• 🔄 Deterministic Deployments - Support for CREATE2 and CREATE3 deployment patterns
• 💎 Diamond Pattern - First-class support for EIP-2535 Diamond proxies
• 🔀 Proxy Patterns - Support for ERC1967, UUPS, Transparent, and ERC173 proxies
• 📦 Named Accounts - Reference accounts by name instead of address
• 💾 Deployment Tracking - Save and track deployments with transaction receipts
• ✅ Contract Verification - Built-in support for Etherscan and Sourcify
• 📄 Documentation Generation - Auto-generate documentation from deployed contracts

Getting Started

In this guide, we will create a new project using Rocketh from scratch..

Note if you want to use a full featured template, you can use the template-ethereum-contracts repository.

You can also use hardhat-deploy init, see hardhat-deploy for more information.

We will be using hardhat for contract compilation and hardhat-deploy to hook hardhat with rocketh.

Note While rocketh is agnostic to the compilation system you use, it require one and for this guide we will use hardhat.

Prerequisites

• Node.js (v20 or later)
• pnpm (v9 or later)

create a new directory and cd into it

We will be working in that folder going forward.

mkdir my-rocketh-project
# set the current directory
cd my-rocketh-project

initialize a new project

Just create a new package.json file with the following content:

file: package.json

{
	"name": "my-rocketh-project",
	"version": "0.0.0",
	"type": "module"
}

install dependencies

pnpm add -D hardhat @types/node typescript forge-std@github:foundry-rs/forge-std#v1.9.4 hardhat-deploy rocketh @rocketh/node @rocketh/deploy @rocketh/read-execute

create a new solidity file

First we create a new directory for our solidity files.

mkdir src

Then we create a new solidity file in that folder.

file: src/Counter.sol

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.28;

contract Counter {
  uint public x;

  event Increment(uint by);

  function inc() public {
    x++;
    emit Increment(1);
  }

  function incBy(uint by) public {
    require(by > 0, "incBy: increment should be positive");
    x += by;
    emit Increment(by);
  }
}

create a new hardhat config file

We then create a new hardhat config file.

file: hardhat.config.ts

import {defineConfig} from 'hardhat/config';
import HardhatDeploy from 'hardhat-deploy';

export default defineConfig({
	plugins: [HardhatDeploy],
	solidity: {
		profiles: {
			default: {
				version: '0.8.28',
			},
			production: {
				version: '0.8.28',
				settings: {
					optimizer: {
						enabled: true,
						runs: 200,
					},
				},
			},
		},
	},
	networks: {
		hardhatMainnet: {
			type: 'edr-simulated',
			chainType: 'l1',
		},
		hardhatOp: {
			type: 'edr-simulated',
			chainType: 'op',
		},
	},
	paths: {
		sources: ['src'],
	},
	generateTypedArtifacts: {
		destinations: [
			{
				folder: './generated',
				mode: 'typescript',
			},
		],
	},
});

create a new rocketh directory

Then we setup a rocketh by first creating a new directory for rocketh configurations.

mkdir rocketh

create a new rocketh config file

We create the rocketh config file.

file: rocketh/config.ts

/// ----------------------------------------------------------------------------
// Typed Config
// ----------------------------------------------------------------------------
import type {UserConfig} from 'rocketh/types';

// we define our config and export it as "config"
export const config = {
	accounts: {
		deployer: {
			default: 0,
		},
		admin: {
			default: 1,
		},
	},
	data: {},
} as const satisfies UserConfig;

// then we import each extensions we are interested in using in our deploy script or elsewhere

// this one provide a deploy function
import * as deployExtension from '@rocketh/deploy';
// this one provide read,execute functions
import * as readExecuteExtension from '@rocketh/read-execute';

// and export them as a unified object
const extensions = {
	...deployExtension,
	...readExecuteExtension,
};
export {extensions};

// then we also export the types that our config ehibit so other can use it

type Extensions = typeof extensions;
type Accounts = typeof config.accounts;
type Data = typeof config.data;

export type {Extensions, Accounts, Data};

create a new rocketh deploy file

the rocketh deploy file is used to export the deploy script function and the artifacts.

file: rocketh/deploy.ts

import {type Accounts, type Data, type Extensions, extensions} from './config.js';

// ----------------------------------------------------------------------------
// we re-export the artifacts, so they are easily available from the alias
import * as artifacts from '../generated/artifacts/index.js';
export {artifacts};
// ----------------------------------------------------------------------------
// we create the rocketh functions we need by passing the extensions to the
//  setup function
import {setupDeployScripts} from 'rocketh';
const {deployScript} = setupDeployScripts<Extensions, Accounts, Data>(extensions);

export {deployScript};

create a new rocketh environment file

the environment file is used to export the environment functions, to be used in test and scripts.

file: rocketh/environment.ts

import {type Accounts, type Data, type Extensions, extensions} from './config.js';
import {setupEnvironmentFromFiles} from '@rocketh/node';
import {setupHardhatDeploy} from 'hardhat-deploy/helpers';

// useful for test and scripts, uses file-system
const {loadAndExecuteDeploymentsFromFiles} = setupEnvironmentFromFiles<Extensions, Accounts, Data>(extensions);
const {loadEnvironmentFromHardhat} = setupHardhatDeploy<Extensions, Accounts, Data>(extensions);

export {loadEnvironmentFromHardhat, loadAndExecuteDeploymentsFromFiles};

create a new deploy directory

Then we can create a new deploy directory where our deploy scripts will be stored.

mkdir deploy

create a new deploy script

And here we create a basic deploy script for our Counter contract.

file: deploy/deploy_Counter.ts

import {deployScript, artifacts} from '../rocketh/deploy.js';

export default deployScript(
	async ({deploy, namedAccounts}) => {
		const {deployer} = namedAccounts;

		await deploy('Counter', {
			account: deployer,
			artifact: artifacts.Counter,
		});
	},
	{tags: ['Counter', 'Counter_deploy']},
);

compile

We can now compile our contracts using the following command:

pnpm hardhat compile

deploy

And finally we can deploy our contracts in a in-memory hardhat network using the following command:

pnpm hardhat deploy
