# onWalletConnectionFailed

<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)](/javascript/reference/react-quickstart) to get started.
</Card>

### Summary

This callback will be called when a wallet connection fails.

### Usage

If you're calling it in the DynamicContextProvider:

```TypeScript theme={"system"}
<DynamicContextProvider
  settings={{
    events: {
      onWalletConnectionFailed: (walletConnector, error) => {
        console.log('walletConnectionFailed', walletConnector, error);
      }
    }
  }}
>
```

If you need to call it anywhere else in the code:

```TypeScript theme={"system"}
dynamicEvents.on('walletConnectionFailed', (walletConnector, error) => {
  console.log('walletConnectionFailed', walletConnector, error);
});
```

### Callback Argument Value

```TypeScript theme={"system"}
walletConnectionFailed: (
  walletConnector: WalletConnector,
  error: unknown,
) => void;
```

This is called with the wallet connector that failed to connect and the error that occurred.
