# Account

Interface representing a single account within a Stacks wallet. Contains the private keys and metadata needed for STX transactions, Gaia storage, and app-specific key derivation.

***

### Usage

```ts
import { generateWallet, getStxAddress, Account } from '@stacks/wallet-sdk';

const wallet = await generateWallet({
  secretKey: 'your 24-word seed phrase ...',
  password: 'password',
});

const account: Account = wallet.accounts[0];

console.log(account.index);          // 0
console.log(account.stxPrivateKey);  // hex string — used for STX transactions
console.log(account.dataPrivateKey); // hex string — used for Gaia/profiles
console.log(account.appsKey);       // xprv... — root for app-specific keys
console.log(account.salt);           // hex string — wallet-level salt
```
