# Account

## Overview

The **Account** module represents an Ethereum account that can sign messages, transactions, typed data, and authorizations.

Viem distinguishes between two kinds of account:

* **Local Account**: signing happens locally through a private key, mnemonic, KMS, or other signing logic. The raw signing material is available to your program.
* **JSON-RPC Account**: signing is delegated to a JSON-RPC provider (for example, a browser wallet). Only the address is known.

```ts twoslash
import { Account } from 'viem'

const account = Account.fromPrivateKey('0x...')

account.address
// '0x...'
```
