# Changing Wallet Factory

With the Etherspot Prime SDK we have the option to use some different
smart contract wallet implementations with the Etherspot infrastructure.

When instantiating the SDK, there is an optional parameter called **factoryWallet**.
If this is not included then it will default to Factory.ETHERSPOT and use our wallet factory.

Currently we have added support for ZeroDev and simpleAccount.

## ZeroDev instantiation

Factory contract address: 0x5de4839a76cf55d0c90e2061ef4386d962E15ae3

```javascript theme={null}
import { Factory, PrimeSdk } from '../src';
import * as dotenv from 'dotenv';
dotenv.config();

async function main() {
  const primeSdk = new PrimeSdk({ privateKey: process.env.WALLET_PRIVATE_KEY }, { chainId: Number(process.env.CHAIN_ID), 
  factoryWallet: Factory.ZERO_DEV, bundlerProvider: new EtherspotBundler(Number(process.env.CHAIN_ID), bundlerApiKey) })
}
```

## simpleAccount instantiation

Factory contract address: 0x9406Cc6185a346906296840746125a0E44976454

```javascript theme={null}
import { Factory, PrimeSdk } from '../src';
import * as dotenv from 'dotenv';
dotenv.config();

async function main() {
  const primeSdk = new PrimeSdk({ privateKey: process.env.WALLET_PRIVATE_KEY }, { chainId: Number(process.env.CHAIN_ID), 
  factoryWallet: Factory.SIMPLE_ACCOUNT, bundlerProvider: new EtherspotBundler(Number(process.env.CHAIN_ID), bundlerApiKey) })
}
```
