Catapult: simple smart contracts deployments

September 10 2025

As a web3 developer, you're constantly pushing the boundaries of what's possible whenever building decentralized applications, whether DeFi platforms, multichain stablecoin deployments, cross-chain payment experiences, or groundbreaking web3 gaming experiences.

But with this innovation comes complexity, especially when it comes to deploying and managing smart contracts across multiple EVM chains.

That's why we're thrilled to announce the launch of Catapult, a revolutionary tool that simplifies and automates your smart contract deployment process.

What is Catapult?

In a nutshell, Catapult is your new best friend for deploying smart contracts. It’s a powerful, declarative, and composable deployment runner that takes the headache out of bringing your onchain creations to life.

Think of it as a supercharged CI/CD pipeline specifically designed for web3 development. Instead of writing and maintaining complex, imperative scripts, Catapult allows you to define the desired state of your smart contracts in a simple, human-readable format.

Catapult then takes over, figuring out the most efficient and reliable way to get you there, whether you're deploying to a single testnet or a dozen mainnet environments.

Why Catapult?

So, why should Catapult be a part of your web3 stack? Here are just a few of the benefits that make it an essential tool:

• Effortless multi-chain deployments: In a world of chain abstraction and cross-chain interoperability, deploying to a single network is no longer enough. Catapult is built from the ground up for a multi-chain reality. With a single command, you can deploy your smart contracts across any EVM chain, ensuring consistency and saving you countless hours of manual work. This makes it the perfect tool for building a robust, multi-chain ecosystem for your web3 app.
• Say goodbye to deployment errors: Manual deployments are fraught with risk. A single mistake can lead to costly errors and security vulnerabilities. Catapult’s declarative approach eliminates this risk by ensuring your deployments are repeatable, hermetic, and deterministic. You can even perform a "dry run" to validate your deployment plan before a single transaction is sent, giving you complete peace of mind.
• Seamless integration with your existing workflow: Catapult is designed to fit right into your existing web3 development platform and workflow. It's compatible with popular tools like Hardhat and Foundry, so you don't have to change the way you work to reap the benefits. Plus, it can be easily integrated into your existing CI/CD pipelines, enabling fully automated, gasless transactions for your deployments.
• Focus on building great products: Your time is best spent building amazing web3 experiences, not wrestling with deployment scripts. Catapult automates the tedious and error-prone parts of the deployment process, freeing you up to focus on what you do best: innovating and creating value for your users.

Use cases: How Catapult may empower your web3 development

The possibilities with Catapult are endless, but here are a few examples of how it can revolutionize your workflow:

• Web3 gaming: Launch your next hit web3 game with confidence. Deploy your NFT contracts, in-game marketplaces, and other smart contracts across multiple chains to reach the widest possible audience.
• DeFi: Ensure the security and reliability of your DeFi protocols with auditable and repeatable deployments. Catapult's deterministic nature gives you and your users the confidence that your contracts are deployed exactly as intended.
• Stablecoins: Catapult ensures your audited stablecoin contracts are deployed identically across every EVM chain. This deterministic, repeatable process is essential for building trust and reliability in your web3 payment and DeFi ecosystem.
• Web3 wallets and payments: If you're building a web3 wallet or a crypto checkout solution, Catapult can help you manage the deployment of your smart contracts across multiple chains, ensuring a seamless user experience.
