Configuration

Configuration of hardhat's network or other hardhat specific config is done via hardhat.config.ts

Else rocketh.ts/js is where you can configure hardhat-deploy/rocketh specific configs.

1. namedAccounts (ability to name addresses)

The rocketh.js file need to export a config object

For example

import {UserConfig} from 'rocketh';
export const config = {
	accounts: {
		deployer: {
			default: 0,
      sepolia: 1
		},
		admin: {
			default: 1,
		},
	},
} as const satisfies UserConfig;

import * as artifacts from './generated/artifacts.js';
export {artifacts};

This config file import modules too so that deploy script can simply import rocketh.js to have access to artifacts and specific functions

The named account feature allow you to define accounts by name and have them configurable by environment

In the above file, the deployer is set to be the first account on all environment, except for sepolia where it is the second

4. deterministicDeployment (ability to specify a deployment factory)

---

The config also allow you to set an optional deterministicDeployment field.

deterministicDeployment allows you to associate information that are used on each chain for deterministic deployment. The information for each deterministic deployment consist out of a factory, a deployer, the required funding and a signedTx to deploy the factory. The default deterministic deployment used is the Deterministic Deployment Proxy. The factory expects a 32 bytes salt concatenated with the deployment data (see EIP-1014 for more information on these parameters).

Using the deterministicDeployment it is possible to define a different setup for the deterministic deployment. One use case for this is the deterministic deployment on networks that required replay protection (such as Celo or Avalanche). The Deterministic Deployment Proxy can only be deployed on networks that don't enforce replay protection, therefore on other networks an alternative library has to be used. An example for this would be the Safe Singleton Factory that is an adjusted version of the Deterministic Deployment Proxy that contains signed transactions that include replay protection.

import {UserConfig} from 'rocketh';
export const config = {
	accounts: {
		deployer: {
			default: 0,
      sepolia: 1
		},
		admin: {
			default: 1,
		},
	},
  chains: {
    sepolia: {
        factory: '0x4e59b44847b379578588920ca78fbf26c0b4956c',
        deployer: '0x3fab184622dc19b6109349b94811493bf2a45362',
        funding: '10000000000000000',
        signedTx:
          '0xf8a58085174876e800830186a08080b853604580600e600039806000f350fe7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffe03601600081602082378035828234f58015156039578182fd5b8082525050506014600cf31ba02222222222222222222222222222222222222222222222222222222222222222a02222222222222222222222222222222222222222222222222222222222222222',
      }
  }
} as const satisfies UserConfig;
