# useSendEvmTransaction

```ts theme={null}
function useSendEvmTransaction(): {
  sendEvmTransaction: (options: SendEvmTransactionOptions) => Promise<SendEvmTransactionResult>;
  data: TransactionState;
};
```

Hook that provides a wrapped function to send EVM transactions with authentication checks.
This hook uses useEnforceAuthenticated to ensure the user is signed in before attempting to send.
The hook internally waits for transactions to succeed and returns the related success/error
via the `data` discriminated union object.

Note: The `data` returned from the hook only represents the *last* sent transaction. If you wish to
call one instance of the hook multiple times in quick succession it is recommended to save the
txHash returned from `sendEvmTransaction` yourself and handle waiting for the receipt.

## Returns

```ts theme={null}
{
  sendEvmTransaction: (options: SendEvmTransactionOptions) => Promise<SendEvmTransactionResult>;
  data: TransactionState;
}
```
