# Token Balances

<Card title="Recommended: JavaScript SDK with React Hooks" icon="react" color="#4779FE">
  For new React apps, we recommend the JavaScript SDK with React Hooks (`@dynamic-labs-sdk/react-hooks`) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the [React quickstart (JavaScript SDK)](/docs/javascript/reference/react-quickstart) to get started.
</Card>

### Hooks

[useTokenBalances](/docs/react/reference/hooks/usetokenbalances) - A React hook that fetches token balances for an account on a specified network. Returns token balances with optional fiat prices and native balance inclusion.

[useMultichainTokenBalances](/docs/react/reference/hooks/usemultichaintokenbalances) - A React hook that fetches token balances across multiple chains and networks for linked wallet addresses.

### Caching information

Token balances are cached for `15 seconds` by default unless force refreshing

### Rate Limiting when using the `forceRefresh` feature of `useTokenBalances`

To prevent abuse of force refreshing the balances, we have implemented configurable rate limiting on this feature.
The default limits are as follows

* You cannot request a refresh within `1 minute` of the previous refresh
* You can only refresh 3 times within a `5 minute` period
* You can only force refresh 40 times a day

<Note>
  If you would like higher limits, please reach out to our sales team.
