Install Catapulta CLI

$ Terminal

npm i -g catapulta

Deploy smart contracts anywhere in 5 minutes, without faucets

Catapulta allows you to deploy to any network with a simple command, and with the --sponsor flag it will provide with all the gas needed for your deployment in testnet networks:

$ Run in your Foundry project

catapulta script scripts/Deploy.s.sol --network sepolia --sponsor

Multi-chain ready

Provide more networks in the --network params to deploy multi-chain with Foundry.

$ Run in your Foundry project

catapulta script scripts/Deploy.s.sol --network amoy,sepolia,fuji --sponsor

Queue your deployment with GasHawk and save gas

Save lots of gas using GasHawk service to queue a full deployment which will be broadcasted when gas prices are low.

$ Run in your Foundry project

catapulta script scripts/Deploy.s.sol --network sepolia --gas-hawk

Verify anywhere, automatically

Forget about faucets

Use the --sponsor flag and Catapulta will fund your deployer account with the amount needed for any testnet deployment.

Keep track of all your deployments, in a single place

Share reports with your team

By default all reports are private, but you can make them public to share with your users, clients or team members.

Deploy in +20 networks without native gas

Gas abstraction for developers

Fund your project with USD or stablecoins, and deploy anywhere in 20 EVM networks. We take care of funding your deployer addresses without code changes. We support all accounts supported by Foundry or Hardhat, like private keys, mnemonics, Ledger, or Amazon KMS.

Forget about RPC endpoints

Specify the network name and Catapulta will route the transactions, without RPC endpoints or block explorer configs. We take care of infra so you can focus on code.

Your private keys, better with you

All transaction signing occurs locally in your machine using Hardhat or Foundry, as always. Once signed, the Catapulta RPC Relay will determine gas costs and fund your deployer account.

Deploy in +20 networks, with zero configs

Perform complex multi-chain deployments with a single CLI command.

What Solidity developers say about Catapulta?

"Honestly it's worth it. Verification on all chains without problems and without having to generate x api keys. For chains with multiple explorer it even verified on all of them."

@sakulstra

Senior Solidity at BGD Labs

"Verification was a major issue for us, considering the complexity of the contracts and the dozen libraries used. Catapulta automated that process, and integration only required editing a single line in our deployment script."

vicnaum.lens

Senior Solidity at Lens

"Catapulta saves a significant amount of time during deployment by eliminating the need to configure RPCs Providers and Etherscan APIs for contract verification, and provides a comprehensive Deployment Report."

Deploy anywhere with Catapulta

With Catapulta you can deploy & get verified in multiple block explorers at +20 networks and aims to supports all popular networks with only a single subscription. All of this, without the need of native gas in each chain.

Pay once, deploy anywhere in Web3.

Delegated Etherscan verification

Once you deploy, Catapulta starts a separate instance which performs the verification of smart contracts in block explorers. In the meantime, you can focus on coding or enjoy your time, instead of dealing with verification errors, API keys, captchas and manual work.

Automated deployment dashboards

Deployment reports are critical yet there is no standard about what do you need to save after a deployment. You must save your compilation artifacts in each deployment, due you may need it in the future for replicating a deployment in the case you want to expand to another network via CREATE2 or during a deployment audit.

Once your deployment session is finished, Catapulta generates a deployment report and collects all contract names, contract addresses, commit hash, txs, artifacts and ABIs and stores the report in your private dashboard.

Each deployment report is individual from the rest of deployments, enabling you to debug better a deployment session and keep context.

Private testnets and forks with BuildBear

With Catapulta CLI you can deploy directly to a private testnet via BuildBear Sandbox. The sandbox allows you to deploy and interact with other protocols in mainnet networks, but in a private network without worrying about gas. Catapulta report

Collaborative deployments dashboard

Invite your team members or clients to a Catapulta project, and they will have access to your deployments, contract addresses, and ABIs. Perfect for sharing deployments between departments or clients.

No code changes or configs needed

Forget about setting up RPC urls and API keys in your project configuration file, with the Catapulta CLI you can deploy with just specifying the network name or chain id. Currently we support +20 networks where you can deploy directly from Foundry or Hardhat.

Track your transaction costs

Catapulta allows to track your deployment costs across different projects and networks, helping to keep track your gas usage.

Contracts ABI Hosting

All the artifacts can always be retrieved via Catapulta Storage, you can download a JSON report from the report page or copy the JSON report URL and be able to load your contracts directly in your frontend or backend. With this feature you can skip building your own S3 backend for storing your contract artifacts.

What's next with Catapulta?

Catapulta aims to make your Web3 development easier, bringing a faster & safer environment for developers. In the future you will be able to link your Github repositories and directly perform deployments from your browser or CI/CD, without a terminal or console. And many more features that are in the pipeline.

We take feature requests from developers very seriously, if you want to request a new feature, contact us!
