# Smart Contract Wallets

> Explaining accounts on Ethereum

If you're new to Account Abstraction it's important to know the differences between accounts.

Ethereum has two account types:

**Externally-owned account (EOA)**: Controlled by anyone with the private keys, the type of account Metamask/TrustWallet/Web3Auth uses.

**Smart Contract Wallet(SCW)**: a smart contract deployed to the network, controlled by code. The type of account an Etherspot wallet is.

</p>

Both account types have the ability to:

* Receive, hold and send ETH and tokens
* Interact with deployed smart contracts

With Etherspot, we take an EOA as a parameter when [instantiating the SDK](/prime-sdk/instantiation).
This EOA will be the owner of the new Etherspot Smart Contract Wallet that is created.

<Info>
  There will be two addresses, the original EOA address and the
  new Etherspot SCW address created by the SDK.

  **We only want to fund and use the Etherspot SCW address
  as this let's us make use of Etherspot's great Account Abstraction features.**
