smart-accounts-kit

Web3 development using MetaMask Smart Accounts Kit. Use when the user wants to build dApps with ERC-4337 smart accounts, send user operations, batch transactions, configure signers (EOA, passkey, multisig), implement gas abstraction with paymasters, create delegations, or request advanced permissions (ERC-7715). Supports Viem integration, multiple signer types (Dynamic, Web3Auth, Wagmi), gasless transactions, and the Delegation Framework.

Quick Reference

This skill file provides quick access to the MetaMask Smart Accounts Kit v0.3.0. For detailed information, refer to the specific reference files.

📚 Detailed References:

Smart Accounts Reference - Account creation, implementations, signers
Delegations Reference - Delegation lifecycle, scopes, caveats
Advanced Permissions Reference - ERC-7715 permissions via MetaMask

Package Installation

npm install @metamask/smart-accounts-kit@0.3.0

For custom caveat enforcers:

forge install metamask/delegation-framework@v1.3.0

Core Concepts Summary

1. Smart Accounts (ERC-4337)

Three implementation types:

Hybrid (Implementation.Hybrid) - EOA + passkey signers
Multisig (Implementation.MultiSig) - Multiple signers with threshold
Stateless7702 (Implementation.Stateless7702) - EIP-7702 upgraded EOA

2. Delegation Framework (ERC-7710)

Grant permissions from delegator to delegate:

Scopes - Initial authority (spending limits, function calls)
Caveats - Restrictions enforced by smart contracts
Types - Root, open root, redelegation, open redelegation
Lifecycle - Create → Sign → Store → Redeem

3. Advanced Permissions (ERC-7715)

Request permissions via MetaMask extension:

Human-readable UI confirmations
ERC-20 and native token permissions
Requires MetaMask Flask 13.5.0+
User must have smart account

Quick Code Examples

Create Smart Account

import { Implementation, toMetaMaskSmartAccount } from '@metamask/smart-accounts-kit'
import { privateKeyToAccount } from 'viem/accounts'

const account = privateKeyToAccount('0x...')

const smartAccount = await toMetaMaskSmartAccount({
  client: publicClient,
  implementation: Implementation.Hybrid,
  deployParams: [account.address, [], [], []],
  deploySalt: '0x',
  signer: { account },
})
