# Check Balances

This guide explains how to check [native TRX balances](#native-trx-balance), [TRC20 token balances](#trc20-token-balance), and [read-only account balances](#read-only-account-balances).

## Native TRX Balance

You can retrieve the native TRX balance using [`account.getBalance()`](https://docs.wdk.tether.io/sdk/wallet-modules/api-reference#getbalance):

{% code title="Get Native TRX Balance" lineNumbers="true" %}

```javascript
const balance = await account.getBalance()
console.log('Native TRX balance:', balance, 'sun')
```

{% endcode %}

{% hint style="info" %}
On Tron, values are expressed in sun (1 TRX = 1,000,000 sun).
{% endhint %}

## TRC20 Token Balance

You can check the balance of a specific TRC20 token using [`account.getTokenBalance()`](https://docs.wdk.tether.io/sdk/wallet-modules/api-reference#gettokenbalance-tokenaddress):

{% code title="Get TRC20 Token Balance" lineNumbers="true" %}

```javascript
const trc20Address = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t' // USDT
const trc20Balance = await account.getTokenBalance(trc20Address)
console.log('TRC20 token balance:', trc20Balance)
```

{% endcode %}

## Read-Only Account Balances

You can check balances for any Tron address without a seed phrase using [`WalletAccountReadOnlyTronGasfree`](https://docs.wdk.tether.io/sdk/wallet-modules/api-reference#walletaccountreadonlytrongasfree):

{% code title="Create Read-Only Account" lineNumbers="true" %}

```javascript
import { WalletAccountReadOnlyTronGasfree } from '@tetherto/wdk-wallet-tron-gasfree'

const readOnlyAccount = new WalletAccountReadOnlyTronGasfree('TLyqzVGLV1srkB7dToTAEqgDSfPtXRJZYH', {
  chainId: 728126428,
  provider: 'https://api.trongrid.io',
  gasFreeProvider: 'https://gasfree.provider.url',
  gasFreeApiKey: 'your-api-key',
  gasFreeApiSecret: 'your-api-secret',
  serviceProvider: 'TLyqzVGLV1srkB7dToTAEqgDSfPtXRJZYH',
  verifyingContract: 'TLyqzVGLV1srkB7dToTAEqgDSfPtXRJZYH'
})
```

{% endcode %}

You can retrieve the native balance from a read-only account using [`readOnlyAccount.getBalance()`](https://docs.wdk.tether.io/sdk/wallet-modules/api-reference#getbalance):

{% code title="Read-Only Native Balance" lineNumbers="true" %}

```javascript
const balance = await readOnlyAccount.getBalance()
console.log('Read-only account balance:', balance)
```

{% endcode %}

{% hint style="info" %}
You can also create a read-only account from an existing owned account using [`account.toReadOnlyAccount()`](https://docs.wdk.tether.io/sdk/wallet-modules/api-reference#toreadonlyaccount).
{% endhint %}
