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
datadiscriminated union object.Note: The
datareturned 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 fromsendEvmTransactionyourself and handle waiting for the receipt.
