Module SDK

A TypeScript library for using smart account modules in applications

The Module SDK allows you to:

• Easily install and uninstall modules for any ERC-7579 account
• Interact with and use modules using a simple and consistent API
• Can be used alongside existing account SDKs such as permissionless.js, Biconomy, Zerodev and many more
• Use core modules, such as:
  • Auto Savings: Automatically allocate a set percentage of any incoming token to a target vault
  • ColdStorage Hook: Restrict all transactions with a timelock and only allow funds to be sent to a single address
  • Deadman Switch: Recover an account after a specified inactive period
  • Hook Multiplexer: Combine multiple hooks into one with fine-grained control over when they are called
  • Multi Factor: Use multiple validators in combination as a multi-factor authentication system
  • Ownable Executor: Allow an account to control a subaccount and pay for its transaction fees
  • Ownable Validator: Authenticate on your account with multiple ECDSA keys
  • Registry Hook: Query the Module Registry before installing and using modules
  • Scheduled Orders: Execute swaps on a specified schedule
  • Scheduled Transfers: Transfer funds on a specified schedule
  • Social Recovery: Recover your account using a set of guardians

In-depth documentation is available at docs.rhinestone.wtf.

Using the ModuleSDK

Installation

Install viem as a peer dependency and then install the Module SDK:

npm install viem @rhinestone/module-sdk

pnpm install viem @rhinestone/module-sdk

yarn add viem @rhinestone/module-sdk

bun install viem @rhinestone/module-sdk

Quick Start

// Import the required functions
import {
  installModule,
  getModule,
  getAccount,
  getClient,
  getMultiFactorValidator,
} from '@rhinestone/module-sdk'

// Create a client for the current network
const client = getClient({
  rpcUrl: 'https://rpc.ankr.com/eth	',
})

// Create the module object if you are using a custom module
const moduleToInstall = getModule({
  module: moduleAddress,
  data: initData,
  type: moduleType,
})

// Or use one of the existing modules
moduleToInstall = getMultiFactorValidator({
  threshold: 2,
  validators: [
    {
      packedValidatorAndId: '0x123...',
      data: '0x123...',
    },
    {
      packedValidatorAndId: '0x456...',
      data: '0x123...',
    },
  ],
})

// Create the account object
const account = getAccount({
  address: '0x123...',
  type: 'erc7579-implementation',
})

// Get the executions required to install the module
const executions = await installModule({
  client,
  account,
  moduleToInstall,
})

// Install the module on your account, using your existing account SDK
// note: this is an example, you should use your own account SDK
accountSDK.execute(executions)
