# Lit <> Alchemy Account Abstraction

Snowball offers simple APIs to integrate Alchemy's account abstraction features intor your application. It hooks into Snowball's existing auth API, allowing you to set everything up in one seamless package.

This guide will walk you through setting up account abstraction with Alchemy + Lit auth in your application.

# Getting Started

To get started with account abstraction, first install the dependencies:

bash

npm install @snowballtools/js-sdk @snowballtools/auth-lit @snowballtools/link-lit-alchemy-light

Then initialize Snowball with both auth and smart wallet features:

javascript

import { LitPasskeyAuth } from '@snowballtools/auth-lit'
import { Snowball, SnowballChain } from '@snowballtools/js-sdk'
import { LinkLitAlchemyLight } from '@snowballtools/link-lit-alchemy-light'

import { alchemyApiKey_sepolia, alchemyGasPolicyId_sepolia, litRelayApiKey } from './constants'

export const snowball = Snowball.withAuth({
  passkey: LitPasskeyAuth.configure({ litRelayApiKey }),
})
  .withSmartWallet(
    LinkLitAlchemyLight.pkpEthersWallet.configure({
      alchemyApiKeys: {
        [SnowballChain.sepolia.chainId]: {
          apiKey: alchemyApiKey_sepolia,
          gasPolicyId: alchemyGasPolicyId_sepolia,
        },
      },
    }),
  )
  .create({
    initialChain: SnowballChain.sepolia,
  })

Although this example uses LitPasskeyAuth, you can swap it with any Lit auth that Snowball provides.
