
2. Pick Data Availability Layer: Evaluate options like Celestia or Polygon Avail based on cost, throughput, and decentralization needs (more details here).
3. Configure Settlement Layer: Use Eclipse’s default shared settlement infrastructure for easy interoperability between your rollup and others in the ecosystem.
4. Deploy and Test: Launch your rollup in a testnet environment using familiar tools such as Hardhat or Truffle. Conduct rigorous testing before moving to mainnet deployment (see Rollkit's tutorial).

This modular approach empowers teams to optimize each layer according to their application’s requirements - whether that means maximizing throughput, minimizing costs, or prioritizing composability across chains.

As you complete these foundational steps, the real power of Eclipse’s modularity becomes apparent. Unlike monolithic chains, Eclipse lets you iterate quickly, swap components as your needs evolve, and plug into a growing network of interoperable rollups. This is especially useful for projects aiming to future-proof their infrastructure or experiment with emerging data availability solutions.

Deploying and Testing a Solidity Smart Contract on Eclipse EVM Rollup

Set Up Your Development Environment

Begin by installing essential tools such as Node.js, npm, and Hardhat. These will allow you to write, compile, and deploy Solidity smart contracts. Ensure your environment is configured for EVM compatibility to match Eclipse's requirements.

Connect to the Eclipse EVM Rollup Testnet

Obtain the RPC endpoint for the Eclipse EVM rollup testnet from the official Eclipse documentation. Add this network to your Hardhat or MetaMask configuration to enable contract deployment and interaction.

Write and Compile Your Solidity Smart Contract

Create a simple Solidity contract (e.g., a basic storage contract) in your project directory. Use Hardhat to compile the contract, ensuring there are no errors and the output is ready for deployment.

Deploy the Contract to Eclipse

Use Hardhat's deployment scripts or CLI to deploy your compiled contract to the Eclipse EVM rollup testnet. Confirm the transaction and note the deployed contract address for later testing.

Test Your Deployed Contract

Interact with your deployed contract using Hardhat scripts or a tool like Remix or Etherscan (if supported by Eclipse). Execute functions (e.g., set and get values) to verify that your contract behaves as expected on the testnet.

Monitor and Debug Transactions

Use block explorers or Hardhat's built-in tools to monitor transactions and logs on the Eclipse EVM rollup. Debug any failed transactions by reviewing error messages and contract events.

Smart contract integration is seamless on Eclipse’s EVM layer. You can deploy existing Ethereum contracts with minimal code changes, thanks to robust compatibility. Tools like Hardhat and Truffle remain fully supported, and developer experience mirrors what you’d expect from Ethereum Layer 2s. For those interested in cross-chain composability, Eclipse’s shared settlement layer unlocks new patterns for dApp interoperability, enabling messaging and asset transfers between isolated rollups without sacrificing security.

Testing Your Rollup: Best Practices

Before going live, comprehensive testing on testnet is critical. This includes:

• Contract-level unit tests using frameworks like Hardhat or Foundry
• Performance benchmarking to evaluate transaction throughput under different data availability backends
• Security audits, both automated and manual, to ensure your rollup’s configuration doesn’t introduce vulnerabilities
• User acceptance testing (UAT) with real wallets and simulated mainnet conditions
