# Instantiation

<Info>
  Before doing anything with the SDK, we must instantiate it.
  This will create the Etherspot smart account based off of the values we pass in.
</Info>

Step 1. Import the Etherspot Prime SDK.

```javascript theme={null}
  import { PrimeSdk } from '@etherspot/prime-sdk';
```

Step 2. Instantiate the SDK with a private key and Chain ID using this block of code.

```javascript theme={null}
  const primeSdk = new PrimeSdk(
    { privateKey: process.env.WALLET_PRIVATE_KEY }, 
    { 
      chainId: Number(process.env.CHAIN_ID), 
    },
  );
```

And that's it! You're now ready to call any of the Prime SDK [functions.](/prime-sdk/functions)

You can also pass in different parameters when instantiating the SDK.

* chainId : The chain ID of the blockchain.
* entryPointAddress : The 4337 entry point address you wish to use.
* bundlerRpcUrl : The bundler you wish to use.
* walletFactoryAddress : The wallet factory implementation you wish to use.

An example of how to configure this is shown below:

```javascript theme={null}
  const primeSdk = new PrimeSdk(
    { privateKey: process.env.WALLET_PRIVATE_KEY },
    {
      chainId: 123,
      entryPointAddress: '0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789',
      rpcProviderUrl: 'https://fusetestnet-bundler.etherspot.io/',
      walletFactoryAddress: '0x7f6d8F107fE8551160BD5351d5F1514A6aD5d40E',
    },
  );
```

You can check **primeSdk.state()** to check if the Etherspot network is up and running correctly.
