# What is an account?

An account is digital identity represented by a unique address, which holds and transacts cryptocurrencies and other digital assets, and interacts with other accounts on the blockchain.

On the Ethereum network, accounts are classified into two types:

* Externally Owned Accounts (EOAs)
* Smart Contract Accounts (SCAs)

Transactions on Ethereum originate exclusively from EOAs, which are typically established and accessed via web3 wallets that support EOAs.
